Combination of hydrodynamic cavitation with CoFe2O4 photocatalyst for activation of peracetic acid under UVC irradiation in synergistic degradation of bisphenol A

This study was aimed at activating peracetic acid (PAA) to degrade bisphenol A (BPA) in aqueous media by combining a system of hydrodynamic cavitation (HC) with CoFe2O4 photocatalyst under UVC irradiation. The CoFe2O4 was successfully synthesized and characterized by various characterization techniques. The influence of various HC approaches alone and combined with photocatalysis on the BPA degradation was explored. After 60 min reaction, the BPA degradation efficiency achieved by CoFe2O4, UV, HC, and PAA individually was 0.69 %, 2.77 %, 6.45 %, and 14.23 %, respectively. At same experimental conditions, under the CoFe2O4 + HC + UV, CoFe2O4 + HC + PAA, CoFe2O4 + UV + PAA and CoFe2O4 + HC + UV + PAA processes, BPA degradation rates were 68.47 %, 77.91 %, 84.23 % and 97.29 %, respectively. The BPA degradation efficiency was examined under various operational parameters, including pH (3−11), BPA concentration (20–40 mg/L), load of CoFe2O4 (0.1–0.4 g/L), PAA dosage (50–200 μmol/L), inlet pressure (1.0–4.0 bar), and reaction time (0–60 min). 97.29 % BPA was degraded over 60 min in the ideal reaction conditions (pH: 7.0, BPA: 20 mg/L, CoFe2O4: 0.4 g/L, PAA: 200 μmol/L, inlet pressure:4.0 bar). BothO·Hradicals and R−O.were contributed to BPA reaction system, andO·Hplayed as the dominant contributor. Overall, CoFe2O4 + HC + UV + PAA system provides a low-energy and low-cost strategy for degrading and mineralizing organic contaminants from waters.

Perovskite oxide nanoparticles: Dual role as supports for luminescent Eu(III) ions and photocatalysts for bisphenol degradation

Perovskite oxides, such as CaTiO3, SrTiO3, and BaTiO3, have gained significant recognition for their dual role as luminescence supports and photocatalytic materials. In this study, we synthesized perovskite oxide nanoparticles (NPs) using the thermal calcination method and employed them as photocatalysts for the degradation of bisphenol S (BPS) and bisphenol AF (BPAF) under UVC irradiation. The as-synthesized photocatalysts were thoroughly examined for the photocatalytic degradation process and identified secondary products were identified using liquid chromatography in conjunction with high-resolution mass spectrometry. Our observations highlighted the relatively faster photocatalytic degradation of BPS compared to BPAF. Notably, among the perovskite oxide materials, SrTiO3 exhibited the highest catalytic activity for BPS degradation, while BaTiO3 outperformed in the case of BPAF degradation. Perovskite oxide NPs were also utilized as supports for doping with Eu3+ ions to create phosphor supports. Luminescent emissions from the Eu3+ ions, characterized by the 5D0 → 7FJ = 0-4 transitions, were observed and varied depending on the support material. Notably, Eu3+ doped in CaTiO3 nanoparticles exhibited the highest luminescence efficiency. These results highlight the dual functionality of perovskite oxide-based materials in phosphor applications and photocatalysis, offering valuable insights into their potential for both enhancing luminescence efficiency and treating bisphenols.

Efficient and low-energy consumption degradation of bisphenol A in aqueous solutions and its density functional theory calculation

An advanced Fenton technique using urea peroxide (UHP) as an oxidant was studied for the degradation of bisphenol A (BPA) in aqueous solution. Compared to the H2O2/Fe(II) system, the UHP/Fe(II) system performs noticeably better in terms of degradation and requires less catalyst. The mechanism by which UHP exhibits unique and remarkable properties has been elucidated at the molecular level (bond order, AIM analysis, ELF, Spin Population number, electron difference density maps) by density functional theory (DFT) calculations. The ELF and the electron density difference revealed that UHP created an intermediate coordination compound with six-coordinated iron (II), facilitating electron transfer and the disruption of O-O bonds because of the feeble O-O strength, leading to an increase in hydroxyl radicals. Consequently, UHP increases the rate of electron usage and targeting efficiency, which accelerates the breakdown of BPA. targeting efficiency, which accelerates the breakdown of BPA. Based on the intermediates determined by LC-MS/MS, the possible degradation pathway of BPA in the UHP/Fe(II) system were proposed, which was verified to be a lower energy consumption pathway by calculating the reaction energy barriers. It is expected to be an advanced Fenton technology with practical engineering applications potential, due to the advantages of wider pH window, lower energy consumption and higher electron utilization.

