Improving Triethylamine-Sensing Performance of WO3 Nanoplates through In Situ Heterojunction Construction.

Surface engineering techniques can be used to develop high-performance gas sensing materials and advance the development of sensors. In this study, we improved the gas sensing performance of two-dimensional (2D) WO3 nanoplates by combining surface Zn modification and the in situ formation of ZnWO4/WO3 heterojunctions. Introducing Zn atoms by surface modification can reconstruct the atomic surface of 2D WO3 nanoplates, creating additional active sites. This allowed for the preparation of various types of ZnWO4/WO3 heterojunctions on the surface of the WO3 nanoplates, which improved the selectivity and sensitivity to the target gas triethylamine. The sensor exhibited good gas sensing performance for triethylamine even at low operating temperatures and strongly resisted humidity changes. The ZnWO4/WO3 material we prepared demonstrated a nearly threefold improvement in the triethylamine (TEA) response, with a gas sensing responsivity of 40.75 for 10 ppm of TEA at 250 °C. The sensor based on ZnWO4/WO3 has a limit of detection (LOD) for TEA of 200 ppb in practical measurements (its theoretical LOD is even as low as 31 ppb). The method of growing ZnWO4 on the surface of WO3 nanoplates using surface modification techniques to form surface heterojunctions differs from ordinary composites. The results suggest that the in situ construction of surface heterojunctions using surface engineering strategies, such as in situ modifying, is a practical approach to enhance the gas sensing properties and resistance to the humidity changes of metal oxide materials.

Interface Engineering Induced Multi-Scale Self-Assembly NiFe-LDH Heterostructures for High-Performance Water Electrolysis.

Confronted with the pressing issue of energy scarcity, the development of an economical and potent bifunctional catalyst is of paramount importance. We adopt an interface engineering strategy to modify the surface of NiFe-LDH nanoplates with O2 plasma treatment. This process enhances the local electric field of NiFe-LDH, resulting in the formation of a self-assembled polycrystalline nanowire array on the nanoplate surface. After O2 plasma treatment for 30 min, the NiFe-LDH-P30 not only formed a heterostructure with rough surface, but also regulated the exposure of crystal surfaces. Due to the strong interface coupling between the self-assembled 3D nanoflowers, 2D nanoplates and 1D nanowires, the NiFe-LDH-P30 exhibits an excellent structural stability. Moreover, it demonstrated exceptional HER and OER activities in alkaline condition, achieving a low overpotentials of 154 mV and 242 mV at 10 mA cm-2, respectively. Furthermore, NiFe-LDH-P30 as the dual-electrode material for the cathode and anode in the process of water splitting results in a low voltage of 1.63 V at a current density of 10 mA cm-2. Through the strategic application of interface engineering, this work has pioneered a novel approach to the creation of transition metal-based electrocatalysts, which is benefit to a range of practical energy applications.

A S-scheme 0D/2D heterojunction formed by decorating Cd0.5Zn0.5S nanoparticles on Cu2MoS4 plates for efficient photocatalytic hydrogen generation

Rationally designing a Step-scheme (S-scheme) hetero-structured photocatalyst with high redox capability and separation efficiency of photoinduced carriers is considered as an attractive approach to address the shortcomings of single component and traditional hetero-structured photocatalyst. Herein, enlightened by the predictions of density functional theory (DFT), a unique S-scheme heterojunction photocatalyst was successfully fabricated by incorporating zero-dimensional (0D) Cd0.5Zn0.5S (CZS) on two-dimensional (2D) lamellar Cu2MoS4 (CMS) plates via a facile coprecipitation method, which substantially enhances the photocatalytic activity for hydrogen (H2) generation. CZS nanoparticles deposited on the surface of CMS nanoplates play a crucial role in creating highly intimate heterojunction interfaces and abundant exposed reaction sites, laying the foundation for improved photocatalytic performance. Furthermore, the significant difference in Fermi levels and band structures between CZS and CMS result in the formation of the internal electric field (IEF) and energy band bending at the interface of the heterojunction. This S-scheme charge transfer path enables 0D/2D CZS/CMS heterojunction possesses an exceptional capacity to maintain the robust redox potential and boosts the separation efficiency of light-induced carriers, as verified by DFT calculations and energy band structure analyses. As expected, the optimal heterojunction exhibits a satisfactory H2 generation rate of 13.1 mmol·g-1·h−1, which is nearly 7.7-fold higher than that of individual CZS. This study is expected to inspire the design of morphology-controlled hetero-structured photocatalyst with S-scheme charge transfer route for photocatalytic H2 generation.

