Direct In Situ Polymer Modification of Titania Nanomaterial Surfaces via UV‐irradiated Radical Polymerization

Polymer modification of titania nanomaterials can provide media dispersibility and various functionalities onto the titania surface. Herein, we report the direct in situ polymer modification of the surface of titania nanotubes (TNTs) and titania nanoparticles (TNPs) via ultraviolet (UV)‐irradiated radical polymerization without any pretreatment of titania. The resulting polymer‐modified TNTs and TNPs dispersed well in solvents. The characterization of the products using various techniques including Fourier transform infrared spectroscopy, thermogravimetric analysis, and scanning electron microscopy–energy dispersive X‐ray spectroscopy confirmed the successful modification of the TNT and TNP surfaces by the polymers produced via UV‐irradiated radical polymerization. The polymers on the titania surface were isolated by dissolving titania using hydrofluoric acid and analyzed by means of size exclusion chromatography and matrix‐assisted laser desorption/ionization‐time of flight‐mass spectrometry. The polymer‐modified TNTs and TNPs maintained their photocatalytic activity in dye degradation under UV irradiation. Moreover, glycopolymer‐modified TNTs were successfully prepared using the UV‐irradiated polymerization system. The glycopolymer retained its lectin biding affinity on the TNT surface.

The synthesis of stabilized Ag NPs was used for ultra-sensitive and selective detection of Hg2+ ions in aqueous medium were monitored by Uv–visible spectrometer and naked eyes with a lowest limit of detection (LOD) 7 nM. The photo-catalytic degradation of methyl orange (MO) by utilizing Ag NPs as nano-catalyst exhibits a potential degradation within a study period of 180 min. Concluding that, facile and cost effective green synthesis of NCMH capped Ag NPs possess excellent reducing ability towards the selective detection of Hg2+ ions along with photo-catalytic degradation of MO dye. These true findings detached an innovative pathway of Ag NPs towards the reactivity against the catalytic activity of dye degradation and selective sensing of Hg2+ ions. Thus it paves the way for extensive range of novel potential applications of Ag NPs in various environment friendly approaches of sensitive and analytical protocol in the future.

Dye degradation activity of biogenically synthesized Cu/Fe/Ag trimetallic nanoparticles

Abstract Over the past few decades, nanotechnology has gained momentum because of its potential to create a safer and healthier living environment using eco-friendly approaches. This study describes a safer, more dependable, and ecologically friendly technique of biologically synthesizing Cu/Fe/Ag trimetallic nanoparticles (NPs) using an aqueous leaf extract of Catharanthus roseus as the reducing and stabilizing agent. The synthesized trimetallic NPs were characterized by scanning electron microscope, Fourier transform infrared, dynamic light scattering, and ultraviolet–visible analysis and were evaluated for their potential applications, which included antioxidant properties and catalytic dye degradation. The result suggests that the antioxidant properties of Cu/Fe/Ag NPs are more significant than those of ascorbic acid, a known antioxidant, at lower doses (10 µg·ml−1) while a higher dose of 1,000 µg·ml−1 gives a 69.81% scavenging activity. The impact of Cu/Fe/Ag trimetallic NPs on the catalytic degradation of hazardous dyes such as phenol red (PR) and eosin yellow (EY) was also studied in this work. For PR and EY, the corresponding percentages of degradation were 76% and 48.6%, respectively.

The current research work reports on binary Nickel oxide-Zinc oxide (NiO-ZnO) and Nickel oxide-Cerium oxide (NiO-CeO2) nanocomposites synthesis by facile single step in-situ thermal decomposition method and its applications. The structural and morphological studies were examined using various characterization techniques like IR, UV-DRS, XRD and SEM with EDAX studies. The IR bands at 545-533 cm−1 corresponds to M-O stretching vibration. The XRD studies confirms the structural pattern of NiO-ZnO and NiO-CeO2 nanocomposites. SEM with EDAX results reveal the structure, composition and purity of synthesized nanocomposites. The nanocomposites were employed as photocatalyst for degradation of methylene blue and methyl orange dyes and as a catalyst toward 4-nitrophenol reduction.

Sol-gel synthesized Cu/ZnS nanocomposites for photocatalytic dye degradation and antibacterial activity

Reduced Work Function in Anatase ⟨101⟩ TiO2 Films Self-Doped by O-Vacancy-Dependent Ti3+ Bonds Controlling the Photocatalytic Dye Degradation Performance.