Degradation of Bisphenol A by manganese minerals: The impact of inorganic and organic ligands

Manganese minerals are ubiquitous in aquatic environments, where both inorganic and organic components can form complexes with them, thereby impacting the release of reactive Mn(III) and the fate of pollutants. The available information about these processes remains insufficient, however, impeding the study of the migration and transformation of pollutants in the environment. In this study, pyrophosphate and humic acid were selected as inorganic and organic ligands typical of aquatic environments, and their impacts on the degradation of Bisphenol A by the β- and δ- variants of MnO2 were investigated. The results indicate that 1.0–5.0 mM pyrophosphate promotes the generation of reactive Mn(III) from β-MnO2, resulting in enhanced degradation of Bisphenol A. Pyrophosphate inhibits δ-MnO2-mediated degradation of Bisphenol A due to competition for reactive sites. Humic acids increase the degradation of Bisphenol A mediated by δ-MnO2 by forming complexes with reactive Mn(III) released from the δ-MnO2. The degradation of Bisphenol A mediated by minerals in the presence of ligands occurs primarily through hydroxylation, one-electron transfer, and free radical coupling. These findings provide new insights into the role of ligands in the reductive dissolution of manganese minerals and their synergistic effect on the fate of Bisphenol A in aqueous environments.

Integrating detection and degradation of bisphenol A by photocatalytic fuel cell-driven photoelectrochemical sensor

To ensure food safety and environmental protection, it is crucial to rapidly identify and remove bisphenol A (BPA), a plasticizer commonly used in the inner lining of food containers and beverage packaging. Here, a photocatalytic fuel cell (PFC)-integrated self-powered photoelectrochemical (PEC) sensor is constructed. Unlike conventional single PEC or PFC sensors, this PFC-integrated PEC sensor relies on not only the difference in Fermi energy levels between photoanode and photocathode but also charge accumulation resulted from the oxidation of BPA by photogenerated holes. Consequently, this sensor achieved a remarkable maximum output power (Pmax) of 8.58 μW cm−2, as well as a high sensitivity, wide linear detection range (0.1–200 μM), low detection limit (0.05 μM), great stability, reproducibility, and real sample detection capability. This work integrates PFC and PEC technologies successfully for the rapid identification and efficient removal of BPA.

Degradation of Bisphenol A by Nitrogen-Rich ZIF-8-Derived Carbon Materials-Activated Peroxymonosulfate.

Bisphenol A (BPA), representing a class of organic pollutants, finds extensive applications in the pharmaceutical industry. However, its widespread use poses a significant hazard to both ecosystem integrity and human health. Advanced oxidation processes (AOPs) based on peroxymonosulfate (PMS) via heterogeneous catalysts are frequently proposed for treating persistent pollutants. In this study, the degradation performance of BPA in an oxidation system of PMS activated by transition metal sites anchored nitrogen-doped carbonaceous substrate (M-N-C) materials was investigated. As heterogeneous catalysts targeting the activation of peroxymonosulfate (PMS), M-N-C materials emerge as promising contenders poised to overcome the limitations encountered with traditional carbon materials, which often exhibit insufficient activity in the PMS activation process. Nevertheless, the amalgamation of metal sites during the synthesis process presents a formidable challenge to the structural design of M-N-C. Herein, employing ZIF-8 as the precursor of carbonaceous support, metal ions can readily penetrate the cage structure of the substrate, and the N-rich linkers serve as effective ligands for anchoring metal cations, thereby overcoming the awkward limitation. The research results of this study indicate BPA in water matrix can be effectively removed in the M-N-C/PMS system, in which the obtained nitrogen-rich ZIF-8-derived Cu-N-C presented excellent activity and stability on the PMS activation, as well as the outstanding resistance towards the variation of environmental factors. Moreover, the biological toxicity of BPA and its degradation intermediates were investigated via the Toxicity Estimation Software Tool (T.E.S.T.) based on the ECOSAR system.