Oxidation Tuned Cu 1.94 S Nanostructures for Ultrafast Charge and Discharge

Morphological control is an effective approach to enhance the rate performance of nanostructured electrode materials, offering a promising solution for alleviating energy concerns. We have utilized a seed-mediated growth method to synthesize hexagonal djurleite (Cu 1.94 S) nanoplates and nanoflowers under N 2 and air, respectively. The influence of the morphology on the ion interaction has been investigated in the storage process through half-cell electrochemical energy storage. Cu 1.94 S nanoplates performed a higher specific capacity of 193 mAh g −1 at a high rate of 8 A g −1 than nanoflowers and showed excellent cycle stability over 4,000 cycles with capacity retention of 80.8%. The relationship between morphology and electrochemical performance was explored through further electrochemical characterization. It is found that the stacking of hexagonal surfaces of nanoplates increases the contact area of the electrode material and reduced resistance, leading to faster ion migration and a more complete redox process, ultimately contributing to a higher specific capacity. Our study has enhanced the understanding of structure–property relationships for electrode material, providing an insightful approach for the preparation of electrode materials suitable for ultrafast charge and discharge.

Popcorn-stick-like NH2-UiO-66/TiO2 nanotube nanocomposites toward optimized photocatalytic carbon oxidation with nitrogen dioxide

Developing photocatalytic technologies for pollutants removal with high harmless product selectivity is a significant challenge. Construction and optimization of nanocomposites junction with appropriate band alignments is an effective method for achieving this objective. Herein, a unique popcorn-stick-like NH2-UiO-66/TiO2 nanotube nanocomposites with staggered band alignment is fabricated. The small metal organic frameworks (MOFs) particles with diameters around 20 nm are uniformly dispersed on the surface of TiO2 nanoplates, creating a popcorn-stick-like structure. The resulting as-synthesized nanocomposites photocatalysts show distinguished photocatalytic activity for simultaneous removal of carbon particles and nitrogen dioxide with 100% NO2 conversion and 99% N2 selectivity, about 3.9 times higher than that of pristine TiO2. The significant enhancement is attributed to the rapid charge separation and transfer in TiO2 and NH2-UiO-66 interface and the visible light absorption. The enhanced charge transfer follows double charge transfer mechanism, which is confirmed by surface photovoltage spectroscopy, photoluminescence, transient photocurrent measurements, and electrochemical impedance spectroscopy. This study demonstrates the potential for the simultaneously removal of two pollutants using the composite of TiO2 and MOF materials with high surface area and visible light absorption ability, thereby providing the possible applications of NH2-UiO-66/TiO2 composites in environmental remediation including air purification and wastewater treatment.

Low-dimensional heterostructures of tin nanoparticle-decorated Bi2Te3 nanoplates for reducing lattice thermal conductivity

Low-dimensional materials such as nanoplates exhibit unique properties. Among them, thermoelectric materials are one of the most beneficial because they allow the application of a low-dimensional effect to reduce the lattice thermal conductivity. In this study, low-dimensional heterostructures of nanoparticle-decorated nanoplates were prepared to further reduce lattice thermal conductivity. Single-crystalline bismuth telluride (Bi2Te3) nanoplates with regular hexagonal shapes were fabricated by solvothermal synthesis. Subsequently, tin nanoparticles were decorated on the surface of the Bi2Te3 nanoplates via electroless plating with various concentrations of Sn precursor (SnCl2). Surface morphology and composition analyses indicated the presence of Sn on the nanoplate surface. To evaluate the original thermal properties of the nanoplates and not those of the fused nanoplates, polycrystalline film-formed nanoplates were prepared by pressing at 300 K under a pressure of 0.45 GPa. The in-plane lattice thermal conductivity of the tin nanoparticle-decorated nanoplates decreased with increasing SnCl2 concentration. At a SnCl2 concentration of 90 mM, the lattice thermal conductivity is 1.3 W/(m·K), which is approximately 30 % lower than that of the nanoplates without electroless plating. This indicates that the deposition of tin on the nanoplate surface reduces the phonon flow owing to phonon scattering. These findings provide a reference for controlling thermal properties of low-dimensional heterostructured materials.

Visible Light Locking in Mineral-Based Composite Phase Change Materials Enabling High Photothermal Conversion and Storage.

