Ultrathin structures have gained more and more attention due to their large surface area and abundant reactive sites, which are beneficial for the improvement of performances. Herein, we report an ultrathin Bi 2 MoO 6 synthesized by a simple mannitol-assisted hydrothermal method for the first time. The as-synthesized ultrathin Bi 2 MoO 6 exhibits highly selective adsorption efficiency toward various positively charged organic dyes. Moreover, the ultrathin Bi 2 MoO 6 displays enhanced photocatalytic activity in comparison with pristine Bi 2 MoO 6 . Systematic photoelectrochemical measurements reveal that the higher separation efficiency of photogenerated carriers takes responsibility for the improved photocatalytic performance. This work provides a simple path for designing ultrathin nanoarchitectures and widening application for these ultrathin materials.

In this work, we mainly investigate the adsorption properties of the simulated single and mixture wastewaters over porous Bi 2 MoO 6 @BiOCl@MOF-199 (BMO@BOC@MOF-199), including methylene blue (MB), rhodamine blue (RhB), methyl orange (MO) and chromium (VI). It is found that BMO@BOC@MOF-199 has a high adsorption capacity for MB, but a poor adsorption capacity for MO. Specifically, for single MB solution, 67%, 80% and 96% of MB are adsorbed by BMO@BOC, MOF-199 and BMO@BOC@MOF-199, respectively. The higher adsorption capacity of BMO@BOC@MOF-199 could be due to its higher surface area and larger pore volume . For single MO solution, nevertheless, only 16%, 13% and 7% of MO are adsorbed by BMO@BOC, MOF-199 and BMO@BOC@MOF-199, respectively. The different adsorption efficiency for MB and MO could be relative to their different molecular structures, which have different electrostatic interactions with adsorbent surface. For single RhB and single Cr(VI) solution, BMO@BOC@MOF-199 has adsorbed 30% RhB and 10% Cr(VI). In RhB-MO mixture solution, 32% RhB and 9% MO can be adsorbed by BMO@BOC@MOF-199, while in Cr(VI)–RhB-MO mixture solution, 7% Cr(VI), 3% RhB and 42% MO can be adsorbed by BMO@BOC@MOF-199. It is seen that in RhB-MO mixture solution, the adsorption efficiencies of RhB and MO by BMO@BOC@MOF-199 do not obviously change as compared to single RhB and single MO solution, while in Cr(VI)–RhB-MO mixture solution, the adsorption efficiency of MO has increased by 5 times, compared to single MO solution; but the adsorption efficiency of RhB has decreased by 9.7 times as compared to single RhB solution, and the adsorption efficiency of Cr(VI) has decreased slightly, compared to single Cr(VI) solution. The results are mainly attributed to the competitive adsorption on the adsorbent surface. This work can help us to understand the adsorption process for practical wastewater.

Zn 3 In 2 S 6 /Bi 2 MoO 6 (ZIS/BMO) type-II heterojunction composite is designed as a cooperative photoredox catalyst for integrating H 2 production and furfural (FAL) synthesis. • The type-II band alignment in ZIS/BMO can not only promote the separation and migration of charge carriers but also obtain the effective separation of oxidation and reduction reaction sites, thereby enhancing the photocatalytic activity. • This work is expected to provide new insights into achieving synergistic clean energy production and biomass-derived molecules valorization. Solar-driven H 2 production integrated with biomass valorization represents an appealing avenue to simultaneously generate clean energy and realize atom-economical chemical synthesis. Herein, we fabricate Zn 3 In 2 S 6 /Bi 2 MoO 6 (ZIS/BMO) type-II heterojunction composites as photocatalysts for a cooperative catalysis integrating H 2 production with the conversion of furfuryl alcohol (FOL) into furfural (FAL) under visible-light illumination. The type-II band alignment in the ZIS/BMO heterojunction enables not only the effective separation of oxidation and reduction reaction sites but also efficient charge separation and interfacial migration, thereby enhancing the photocatalytic performance. Specifically, the FAL formation and H 2 evolution rates over ZIS/BMO are 7.2 and 6.7 times higher than those over ZIS, and 9.6 and 12.4 times higher than those of BMO, respectively. Mechanistic insight studies reveal that carbon-centered radicals (•CH(OH)C 4 H 3 O) are key intermediates in the photocatalytic conversion of FOL to FAL. This work would provide a new perspective into the design of type-II heterojunction semiconductor-based photocatalysts for synergistic clean energy production and biomass valorization.