Nonradical-dominated peroxymonosulfate activation by perylenetetracarboxylic acid nanosheet photocatalyst for efficient degradation of bisphenol a under visible-light irradiation

As a green, highly efficient, and sustainable technology, photocatalytic peroxymonosulfate (PMS) activation is a promising strategy for wastewater treatment. Moreover, the development of photocatalysts with excellent PMS activation performance is highly desirable for removing refractory organic contaminants from wastewater. Herein, perylenetetracarboxylic acid (PTA) nanosheets obtained using a facile method were explored as a highly efficient photocatalyst with a high PMS activation ability for bisphenol A (BPA) removal. Experimental results indicated that BPA can be removed within 16 min using PTA under optimal conditions. As confirmed through radical quenching, electron paramagnetic resonance spectroscopy, galvanic-oxidation-process experiments, and density functional theory calculations, photoinduced electrons and holes from PTA trigger PMS activation and thereby convert the reaction routes of BPA degradation from radical- to nonradical-dominated. The BPA degradation pathway was also studied using intermediate analysis and Fukui functions. Overall, the findings of this study shed light on organic semiconductor photocatalysts for nonradical-dominated PMS activation with regard to recalcitrant-organic-pollutant removal.

Intensify Mass Transfer and Molecular Oxygen Activation by Defect‐Bridged Asymmetric Catalytic Sites Toward Efficient Membrane‐Based Nanoconfined Catalysis

AbstractEfficient spontaneous molecular oxygen (O2) activation is expected in advanced oxidation processes. However, it remains a great challenge to promote the reactants adsorption and accelerate the interfacial electron transfer to boost the activation kinetic of O2. Herein, defect‐rich N‐doped reduced graphene oxide/CoFe2O4 (NGCF‐OV) membrane containing asymmetric Co‐OV‐Fe sites is prepared for O2 activation. The intrinsic catalytic activity is that the asymmetric Co‐OV‐Fe sites regulate the O─O bond length, promoting more and faster electron transfer to O2 for selectively producing 1O2. Meanwhile, the adjacent graphitic N sites help confine organics to the surface and thus greatly shorten the reaction distance of 1O2 and improve its utilization efficiency. The NGCF‐OV membrane demonstrates complete degradation of bisphenol A within a retention time of 86 ms, achieving a k‐value of 0.047 ms−1, which exceeds the performance of most Fenton‐like systems. This work provides new horizons for designing an efficient and stable catalytic membrane, enriching the domain of advanced wastewater treatment strategies.

Construction of La2O3/AgCl S-scheme heterojunction with interfacial chemical bond for efficient photocatalytic degradation of bisphenol A

The formation of interfacial chemical bonds in S-scheme heterostructure is a crucial factor to realize efficient interfacial charge transfer. High-energy mechanical ball-milling is an effective method to form interfacial chemical bonds. In this work, an S-scheme La2O3/AgCl heterojunction catalyst was designed and prepared by ball-milling method. XPS, FTIR and Raman measurements showed that La-Cl chemical bond was formed at the interface of La2O3 and AgCl and an S-scheme charge transfer path mechanism existed in the La2O3/AgCl composite. The results of electrochemistry, photo-electrochemistry, capture experiments, free radical measurement and EPR verified that the S-scheme heterojunction and the interfacial La-Cl bond significantly accelerated the charge transfer rate between La2O3 and AgCl, and enhanced the photocatalytic capability of the composite catalysts. The degradation rate of bisphenol A by La2O3/AgCl heterojunction composite (LA50) reached 99 % in 20 min, and it also had excellent anti-interference ability and cycling stability. The toxicity of the degradation intermediates of bisphenol A was much less than itself, as calculated by TEST simulation. This work provided a promising strategy for improving the performance of S-scheme heterojunction catalysts by introducing interfacial chemical bonds as charge transfer channels.

TiO2–Cu7S4 modified with a carbazole-based conjugated porous polymer for adsorption and photocatalytic degradation of bisphenol A

Adsorption-photocatalytic degradation of organic pollutants in water is an advantageous method for environmental purification. Herein, a feasible strategy is developed to construct a novel dual S-scheme heterojunctions Cu7S4–TiO2-conjugated polymer with a donor–acceptor structure. There are abundant adsorption active sites for adsorption in the porous structure of the composites, which can rapidly capture pollutants through hydrogen bonding and π-π interactions. In addition, the dual S-scheme heterojunctions effectively improve carrier separation while maintaining a strong redox ability. Thus, the optimized 1.5% CST-130 catalysts can adsorb 71% of 20 ppm BPA in 15 min and completely remove it within 30 min with high adsorption capacity and photodegradation efficiency. Therefore, this study provides a new inspiration for synergistic adsorption and degradation of BPA and the construction of dual S-scheme heterojunction.