Fully stimulating the capacity of light-driven phase change materials (PCMs) for efficient capture, conversion, and storage solar energy requires an ingenious combination of PCMs, supporting structural materials, and photothermal materials, therefore motivating the synergistic effects between the components. Herein, this work thoroughly explores the interaction forces between PCMs and supporting structural materials and the synergy between PCMs and photothermal materials in photothermal conversion. Rejoicingly, when capitalizing on the prepared directional channel structure of hierarchically porous composite aerogel (PEPG) as a supporting structural material, a superior paraffin wax (PW) encapsulation rate of 85.11% is achieved, and the prepared PEPG2-PW has a high phase change enthalpy of 182.9 J/g. The van der Waals force and Lewis acid-base action between PEPG and PW molecules reveal the excellent stabilities of PEPG-PW. More importantly, the PEPG2-PW has an ultrahigh photothermal conversion efficiency of 95.2% under 1 sun irradiation and durability. Most importantly, the COMSOL Multiphysics software calculations demonstrate that transparent PW can anchor sunlight on the surface of graphite nanoplates, converting it into heat by enhancing the loss of graphite backbone lattice vibrations, and the accumulated heat is then stored in molten PW. This work provides some design principles for high-efficiency solar-thermal conversion materials.

Development Aramid Nanofiber‐ and Pentaerythritol‐Grafted Graphene Nanoplate‐Based High‐Performance Thermally Conductive Composites

AbstractA novel filler surface treatment is employed to produce thermally conductive composites using an aramid nanofiber (ANF) and pentaerythritol (PER) grafted onto the surface of graphite nanoplates (GnP). The resulting composite exhibits exceptional properties, including a high through‐plane thermal conductivity of 4 W mK−1, a high tensile strength of 163.58 MPa, and an improved flame retardancy. When the composite is applicated in central processing unit (CPU), the efficient thermal management performance is achieved with a decreased operating temperature of 12 °C. The ANF/GnP–PERANF composites are promising for enhancing thermal management in electric devices. The manufactured ANF composites will open new avenues for advancing the development of next‐generation thermal management systems.

Constructing BiOCl nanosheets on BiOBr nanoplates by NH4Cl etching with enhanced photocatalytic H2O2 production performance

BiOCl/BiOBr heterojunction was designed by NH4Cl etching method to enhance photocatalytic H2O2 production. BiOCl nanosheeets were firmly in-situ generated on the surface of BiOBr nanoplates after treating BiOBr with NH4Cl, forming an effective Z-type heterojunction. The photocatalytic system can achieve a considerable productivity of H2O2 to 2604.11 μmol/g/h under simulated solar irradiation, which can be explained that BiOCl/BiOBr heterojunction improve the separation and migration ability of photocarriers, thus accelerating the photocatalytic H2O2 production process.

Deterioration behavior of graphene-modified epoxy-primer-coated aluminum alloy in a UVA acidic alternation immersion environment

The modification of epoxy primers with graphene can significantly improve their anticorrosion properties and reduce environmental pollution. In this study, the modified epoxy primers with different graphene contents were prepared and tested in a UVA acidic alternation immersion environment. The deterioration characteristics under different corrosion times were analyzed in terms of their microscopic morphology, electrochemical characteristics, and molecular structure. It was shown that graphene nanoplates can impede the penetration of corrosive media, promote the cathodic protection of fillers, and easily cross-link with amino radicals to improve the binding force at the interface. The coated surface of graphene nanoplates with a content of 1.0 wt% was flatter than those with a content of 0.5 wt% and 2.0 wt%. After corrosion, the roughness of the surfaces all increased significantly. Especially, the coatings with graphene contents of 0.5 wt% increased nearly three times. And the impedance improvement of the coatings with graphene contents of 0.5 wt% and 1.0 wt% is more significant, both reaching more than 6 × 1011 Ω·cm2. The most obvious corrosion inhibiting effect was the coatings with a graphene content of 1.0% wt.

