Developing integrated photocatalysts with multifunction in energy conversion and environmental improvement is an effective strategy for promoting solar-to-chemical application under the dual challenges of energy crisis and environmental pollution. Herein, this work uses hexagonal CoAl-LDH nanosheets as carriers and constructs a type II heterojunction of CoAl-LDH/CdS by in-situ growth of CdS nanoparticles. By utilizing the broad absorption and excellent carrier properties of CoAl-LDH nanosheets in the visible light region, combined with the high optical quantum yield of CdS, and through the construction of heterostructures, a multifunctional CoAl-LDH/CdS composite photocatalytic material is obtained. Moreover, by optimizing the loading amount of CdS, the photodegradation rate of the photocatalyst with a mass ratio of CoAl-LDH/CdS-2 is the highest (degradation rate = 88.48% at t = 60 minutes), which is 1.18 times and 8.62 times higher than that of CdS and CoAl-LDH monomers, respectively. Meanwhile, the highest CO production of CoAl-LDH/CdS-1 is 39.02 mol/g (t = 5 h), which is 4.2 and 2.5 times of bare CoAl-LDH and bare CdS, respectively. These results are mainly attributed to the construction of a tight heterojunction between CoAl-LDH nanosheets and CdS nanoparticles in composite, and the rich coupling interface greatly reduces the recombination rate of photogenerated carriers. This provides a theoretical basis for the development of multifunctional photocatalysts. [ABSTRACT FROM AUTHOR]

SiO2 @ g-C3 N4 Core-shell nanospheres and Ag/AgCl/SiO2 @ g-C3 N4 composites were synthesized by hard template method, their structure and optical properties were characterized. The performance and mechanism of visible light photocatalytic degradation of ofloxacin (OFX) were investigated. The results showed g-C3 N4 is coated on the surface of SiO2 nanospheres, most of them are spheres with a diameter of 400 nm. The addition of Ag/AgCl constructs a heterojunction and significantly improves the separation efficiency of photogenerated carriers. Compared with pure g-C3 N4, the photocatalytic degradation of ofloxacin by Ag/AgCl/SiO2@ g-C3 N4 composites was significantly improved. When the initial concentration of OFX is 10 mg/L, the catalyst dosage is 0.2 g/L, and the degradation rate of OFX can reach 72.59% after 40 min of visible light irradiation at 100 mW/cm². Free radical quenching experiments showed that the main active substance in the photocatalytic degradation of pollutants by Ag/AgCl/SiO2@ g-C3 N4 composite was photogenerated holes.

In recent years, the management of antibiotics has garnered significant attention due to their unique ecological effects, such as inducing antibiotic resistance. Traditional water treatment methods struggle to effectively eliminate trace amounts of antibiotics, posing threats to both ecological environment and drinking water safety. Photocatalysis technology, with its advantages of mild reaction conditions, low cost, high degradation efficiency, and thorough removal, holds great potential for the degradation of antibiotics. Carbon nitride (CN) materials, serving as non-metallic photocatalysts responsive to visible light, have been a focal point in photocatalysis research. However, pure CN suffers from issues like insufficient sunlight absorption, small surface area, and rapid recombination of photogenerated electron-hole pairs, resulting in low photocatalytic activity. Modification strategies such as element doping and the formation of heterojunctions with other materials can effectively enhance the photocatalytic performance of CN, improving its light absorption, promoting the separation and transfer of photogenerated charge carriers. Here, we reviewed the significant progress in the design strategies and mechanisms of charge carrier separation/transfer in CN-modified photocatalysts, summarized their application in the photocatalytic degradation of antibiotics, and prospected the directions for developing advanced CN-modified photocatalysts.

To improve the water dispersibility of graphene based powder photocatalyst, titanium dioxide / graphene (TG) was first prepared using a hydrothermal method in this paper, and then the ternary composite photocatalytic materials were prepared by covalently grafting TG with dyes containing hydrophilic groups. The bandgap, water dispersibility, and photocatalytic degradation performance of methylene blue (MB) simulated wastewater of the photo-catalysts were mainly investigated. The results showed that the bandgaps of the DTG series of composites were narrowed compared to that of TG, extending the light response range to the visible light region. The composite D2.70 TG exhibited good water dispersibility, and no significant precipitation aggregation occurred after 7 days of testing. The removal rate of MB in the simulated wastewater by D2.70 TG under the irradiation of visible light for 2 h was over 99%, and the removal rate remained above 95% after 5 cycles of experimentation.

Water samples were collected during freezing and flowing conditions from eight sites along the Baotou section of the Yellow River. The main aims of this study were to obtain information on the fluoranthene concentrations in freezing-thawing process; to determine how fluoranthene concentrations were distributed in water; to discuss the photodegradation of fluor anthene in the water phase; to investigate the influence of light-sensitive materials (H2O2, acetone and sediment) on the photo degradation of fluoranthene in the water phase. The results indicated that fluoranthene concentrations were relatively high at sites S2 and S5, and residue levels were lower at points S4, S6 and S7. The fluoranthene light experiment was carried out under exposure to UV light with low fluoranthene concentrations, using a light conversion function in the water and ice phase, after 72 h the concentration the degradation rate reached 90%. The degradation rates of fluoranthene in water phase were lower with acetone, sediment and low concentrations of H2O2 than without, and the fluoranthene degradation was consistent with a first-order kinetics reaction, likewise, high H2O2 concentrations promoted photoconversion.