TiO2 has the proven capability of catalytically decomposing pollutants under light illumination, thereby embracing potential applications in wastewater management. The photocatalytic dye degradation activity is largely controlled by the optical band gap that dictates the extent of electron-hole pair generation via photon absorption, and the recombination kinetics of charges. In this context, the material's work function governs how easily the charge carriers can be transferred at the dye-adsorbed photocatalytically active sites. Accordingly, nanocrystalline TiO2 thin films are grown in the anatase phase with ⟨101⟩ orientation, using RF magnetron sputtering at 200 °C. Besides studying the film's structural morphology, optical band gap, and elemental composition, the electronic properties are extensively investigated. The work function of the material was controlled by varying the O-vacancy-dependent Ti3+ bonding configuration in the network. It has been demonstrated how the photocatalytic methylene blue dye degradation activity of the nanocrystalline TiO2 films of predominantly the anatase phase improves on reducing the sputtering pressure during deposition. At a low deposition pressure of 20 mTorr, a low work function of ∼4.2 eV of the film, resulting from the formation of a Ti3+-bond through the O vacancies in the network, potentially increases its carrier lifetime and delivers the superior photocatalytic activity (∼82.7% dye degradation with a rate constant of k ∼ 0.0073 min-1) via silently facilitating fast electron transfer from the photocatalyst to the dye in the aqueous solution. The higher stoichiometric film prepared at p = 40 mTorr exhibits an inferior photocatalytic activity (∼20.4% dye degradation with a rate constant of k ∼ 0.0009 min-1), as retarded by its higher work function of ∼4.62 eV, despite retaining a relatively low band gap. Thus, without using any heterojunction or extrinsically doped photocatalyst, the dye degradation can be controlled simply by reducing the work function of nanocrystalline TiO2 thin films via controlling the O-vacancy-dependent Ti3+ bonding in its self-doped network.

Bio-capped multifunctional CuO nanoparticles via Knautia arvensis for dye removal, antibacterial and antifungal efficiency, and molecular docking

Copper oxide nanoparticles (CuONPs) synthesized using Knautia arvensis flower extract in an environmentally friendly and one-step procedure were characterized by UV–vis, FT-IR, SEM and DLS. The in vitro antibacterial and antifungal activities of CuONPs were determined using E. coli, S. aureus and A. niger. In silico antibacterial and antifungal evaluation of CuONPs were performed by molecular docking analysis using chitin deacetylase of A. niger, topoisomerase IV of E. coli and tyrosyl-tRNA synthetase of S. aureus. The best binding energy was determined using these microbial targets in molecular docking analyses and the antimicrobial mechanisms between the microorganism and the CuONP were elucidated. The degradation potential of Remazol brilliant blue R (RBBR) and Napthol blue black (NBB) dyes in the presence of CuONPs were investigated. The peak obtained at 289 nm as a result of UV–vis analysis revealed the presence of CuONPs. The spherical morphology of CuONPs and the particle size varying between 88–289 nm were visualized by SEM. DLS analysis pointed out the mean diameter of CuONPs was 189 nm along with the PDI value of 0.324. The 600 and 595 cm−1 vibrations attained in the FT-IR spectroscopy showed the presence of CuONPs. In addition, the presence of phenolic compounds found in the plant extract responsible for bio-capping of copper ions into CuONPs were enlightened by the FT-IR analysis. Dye degradation activity of CuONPs was found as 69% and 71% using NBB and RBBR at 50 °C in 90 min, respectively. Antifungal and antibacterial interactions of CuONPs with chitin deacetylase of A. niger, topoisomerase IV of E. coli and tyrosyl-tRNA synthetase of S. aureus were analyzed in order to reveal the antimicrobial mechanisms of CuONPs and it was found that CuONPs demonstrate significant interactions with those proteins with binding energies −7.25, −7.14 and −7.89 kcal mol−1, respectively.

Cu-chelated polydopamine nanozymes with laccase-like activity for photothermal catalytic degradation of dyes

The industrial applications of enzymes are usually hindered by the high production cost, intricate reusability, and low stability in terms of thermal, pH, salt, and storage. Therefore, the de novo design of nanozymes that possess the enzyme mimicking biocatalytic functions sheds new light on this field. Here, we propose a facile one-pot synthesis approach to construct Cu-chelated polydopamine nanozymes (PDA-Cu NPs) that can not only catalyze the chromogenic reaction of 2,4-dichlorophenol (2,4-DP) and 4-aminoantipyrine (4-AP), but also present enhanced photothermal catalytic degradation for typical textile dyes. Compared with natural laccase, the designed mimic has higher affinity to the substrate of 2,4-DP with Km of 0.13 mM. Interestingly, PDA-Cu nanoparticles are stable under extreme conditions (temperature, ionic strength, storage), are reusable for 6 cycles with 97 % activity, and exhibit superior substrate universality. Furthermore, PDA-Cu nanozymes show a remarkable acceleration of the catalytic degradation of dyes, malachite green (MG) and methylene blue (MB), under near-infrared (NIR) laser irradiation. These findings offer a promising paradigm on developing novel nanozymes for biomedicine, catalysis, and environmental engineering.

Enhanced Visible Light Photocatalytic Activity of Exfoliated Boron‐TiO2 Composite for Degradation of Rhodamine B and Nitrogen Fixation

AbstractThe design of an efficient, recyclable, visible light photocatalytic system was examined as a viable new green way to address environmental challenges such as removal of pollutants from wastewater and N2 fixation. The exfoliated boron (Bexf)‐Titanium oxide (TiO2) composite visible light active photocatalysts were successfully constructed via a simple wet chemical method by utilizing acetone as a solvent. The composite was evaluated for the photodegradation of Rhodamine B (RhB) dye and reduction of N2, which exhibits improved photocatalytic activity for degradation of RhB as well as for reduction of N2. Experiments with different quenchers indicate that the photogenerated superoxide radical anion (O2⋅−) plays a significant role in the degradation of RhB as well as for N2 reduction reactions. The composite catalyst shows good photostability and there is no significant reduction of the catalyst activity for dye degradation up to 4 cycles of reaction. This work affords a significant view into the design of reusable TiO2 composite materials for photocatalytic RhB degradation and nitrogen fixation.