Construction and regulation of molybdenum carbide/carbon hollow microtube composite and its supercapacitive behaviors

Crystal structure has an important effect on electrochemical performance. In this work, the molybdenum carbide/carbon hollow microtube (MoC/CHMT) composite is synthesized via carbonation of polydopamine encapsuled Mo-MOF material. Additionally, the crystal structure of molybdenum carbide in composite is controlled by adjusting the mass of dopamine in polymerization. The optimized MoC/CHMT shows the hollow microtubes morphology with the microtube diameter about 600–1100 nm and microtube wall thickness of 230–400 nm, constructed by small molybdenum carbide nanoparticles (about 1.2–1.5 nm) on the surface of nanoplates with thickness of ∼17 nm. Moreover, it could achieve a high specific capacitance of 513.5 F g−1 at a current density of 0.5 A g−1. The constructed YP50//MoC/CHMT device exhibits a maximum energy density of 17.5 Wh kg−1.

Surface Ligands Dictate the Mechanical Properties of Inorganic Nanomaterials.

The ability for organic surface chemistry to influence the properties of inorganic nanomaterials is appreciated in some instances but is poorly understood in terms of mechanical behavior. Here we demonstrate that the global mechanical strength of a silver nanoplate can be modulated according to the local binding enthalpy of its surface ligands. A continuum-based core-shell model for nanoplate deformation shows that the interior of a particle retains bulk-like properties while the surface shell has yield strength values that depend on surface chemistry. Electron diffraction experiments reveal that, relative to the core, atoms at the nanoplate surface undergo lattice expansion and disordering directly related to the coordinating strength of the surface ligand. As a result, plastic deformation of the shell is more difficult, leading to an enhancement of the global mechanical strength of the plate. These results demonstrate a size-dependent coupling between chemistry and mechanics at the nanoscale.

Controllable synthesis of two-dimensional magnetic FeS nanoplates with high Curie temperature and unique magnetotransport properties

The discovery of magnetic two-dimensional materials has ignited intensive research interest for the potential development in innovative spintronic devices. Herein, ultrathin FeS nanoplates with various thicknesses are obtained through a chemical vapor deposition method and their magnetic properties are comprehensively studied. The obtained material displays trapezoidal shapes on SiO2/Si substrate and triangular shapes on large-area WSe2 nanosheets. A high degree of crystallinity and flat surface of FeS nanoplates are verified by Raman spectra, X-ray photoelectron spectroscopy analysis, X-ray diffraction patterns and annular dark-field aberration-corrected scanning transmission electron microscopy. Then magneto-transport studies illustrate that the resistance displays a bowtie shape after sweeping a full cycle of magnetic fields, which shows a decreasing trend with an increasing temperature but persists to 300 K. Thickness-dependent analysis demonstrates that the bowtie shape of resistance gradually reduces as the thickness of nanoplates increases. Angle-dependent measurements reveal that resistance shows apparent anisotropic properties. At last, vibrating sample magnetometer results show as-grown FeS nanoplates feature magnetism at room temperature. Our study demonstrates that FeS nanoplates grown by chemical vapor deposition methods provide an ideal system to research magnetic properties at the two-dimensional limit, providing new opportunities for the next-generation spintronic devices.

Developing efficient CuO nanoplate/ZnO nanoparticle hybrid photocatalysts for methylene blue degradation under visible light.

CuO/ZnO nanocomposites with different components can overcome the drawbacks of previously used photocatalysts owing to their promotion in charge separation and transportation, light absorption, and the photo-oxidation of dyes. In this study, CuO nanoplates were synthesized by the hydrothermal method, while ZnO nanoparticles were fabricated by the precipitation method. A series of CuO/ZnO nanocomposites with different ZnO-to-CuO weight ratios, namely, 2 : 8, 4 : 6, 5 : 5, 6 : 4, and 8 : 2 were obtained via a mixing process. X-ray diffraction patterns confirmed the presence of hexagonal wurtzite ZnO and monoclinic CuO in the synthesized CuO/ZnO nanocomposites. Scanning electron microscopy showed the dispersion of ZnO nanoparticles on the surface of CuO nanoplates. Ultraviolet-visible absorption spectra exhibited a slight red-shift in the absorption edge of binary oxides relative to pure ZnO or CuO. All samples were employed for the photocatalytic degradation of methylene blue (MB) under visible light irradiation. The composite samples exhibited enhanced photocatalytic performance compared with pristine CuO or ZnO. This study aimed to examine the effect of the ZnO-to-CuO weight ratio on their photocatalytic performance. The results indicated that among all the synthesized nanocomposites and pristine oxides, the nanocomposite with ZnO and CuO in a proportion of 4 : 6 shows the highest photodegradation activity for the removal of MB with 93% MB photodegraded within 60 min at an initial MB concentration of 5 ppm. The photocatalytic kinetic data were described well by the pseudo-first-order model with a high correlation coefficient of 0.95. The photocatalytic mechanism of the mixed metal oxide was proposed and discussed in detail. The photodegradation characteristic of CuO/ZnO nanostructures is valuable for methylene blue degradation from aqueous solutions as well as environmental purification in various fields.