Visible light driven Z-scheme α-MnO2 (1D)/Bi7O9I3 (2D) heterojunction photocatalyst for efficient degradation of bisphenol A in water

Z-scheme heterojunctions are gaining attention for their outstanding photocatalytic performance in degrading organic pollutants due to improved charge separation efficiency. In view of this, the present study is focused on the synthesis of novel 3D α-MnO2/Bi7O9I3 (MB) nanocomposites heterojunctions of varying α-MnO2 contents via facile in-situ chemical precipitation method at room temperature. Under optimum conditions, MB4 (comprising 485 mg of α-MnO2) exhibited exceptional performance, achieving about 97.5% of bisphenol A (BPA) degradation in 80 mins with a degradation rate constant of 0.08354 min−1. Such superior performance is attributed to efficient interfacial integration and charge separation, validated through various characterization techniques. Further, MB4 heterojunction facilitated Z-scheme electron-hole pair transfer and exhibited an augmented specific surface area. The active species involved in the degradation of BPA were identified as •O2– and •OH in scavenging experiments and supported by findings based on EPR. Additionally, degradation pathways and plausible BPA intermediates have been proposed based on LC-MS/MS studies. Furthermore, with an impressive mineralization rate (89.5%), the toxicity study unveiled less harmful intermediates than the parent compound BPA. MB4 photocatalyst also exhibited commendable stability, as evidenced by its studies based on five reuse cycles with 92.9% efficiency. In essence, visible-light-driven Z-scheme α-MnO2/Bi7O9I3 heterojunction photocatalyst offered a simple and sustainable approach for producing environmentally friendly materials, underscoring its potential in the removal of BPA in water and wastewater treatment.

Metagenomic landscape of sediments of river Ganga reveals microbial diversity, potential plastic and xenobiotic degradation enzymes

The Ganga is the largest river in India, serves as a lifeline for agriculture, drinking water, and religious rites. However, it became highly polluted due to the influx of industrial wastes and untreated sewages, leading to the decline of aquatic biodiversity. This study investigated the microbial diversity and plastic-xenobiotic degrading enzymes of six sediment metagenomes of river Ganga at Prayagraj (RDG, TSG, SDG) and Devprayag (KRG, BNG, BRG). The water quality parameters, higher values of BOD (1.8–3.7 ppm), COD (23–29.2 ppm) and organic carbon (0.18–0.51%) were recorded at Prayagraj. Comparative analysis of microbial community structure between Prayagraj and Devprayag revealed significant differences between Bacteroidetes and Firmicutes, which emerging as the predominant bacterial phyla across six sediment samples. Notably, their prevalence was highest in the BRG samples. Furthermore, 25 OTUs at genus level were consistent across all six samples. Alpha diversity exhibited minimal variation among samples, while beta diversity indicated an inverse relationship between species richness and diversity. Co-occurrence network analysis established that genera from the same and different groups of phyla show positive co-relations with each other. Thirteen plastic degrading enzymes, including Laccase, Alkane-1 monooxygenase and Alkane monooxygenase, were identified from six sediment metagenomes of river Ganga, which can degrade non-biodegradable plastic viz. Polyethylene, Polystyrene and Low-density Polyethelene. Further, 18 xenobiotic degradation enzymes were identified for the degradation of Bisphenol, Xylene, Toluene, Polycyclic aromatic hydrocarbon, Styrene, Atrazene and Dioxin etc. This is the first report on the identification of non-biodegradable plastic degrading enzymes from sediment metagenomes of river Ganga, India. The findings of this study would help in pollution abatement and sustainable management of riverine ecosystem.

Efficiency and mechanism of phosphoric acid modified biochar loaded nanoscale zero-valent iron activated peroxymonosulfate for the degradation of bisphenol A

The degradation efficiency of bisphenol A (BPA) using sulfate radical-based advanced oxidation processes still requires further improvement. Herein, we prepared phosphoric acid-modified biochar-supported nZVI (PBC/nZVI) through liquid-phase reduction. Under optimized conditions, including a PBC/nZVI dosage of 1.2 g/L, pH 9.0, and PMS concentration of 2.0 mmol/L, the BPA degradation rate reached up to 92.66 % within 60 min with the mineralization rate of 45.5 %. The presence of Cl−, HCO3− and CO32− promoted the degradation of BPA, while NO3− had minimal effect. Conversely, H2PO4− and humic acid exhibited varying degrees of inhibition. The degradation of BPA involved four reactive oxygen species (•OH, SO4•−, O2•−, and 1O2), with 1O2 playing a prominent role. The pathways of •OH-induced oxidation and SO4•−-induced hydroxylation were identified as the mechanisms through which BPA was degraded. These findings highlighted the potential of PBC/nZVI as a rapid and efficient material for BPA degradation.