Photovoltaic devices based on single-film architectures, often realized in ferroelectric thin films, are valued for their structural simplicity and low fabrication costs. Nonetheless, their practical use is constrained by wide bandgaps and limited photoelectric responsivity. This study demonstrates a robust photovoltaic effect in paraelectric Bi 2 MoO 6 thin films fabricated through the sol-gel technique. By introducing an excess of bismuth into the precursor solution, the Bi content within the films is effectively tuned, revealing a strong dependence of the photovoltaic behavior on Bi concentration. The internal electric field driving the photovoltaic response is attributed to a compositional gradient of Bi ions across the film. Under 365 nm illumination, the optimized Bi 2 MoO 6 film exhibits notable photovoltaic performance, including a photoelectric responsivity of 31.25 mA/W, a short-circuit current density of 0.25 mA/cm 2 , and an open-circuit voltage of 0.36 V. This study not only expands the application of Bi 2 MoO 6 in photovoltaic field but also proposes an approach to design the photovoltaic effect in paraelectric oxides.

The development of versatile photocatalysts is crucial for comprehensive solutions to the intertwined challenges of the energy crisis and environmental pollution. This study presents a novel Bi3TiNbO9/Bi2MoO6(BTNO/BMO) heterojunction fabricated via a solvothermal method. Advanced characterization techniques verified the successful synthesis of the as-integrated BTNO/BMO heterostructure. The BTNO/BMO composite exhibited superior performance in multiple applications: efficient degradation of tetracycline reaching 90.2%, removal of gaseous nitric oxide (NO), and photocatalytic reduction of carbon dioxide (CO2) to carbon monoxide (CO) with a yield of 51.3 μmol·g−1. The constructed Type-II heterojunction demonstrated a remarkable ability to suppress charge recombination, thereby significantly enhancing the photocatalytic activity. This work highlights the dual-functional capability of the BTNO/BMO heterojunction for simultaneous environmental purification and fuel production, providing a promising material platform and a strategic design concept for sustainable technological development.

The electron mediator plays an important role in charge transfer in an artificial all-solid-state Z-scheme system. According to the energy band theory, a visible light photocatalytic system was designed by using reduced graphene oxide (RGO) as the electron mediator. The as-prepared g -C 3 N 4 /RGO/Bi 2 MoO 6 composite was synthesized by hydrothermal process, and it was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), nitrogen sorption , Raman spectroscopy , Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectrometer (XPS) and diffuse reflectance spectroscopy (DRS). The photocatalytic activity of the g -C 3 N 4 /RGO/Bi 2 MoO 6 composite was evaluated by analyzing the degradation of Rhodamine B (Rh B) under visible light irradiation. The photocatalytic degradation rate of Rh B for the g -C 3 N 4 /RGO/Bi 2 MoO 6 composite was 8.73 and 5.19 times for the Bi 2 MoO 6 and g -C 3 N 4 /Bi 2 MoO 6 composite, respectively. The matched Fermi level structure provided the favorable interfacial charge transfer from the Bi 2 MoO 6 Photosystem II (PS II) to the g -C 3 N 4 Photosystem I (PS I) to promote the photocatalytic degradation of Rh B, suggesting that RGO was a suitable electron mediator in the Z-scheme system. The present study can provide a scientific basis for the rational design and realization of the Z-scheme system in environmental application.

In this study, Bi 2 MoO 6 /FeVO 4 core–shell heterojunction was adopted as sonophotocatalyst to investigate its sonophotocatalytic degradation of ciprofloxacin (CIP) under ultrasonic and visible light. The properties of Bi 2 MoO 6 /FeVO 4 sonophotocatalyst were analyzed by XRD, FTIR, SEM, TEM, BET, DRS, XPS, PL and EIS. The effects of different operating parameters on the sonophotocatalytic degradation performance of CIP were investigated. Under the optimal operating conditions, a CIP degradation efficiency of 98.2 % and a mineralization rate of 68.9 % could be achieved after 60 min of reaction. Kinetic studies showed that the degradation process obeyed a pseudo-first-order reaction with a rate constant of k sonophotocatalytic > k photocatalytic > k sonocatalytic . Before and after the addition of H 2 O 2 , the sonophotocatalytic degradation of CIP reached high synergy values of 2.02 and 2.50, respectively. The synergistic effect of degradation can be attributed to the generation of OH, O 2 − and h + in the system. Contribution rate calculation displayed that OH and h + were the most significant reactive oxygen species. In addition, twenty degradation products were identified by HPLC-MS analysis, and the toxicity of the degradation products was further analyzed by ECOSAR. Ultimately, three potential degradation pathways for CIP were proposed.