Catechol exerts an in situ surface oxygen vacancy effect on BiOI: an innovative signal transduction mode for cathodic photoelectrochemistry.

Cathodic photoelectrochemistry, a research hotspot in state-of-art bioassays, is generally circumscribed by its monotonous signal transduction tactic of photoinduced electron transfer (PET) mechanism, which significantly narrows the scope of its applications. In this study, we reveal the surface oxygen vacancy (VO) formation elicited by the spontaneous coordination of catechol (CA) onto the surface of BiOI nanoplates for the innovative operation of the cathodic PEC signal transduction tactic. The in situ-generated VO functions as a carrier separation center to efficiently promote photocurrent generation. Taking tyrosinase (TYR) and Escherichia coli O157:H7 (E. coli O157:H7) as model targets, the established signal transduction tactic was validated as efficient and sensitive for the detection of the two targets with linear ranges from 1.0 × 10-4 to 1.0 U mL-1 and 5.0 to 1.0 × 106 CFU mL-1, respectively. Low-detection limits of 1.0 × 10-4 U mL-1 and 3.0 CFU mL-1 were achieved for TYR and E. coli O157:H7, respectively. This study opens up a new perspective of in situ generated surface VO on semiconductors, which underlies an innovative PEC signal transduction mechanism with convincing analytical performance. Hopefully, it might encourage more explorations of new methodologies for introducing surface vacancies with exquisite applications.

Van der Waals Interaction-Driven Self-Assembly of V2O5 Nanoplates and MXene for High-Performing Zinc-Ion Batteries by Suppressing Vanadium Dissolution.

Aqueous zinc-ion batteries (AZIBs) are attractive energy storage devices that benefit from improved safety and negligible environmental impact. The V2O5-based cathodes are highly promising, but the dissolution of vanadium is one of the major challenges in realizing their stable performance in AZIBs. Herein, we design a Ti3C2Tx MXene layer on the surface of V2O5 nanoplates (VPMX) through a van der Waals self-assembly approach for suppressing vanadium dissolution during an electrochemical process for greatly boosting the zinc-ion storage performance. Unlike conventional V2O5/C composites, we demonstrate that the VPMX hybrids offer three distinguishable features for achieving high-performance AZIBs: (i) the MXene layer on cathode surface maintains structural integrity and suppresses V dissolution; (ii) the heterointerface between V2O5 and MXene enables improved host electrochemical kinetics; (iii) reduced electrostatic repulsion exists among host layers owing to the lubricating water molecules in the VPMX cathode, facilitating interfacial Zn2+ diffusion. As a result, the as-made VPMX cathode shows a long-term cycling stability over 5000 cycles, surpassing other reported V2O5-based materials. Especially, we find that the heterointerface between V2O5 and MXene and lubricated water molecules in the host can achieve an enhanced rate capability (243.6 mAh g-1 at 5.0 A g-1) for AZIBs.

In Situ Construction of WO3/Bi2WO6 Heterogeneous Materials for Advanced Photocatalytic Activity in Degradation of Tetracycline

AbstractThe composite photocatalyst composed of WO3 and Bi2WO6 can play the synergistic effect between the two individual components. Herein, a WO3/Bi2WO6 heterogeneous material with high quality interface has been synthesized via situ growing Bi2WO6 directly on the surface of WO3 nanoplates. The photocatalytic degradation efficiency of tetracycline (TC) for BWO‐3 reaches ≈92%, which is much higher than that of WO3 (≈27%) due to the coupling effect of WO3 and Bi2WO6. Electrochemical impedance and photocurrent measurements prove that WO3/Bi2WO6 heterogeneous material has decreased carriers’ transfer resistance and higher photocurrent density, which endows its improved photocatalytic performance. Also, the radical trapping experiment proves that superoxide radical has great impacts on the degradation of TC. This work provides an efficient method for developing photocatalysts with excellent performance.