Synthesis of a Cu-Al bimetallic oxide @ PVDF composite membrane for the degradation of bisphenol a via peroxydisulfate activation: Performance and mechanism

The presence of environmental endocrine-disrupting compounds, such as bisphenol A (BPA), in aquatic environments poses a significant risk to both ecological integrity and human health. Although CuO has been reported as a catalyst for activating peroxydisulfate (PDS) to degrade BPA, it exhibits certain limitations, including low catalytic efficiency, aggregation, and challenges in terms of separation and reusability. In this study, we developed a composite poly (vinylidene fluoride) (PVDF)-based membrane incorporating Cu-Al bimetallic oxide (Cu-Al) to address these issues. Results revealed that when employing the 7 wt% Cu-Al @ PVDF composite membrane to activate 1 mM PDS, approximately 95.3 % of BPA was degraded within 60 min in static experiments. Furthermore, this composite membrane exhibited remarkable efficacy across a broad pH range (3–11) and demonstrated excellent resistance against diverse anionic species. The removal process is proposed to be dominated by electron transfer between the composite membrane, PDS, and BPA via a two-step mechanism: Firstly, electron-rich Cu sites and oxygen vacancies were formed in the composite membrane, facilitating PDS adsorption and electron transfer from Cu sites to PDS to form a ligand complex; subsequently, BPA was adsorbed by the membrane and acted as an electron donor to be oxidized by the ligand complex. As a result, this system showed remarkable selectivity for degrading electron-rich organic compounds with ionization potentials below 9.0 eV. Overall, this work successfully fabricated a catalytic membrane exhibiting efficient PDS activation capability along with selective oxidation performance and facile reusability, making it highly promising for wastewater treatment.

Tuning interfacial oxygen vacancy level of bismuth oxybromide to enhance photocatalytic degradation of bisphenol A

Oxygen vacancies (OVs) have garnered significant interest for their role as active sites, enhancing the catalytic efficiency of various catalysts. Despite their widespread application in environmental purification processes, the generation of OVs conventionally depends on high-temperature conditions and strong reducing agents for the extraction of surface partial oxygen atoms from catalysts. In this work, bismuth oxybromide (BiOBr) nanosheets with varying levels of OVs were synthesized via a simple and effective solvothermal method. This novel method affords precise control over the conduction band (CB) and valence band (VB) positions of BiOBr. The presence of different OVs exhibited varying photocatalytic efficiencies in the degradation of bisphenol A (BPA) under visible light irradiation, with higher levels of OVs resulting in superior photocatalytic performance. Furthermore, radical scavenger experiments demonstrated that superoxide oxides (O2•−) and holes (h+) were the primary reactive oxygen species for BPA degradation. Additionally, BiOBr-OVs exhibited excellent anti-interference and stability in water matrices containing diverse inorganic anions and organic compounds. This work provides a simple and effective approach for the fine-regulating of catalysts through interfacial defect engineering, paving the way for their practical application in environmental decontamination.

High-efficiency metal-free electro-Fenton system on oxygenated graphene-based floating electrodes

Metal-free electro-Fenton (EF) are a promising technology for environmental remediation. This paper reports a novel EF modified with oxygenated graphene aerogel used as a floating electrode for efficient degradation of bisphenol A (BPA) through improved H2O2 yield combined with activation of hydroxyl radical (·OH) production. Impressively, the floating configuration of the electrodes allowed oxygen from the air to diffuse naturally into the reaction interface, reducing additional aeration energy consumption. The current efficiency of the floating system for H2O2 production was 40 times higher than the conventional vertical mode. The pollutant degradation trend exhibited a positive correlation with the ·OH production performance of the electrode. The modified catalyst system achieved the highest ·OH yield of 76.48 μM within 60 min, which was 2.72 times greater than that of the catalyst-free (28.10 μM) and 2.06 times higher than that of the unmodified catalyst (37.19 μM). Experiments and theoretical calculations indicated that the oxygen-containing functional groups introduced the graphene skeleton created new sites for in situ activation of electrogenerated H2O2, resulting in increased ·OH production. The primary activation sites were identified as the = O and –COOH groups, with the = O edges playing a particularly significant role. This system offers long-lasting stability and avoids secondary pollution, making it ideal for green environmental remediation compared to the traditional EF process.

