Summary: Photocatalytic technology utilizing sunlight as a driving force can convert solar energy into other energy sources for storage and use. CdS, as a typical reducing semiconductor, has attracted attention in photocatalysis due to its suitable bandgap and strong reducing ability. However, the photocatalytic performance of CdS is limited by carrier recombination and photocorrosion. Therefore, CdS has been widely developed as a reducing photocatalyst in constructing S-scheme heterojunctions to overcome these limitations.

Summary: ZnO nanosheets, 2D/1D ZnO/CdS hybrid, and ternary ZnO/CdS/GO S-scheme heterojunction photocatalyst were fabricated using a low-temperature hydrothermal technique. The addition of CdS and GO significantly improved the photocatalytic activity of ZnO, as demonstrated by the higher dye degradation rate constant and the increased visible light absorption. CdS also regulated the size and distribution of ZnO nanosheets, increasing the specific surface area of the sample. The presence of CdS and GO promoted the rapid separation of photoexcited carriers in ZnO, and GO further enhanced the transmission rate of electrons and the photoelectric stability of the ZnO/CdS heterogeneous photocatalyst.

Summary: Photocatalytic H2O2 evolution from H2O and O2 has gained increasing attention. This study successfully synthesized an efficient Bi/BiOBr-CdS S-scheme heterojunction via solvothermal method, which exhibits a high H2O2 production activity of 346.4 μmol/L/h through H2O oxidation and O2 reduction reactions. The synergistic effect of S-scheme heterojunction and metal Bi reduces the band gap, facilitates charge carrier separation, and induces high formation rate constants of H2O2. These findings provide new strategies and ideas for maximizing the redox ability of S-scheme heterojunctions.

Summary: In this study, a two-dimensional CdS/SnS2 heterostructure is proposed as a possible water splitting photocatalyst. The heterostructure enhances light absorption and spatially separates the photoinduced carriers, resulting in extended carrier lifetimes. The introduction of a S-vacancy into SnS2 effectively lowers the overpotential of the oxygen evolution reaction, enabling spontaneous water splitting under light irradiation.

Summary: The hybridization of different photocatalysts, such as BP and g-C3N4, has been shown to enhance the photocatalytic efficiency for CO2 reduction. Theoretical calculations indicate that electrons transfer from g-C3N4 to BP due to the built-in electric field at the interface, leading to efficient separation of photogenerated charge carriers. The S-scheme heterojunction between BP and g-C3N4 allows for the optimized reduction of CO2, making the BP/g-C3N4 composite a promising CO2 reduction photocatalyst.

Summary: Photocatalytic technologies have been widely applied in hydrogen production, environmental purification, CO2 reduction, catalytic organic synthesis, and other fields due to their environmental friendliness and convenient operation. ZnIn2S4 photocatalyst, a ternary metal sulfide, has attracted attention for its simple synthesis, excellent stability, and appropriate band structure. However, its low solar energy utilization and rapid recombination of photogenerated charges hinder its photocatalytic efficiency. By constructing heterojunctions with other semiconductors, the above shortcomings can be overcome. This review presents a systematic description of ZnIn2S4-based S-scheme heterojunction photocatalysts, including their research background, scientific mechanism, design principles, preparation strategies, and characterization methods. The extensive applications in hydrogen production, CO2 reduction, environmental purification, and other fields are also discussed. Several drawbacks and prospects for the future development of ZnIn2S4-based S-scheme heterojunctions are proposed.

Summary: This study demonstrates that amorphization is an effective strategy to address critical issues in aqueous aluminum metal batteries (AMBs). By shifting the reduction potential for aluminum deposition, the amorphous aluminum (a-Al) interfacial layer facilitates stable aluminum plating and stripping, while mitigating passivation and enhancing interfacial ion transfer kinetics. The use of a noncorrosive, low-cost, and fluorine-free electrolyte further contributes to the excellent electrochemical performance of the AMBs.

Summary: Electrocatalytic nitrogen reduction reaction (ENRR) is a potential alternative to the Haber-Bosch approach, and a simple and effective strategy of iron surface implantation is recommended to enhance the NRR activity. The Fe/Cu catalyst achieved a NH3 yield rate of 6.8 +/- 0.4 mg/h/cm and a Faradaic efficiency of 16.0 +/- 1.1% in an alkaline electrolyte. Theoretical calculations showed that iron implantation can improve nitrogen adsorption, weaken the N-N bond, and lower the energy barrier of the potential determining step for promoting the NRR process.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