Facile in-situ construction of plate-on-plate structured Bi2MoO6/BiOI Z-scheme heterojunctions enriched with oxygen vacancies for highly efficient photocatalytic performances

Novel Bi2MoO6/BiOI plate-on-plate porous Z-scheme heterostructures (BMI PHs) enriched with oxygen vacancies (OVs) were synthesized via an ion exchange approach accompanied by the in-situ growth process. A possible formation process of BMI PHs was studied systemically, depicting the procedures of erosion and growth of Bi2MoO6 nanoplates (NPs) in-situ on the surface of BiOI NPs, indicating the crucial role of Bi2MoO6 in influencing the microstructure and photocatalytic ability of BMI PHs. BMI PHs exhibited a significantly improved visible-light photocatalytic performance in comparison with BiOI and Bi2MoO6 towards the degradation of Rhodamine B (RhB) and inactivation of Pseudomonas aeruginosa (P. aeruginosa), which can be ascribed to the construction of Z-scheme heterojunction and abundant OVs, resulting in the accelerated separation of photoinduced charge carriers and more powerful redox capacity. Among them, BMI-0.5 can remove almost all RhB and P. aeruginosa within 60 min, presenting the strongest photocatalytic activity. The photocatalytic mechanism was investigated based on the radicals trapping and electron spin resonance (ESR) tests together with the first-principle theoretical calculation, validating the dominated roles of ∙OH, ∙O2– and h+ in the photocatalytic reaction. These results provide a new strategy to develop Z-scheme heterojunction photocatalysts with promising utilization prospect in environmental remediation.

One dimensional ZnWO4 nanorods coupled with WO3 nanoplates heterojunction composite for efficient photocatalytic and photoelectrochemical activity

In this study, we report a novel semiconductor heterojunction of ZnWO4/WO3 composite successfully constructed through one-pot facile and eco-friendly in situ hydrothermal synthesis. The structural, morphological and photophysical property of ZnWO4/WO3 composite were investigated by powder X-ray diffraction (XRD), Raman spectrum, scanning electron microscope (SEM), high resolution transmission electron microscope (HRTEM), photoluminescence (PL) and transient photocurrent response. The morphological analysis indicated that ZnWO4 nanorods are well distributed on the surface of WO3 nanoplates. The ZnWO4/WO3 heterojunction composite possess strong light absorption in the visible region. To explore the photocatalytic activity of the prepared ZnWO4/WO3 heterojunction composite methylene blue (MB) was chosen as organic dye to assess the degradation ability of composite under visible light treatment. ZnWO4/WO3 heterojunction composite showed remarkable photocatalytic activity than that of pristine ZnWO4 and WO3. The elevated photocatalytic activity is attributed to the formation of heterojunction interface between WO3 and ZnWO4, leading to effective transfer and separation of photogenerated carriers in heterojunction. A plausible mechanism for the superior photocatalytic degradation over ZnWO4/WO3 heterojunction composites was also proposed.

Sonochemical synthesis and characterization of Ag/AgCl/Bi2MoO6 as visible-light-driven photocatalyst for rhodamine B degradation

Heterostructure Ag/AgCl/Bi2MoO6 nanocomposites as visible-light-driven photocatalyst for rhodamine B (RhB) degradation were prepared by precipitation and sonochemical-assisted deposition method. The phase, morphology, oxidation state of element and optical properties of heterostructure Ag/AgCl/Bi2MoO6 nanocomposites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and UV-visible spectroscopy. In this research, the pure sample prepared by simple hydrothermal method was orthorhombic phase of Bi2MoO6 nanoplates with smooth surfaces. Upon being loaded with Ag/AgCl by sonochemical-assisted deposition method, AgCl and Ag nanoparticles were deposited on the surface of Bi2MoO6 nanoplates. The UV-visible spectra of Ag/AgCl/Bi2MoO6 nanocomposites show visible light absorption higher than pure Bi2MoO6 nanoplates. The enhanced photocatalytic efficiency of Ag/AgCl/Bi2MoO6 nanocomposites was investigated through rhodamine B (RhB) degradation under visible light irradiation and compared with those of the Bi2MoO6 nanoplates and AgCl/Bi2MoO6 nanocomposites. The photocatalytic efficiency of heterostructure Ag/AgCl/Bi2MoO6 nanocomposites in degrading RhB under visible light irradiation is higher than those of Bi2MoO6 nanoplates and AgCl/Bi2MoO6 nanocomposites. The photocatalytic efficiency of Ag/AgCl/Bi2MoO6 nanocomposites in degrading RhB is 99.70% under visible light irradiation within 30 min.