As a widely used antibiotic, tetracycline (TC) is a prevalent aquatic contaminant. Its environmental persistence presents substantial ecological hazards and potential health risks. This research utilized an in situ hydrothermal technique to modify Bi 2 MoO 6 (BMO) with N-doped biochar (NBC), yielding a highly efficient photocatalyst. The photocatalytic efficacy of the manufactured materials in degrading TC under visible light was evaluated by characterizing its morphology and optical properties. Experimental findings demonstrated that the ideal mass ratio of NBC in the NBC/BMO composites was 20 wt%. In 50 mL of 40 mg L −1 TC solution, 0.2 g of catalyst achieved an adsorption-photocatalytic efficiency of 86.1% after 60 min of dark adsorption followed by 120 min of photocatalytic treatment, which was 2.26 and 1.39 times greater than BMO and 20% BC/BMO, respectively. The adsorption kinetics conformed to a pseudo-second-order model, with a maximum adsorption capacity of 19.45 mg g −1 , signifying that chemical adsorption was the predominant process. The enhanced adsorption performance was attributed to N-doped effectively promoting the separation and migration of photogenerated electron–hole pairs, significantly reducing carrier recombination rates. Concurrently, the composites exhibited a pronounced visible light absorption red shift, regulating optical bandgap and markedly improving visible light utilization. Superoxide radicals (•O 2 − ) and holes (h + ) were key active species in the photocatalytic degradation of TC. After five regeneration cycles, the composites maintained high removal efficiency for TC. This research not only provides a simple preparation method for N-doped BC photocatalysts but also offers an effective and low-cost strategy for utilizing biomass resources to remediate antibiotic-contaminated water bodies.

In this work, Bi 2 MoO 6 /BiFeWO 6 heterojunction was synthesized for the first time by solvothermal and calcination methods. The heterostructured Bi 2 MoO 6 /BiFeWO 6 exhibited higher photocatalytic oxidation/reduction efficiency than Bi 2 MoO 6 for the removal of rhodamine b (RhB) dye under visible light, which was attributed to the combined effect of the n-n heterostructure and oxygen vacancies (OVs). The OVs generated by calcination can accelerate the separation of photogenerated electrons and holes. Moreover, it is also able to trap electrons to reduce the recombination of electrons and holes. In cyclic experiments, the removal efficiency was maintained above 95% after 4 times of the same operation. The effective photocatalytic mechanism of n-n heterojunctions was demonstrated by trapping experiments and EPR . The research of Bi 2 MoO 6 /BiFeWO 6 is beneficial to expand the advantages of bismuth-based semiconductors for environmental remediation.

A W 18 O 49 /Bi 2 MoO 6 heterojunction photocatalyst with favorable photothermocatalytic activity was constructed in this study. Its physicochemical properties were characterized and analyzed, and its photothermocatalytic performance was evaluated through catalytic activity tests conducted under full solar spectrum conditions. The results show that W 18 O 49 /Bi 2 MoO 6 exhibits superior photothermal catalytic activity compared to single Bi 2 MoO 6 and W 18 O 49 . Among them, the W 18 O 49 /Bi 2 MoO 6 heterojunction with a mass ratio of 7 % has the highest CO yield, reaching 140.03 µmol/g, which is 7.5 times higher than that of pure W 18 O 49 . The interaction between W 18 O 49 and Bi 2 MoO 6 endows W 18 O 49 /Bi 2 MoO 6 with good photogenerated carrier separation and migration efficiency, as well as photothermal catalytic activity. This provides ideas for designing photocatalysts with efficient photothermal catalytic CO 2 reduction.

Herein, a series of ultrathin h-BN/Bi 2 MoO 6 heterojunction with excellent photocatalytic activity has been firstly prepared via a feasible solvothermal method . Our results suggest that the optimized photocatalyst possesses a high degradation ratio of tetracycline (TC), oxytetracycline (OTC) and doxycycline (DC) up to 99.19%, 95.28% and 91.04% under visible-light irradiation, respectively. We highlight that the outstanding photocatalytic activity is mainly attributed to the prominent performance of tetracycline adsorption on h-BN and the dominant visible-light absorption by Bi 2 MoO 6 as well as the effective photogenerated carrier separation induced by the synergetic effect between h-BN and Bi 2 MoO 6 . Moreover, DFT calculations reveal that the built-in electric field formed between h-BN and Bi 2 MoO 6 gives rise to the separation of carriers and the polarization of tetracycline molecules. Last but not the least, the specific process and micro-mechanism of the photocatalytic tetracycline degradation under visible-light driven have also been illuminated. The present work pioneers the application of ultrathin h-BN/Bi 2 MoO 6 heterojunction as a novel tetracycline degradation photocatalyst and further guides the design of more visible-light photocatalysts.

The application of photocatalytic Hg 0 oxidation under visible light is an up-and-coming method to solve the problem of energy shortage and environmental pollution. In this work, iodine doped Bi 2 MoO 6 nanomaterials were prepared by one-step solvothermal method . The photocatalytic oxidation efficiency was greatly improved by iodine doping from 35.5% to 95.2% in the N 2 + 4% O 2 atmosphere under visible light. The main reason was that iodine doping decreased the band gap of the catalyst, expanded the optical response range and intensity, sped up the separation rate of photoinduced carriers and reduced the recombination rate. In addition, the flue gas components of SO 2 and NO played a promoting role in mercury removal. Iodine doped Bi 2 MoO 6 had good stability and still maintained high mercury removal efficiency after 5 cycles. Density functional theory (DFT) calculations and experiments demonstrated that iodine doping changed the valence band and conduction band of the catalyst, making superoxide ions, hydroxyl radicals and photoinduced hole become the active species of the catalytic reaction .