UV and pulsed electron beam radiation for effective bisphenol A degradation

The paper presents the results of studying the efficiency of the bisphenol A transformation in water exposed to ultraviolet radiation and a high-energy-pulse-electron beam (e-beam). It has been shown that in both cases, degradation of dissolved bisphenol A occurs, accompanied by an increase in the absorption coefficient in the wavelength region of more than 300 nm. After exposure, products were recorded that fluoresced in the region of more than λ = 400 nm. The fluorescent transformation product of bisphenol A in water (λ = 425 nm) was maximum formatted after an KrCl excilamp irradiated, and under the action of an e-beam, the accumulation of this product was minimal. Under e-beam radiation (170 keV) the efficiency of bisphenol A (1 mM) removal reached 97%. The data obtained allow us to develop ideas about photolysis and radiolysis in natural water systems when knowledge about targeted and optimal conditions for the degradation of bisphenol A is needed.

Catalytic activation of persulfate by nanoscale zero-valent iron-derived supported boron-doped porous carbon for bisphenol A degradation.

In this study, boron-doped porous carbon materials (BCs) with high surface areas were synthesized employing coffee grounds as carbon source and sodium bicarbonate and boric acid as precursors; afterward, nanoscale zero-valent iron (nZVI) and BCs composites (denoted as nZVI@BCs) were further prepared through reduction of FeSO4 by NaBH4 along with stirring. The performance of the nZVI@BCs for activating persulfate (PS) was evaluated for the degradation of bisphenol A (BPA). In comparison with nZVI@Cs/PS, nZVI@BCs/PS could greatly promote the degradation and mineralization of BPA via both radical and non-radical pathways. On the one hand, electron spin resonance and radical quenching studies represented that •OH, SO4•-, and O2•- were mainly produced in the nZVI@BCs/PS system for BPA degradation. On the other hand, the open circuit voltages of nZVI@BCs and nZVI@Cs in different systems indicated that non-radical pathway still existed in our system. PS could grab the unstable unpaired electron on nZVI@BCs to form a carbon material surface-confined complex ([nZVI@BCs]*) with a high redox potential, then accelerate BPA removal efficiency via direct electron transfer. Furthermore, the performances and mechanisms for BPA degradation were examined by PS activation with nZVI@BC composites at various conditions including dosages of nZVI@BCs, BPA and PS, initially pH value, temperature, common anions, and humid acid. Therefore, this study provides a novel insight for development of high-performance carbon catalysts toward environmental remediation.

Rational fabrication of Z-scheme heterojunction ZnFe2O4-seed@TpTt-COF for the visible-light-driven photocatalytic degradation of bisphenol A in food waste leachate boosted by primitive humic acid

Herein, we proposed a method by pre-embedding organic covalent organic framework TpTt-COF(TpTt) (consisting of the electron donor 1,3,5-triazine-2,4,6-triamine (Tt) and electron acceptor 2,4,6-triformylphloroglucinol (Tp) aldehyde) within inorganic ZnFe2O4 core to serve as seed for the in-situ grafting of organic TpTt shell tightly. The as-formed ZnFe2O4-seed@TpTt-COF (Z-S@TpTt) core–shell structure exhibited visible-light-driven photocatalytic degradation of BPA effectively. This may stem from the rationally tuned energy band structure of ZnFe2O4-seed via TpTt pre-anchoring, thus enabled a Z-scheme electron transfer way within the heterojunction to broaden the light adsorption, accelerate the charge transfer and maintain their thermodynamic redox capacity. More strikingly, humic acid (HA) in the actual wastewater (food waste leachate (FWL), where BPA highly frequently presented) could even boost the photocatalytic degradation of BPA. Comprehensive characterizations and DFT calculations revealed that HA acts as a critical “electron shuttle” to further promote the separation of electron-hole pairs via the formation of an EDA complex with the Z-S@TpTt. The gathered electrons on CB of ZnFe2O4-seed and holes on VB of TpTt may generate more •O2– and 1O2, thus the improved performance of Z-S@TpTt core–shell heterojunction in BPA degradation was achieved. Besides the promoted catalytical activity, the convenient separation ability and extraordinary chemical/thermal stability inherited from the magnetic core and the COF shell also enabled robust reuse of Z-S@TpTt heterojunction in FWL. All of these properties endowed Z-S@TpTt heterojunction with the practical application potential to remove BPA in an economical and environment-friendly way, which is also compatible with the “waste control by waste” strategy today.