Under UV irradiation conditions, bisphenol A (BPA) was used as a model compound to study the composite effects of representative soluble components humic acid ( HA), Fe 3 +, and Cl - on the photolysis of BPA in the aqueous environment using response surface methodology ( RSM) . Results show that HA and Fe 3 + are the significant factors affecting the photodegradation of BPA, followed by NO - 3 and Cl - . HA, NO - 3 and Cl - significantly inhibits the photolysis of BPA, while Fe 3 + promotes it (P < 0. 05) . When HA, Fe 3 +, NO - 3 and Cl - co-exists in the water environment, an interaction on the photolysis of BPA is established. As significant factors, the combination of Fe 3 + and Cl - or HA respectively inhibits the photodegradation of BPA, while the coexistence of HA-Cl - or HA-NO - 3 shows promoting effect. As non-significant factors, there are antagonistic effects between NO - 3 and Fe 3 + or between NO - 3 and Cl - . Radical scavenging experiments unveils that the most important factor HA on BPA photodegradation is mainly attributed to triplet-excited DOM. The predicted value of the model obtained from the natural water sample is in good agreement with the experimental value, indicating that the model can be used to estimate the photolysis of BPA in the natural water sample used, but it also has certain limitations.

In this paper, ZnO/ g-C3N4 series composite photocatalysts were prepared by thermal polymerization and hydrothermal method. The structure, morphology and light absorption properties of the prepared samples were characterized and tested. The photocatalytic performance of these samples was evaluated by the photocatalytic degradation of methylene blue (MB) and the photolysis aquatic hydrogen under visible light irradiation. The experimental results indicate that the performances of the ZnO/ g-C3N4 composite photocatalysts are superior to those of ZnO and g-C3N4 . Moreover, when the molar ratio of ZnO and g-C3N4 is 1:1, the photocatalytic performance of the prepared ZnO/ g-C3N4 composite samples is the best.

The photodegradation behavior of the mixture of chlorothalonil and profenofos in water was investigated under high pressure mercury lamp (HPML). The results showed that the half-life of chlorothalonil at 3 μmol/L was 122.46 min under the HPML irradiation, and the half-lives of chlorothalonil were 64.54, 38.25 and 33.05 min in the presence of 1, 2 and 3 equivalent of profenofos. The half-lives of 3, 6, and 9 μmol/L profenofos were 87.85, 86.11 and 87.63 min, while they were 85.57, 83.51 and 84.32 min in the presence of chlorothalonil, respectively. This indicates that profenofos promoted the photodegradation of chlorothalonil in water and the promotion effect was increased as the concentration of profenofos increased. Chlorothalonil did not affect the photodegradation of profenofos. The main photodegradation product of chlorothalonil was 4-hydroxyl chlorothalonil with and without profennofos. Five photodegradation products of profenofos were detected, namely, 4-bromo-2-chlorophenyl hydrogen phosphate ethyl ester, O-(4-bromo-2- chlorophenyl)-O-ethyl-S-hydrogen phosphate, O-(2-chlorophenyl)-O-ethyl-S-propyl phosphorothioate, (2-chloro-4-hydroxyphenyl)-O-ethyl-S-propyl phosphorothioate, and 2-chloro-4-bromophenol. Profenofos promoted the degradation of chlotothalonil via the generation of more hydroxyl radicals. This study provides important theoretical support for the evaluation of the environmental ecotoxicity of combined pollution of chlorothalonil and profenofos [ABSTRACT FROM AUTHOR]

The photocatalytic degradation of gaseous benzene was investigated. The results show that the core and shell of microspheres gradually separates with the increase of solvothermal temperature, and the hollow structure become more obvious, and displays a secondary structure composed of nanoparticles below 20 nm. The specific surface area of the microspheres is up to 265. 4 m2 / g, the porosity is up to 0. 247 8 cm3 / g, the light absorption performance is higher than P25 TiO2, and the edge of the light absorption band shows "blue shift". The core-shell structure microspheres exhibit adsorption synergistic photocatalytic degradation of benzene, especially the sample prepared at 180 ℃ has the highest photocatalytic activity, the excellent performance may ascribe to the sufficient scattering and absorption of light by the core-shell structure, its excellent crystallinity and high specific surface area.

The photocatalytic degradation rate of MB over 0.2MoUiO was 1.89 times higher than those single system of MB. Meanwhile, the reduction rate of Cr(VI) over 0.2MoUiO reached 2.87 times compared with it. The enhanced performance is attributed to that Z-scheme heterojunction formed between UiO-66 and MoS2, which enhanced light absorption capacity by 0.2MoUiO and accelerates the separation of electrons and holes, It was verified by PL, XPS valence band test and UV-vis DRS. • OH and • O2- was the main active substance of the photocatalyst of MB by mechanism and ESR test analysis, and the process of synergistic degradation of Cr(VI), MB could act as a sacrificial agent to effectively consume h+ and • O2-, then promote electron accumulation, which was conducive to reducing Cr(VI).

Copper based sulfide photocatalysts have attracted extensive attention of researchers due to their narrow band gap, local surface plasmon resonance effect, good absorption ability to visible light, rich in reserves and non-toxic properties. However, the high recombination rate of photogenerated electrons and holes, and the low utilization efficiency of visible light hinder their application in the field of photocatalysis. Therefore, researchers have tried different modification strategies to improve their photocatalytic performance. This paper focuses on the modification strategies of copper based sulfides, mainly discusses the modification of the photocatalytic performance of copper based sulfides by morphology regulation, crystal phase regulation, and semiconductor heterojunction, etc., and analyzes the effect of different modification methods on the improvement of the photocatalytic performance. The application of copper based sulfides in the photocatalytic degradation of organic pollutants, photocatalytic splitting water for hydrogen production, photocatalytic reduction of CO2, etc. are discussed, and the development direction of copper based sulfide modification is prospected.
