Summary: Recently, the bismuth-rich strategy has been used to improve the photocatalytic performance of bismuth oxyhalides by increasing the bismuth content. However, the mechanism behind this strategy is not well understood. In this study, theoretical calculations and experiments were conducted to reveal the mechanism behind the bismuth-rich strategy in bismuth oxyhalide photocatalysts, providing important theoretical support for the future development of advanced photocatalysts.

Summary: Bismuth oxyhalides (BiOX, X = Cl, Br, and I) have attracted a lot of attention due to their unique layered structures, optical, and electronic properties. These bismuth-based photocatalysts have shown excellent efficiency in photocatalytic activities such as pollutant removal, water splitting, antibacterial activity, and sensor studies under visible light irradiation. However, their practical application is limited by their band structures and fast recombination of electron-hole pairs. Various modifications, such as doping and heterojunction design, have been explored to enhance their photocatalytic performance under visible light. This review summarizes the synthesis methods, modifications, and applications of bismuth oxyhalides in photocatalysis, hydrogen production, antibacterial studies, and sensing properties.

Summary: In this study, bismuth oxyhalides were synthesized and used as pre-catalysts for the electroreduction of CO2. The research found that residual I atoms in BiOI crystal lattice played a key role in enhancing the ECO2RR performance by interacting with CO2 via electron flow. This work highlights the importance of in-situ formation of halogen in ECO2RR and may lead to further research in this area.

Summary: A facile ultrasound-assisted alcoholysis method was used to anchor BiOCl0.5Br0.5 (BOCB) nanosheets onto natural schorl particulates, enhancing the visible-light-driven photocatalytic efficiency. The synergy between the external polarization electric field of schorl and the internal polarization electric field of BOCB effectively enhanced the separation of photogenerated electron-hole pairs, contributing to the improved photocatalytic performance. This study provides a new approach for developing polarization electric field-assisted strategies to enhance photocatalytic efficiency.

Summary: A novel magnetic Bi4O5Br2/SrFe12O19 nanocomposite was synthesized via a microemulsion method to improve the catalytic activity and recovery efficiency of photocatalysts. The photocatalyst showed enhanced degradation of Rhodamine B due to optimized energy band structure and the formation of an internal electric field in the type-II heterojunction. The primary active constituents in the photocatalytic reaction were identified as h(+) and O-center dot(2) through energy-band structure analysis and radical scavenging experiments.

Summary: In this study, a series of novel (BiO)(2)OHCl/BiOBr-x%B:DGNW (x = 0%, 1%, 1.5%, 2%) composites were successfully synthesized using a simple solvothermal synthesis method. The photocatalytic activity of these composites in the degradation of 5-fluorouracil (5-FU) under artificial solar radiation was assessed, and it was found that the introduction of boron-doped diamond/graphene nanowalls (B:DGNW) significantly enhanced the degradation rate of 5-FU. The results highlight the importance of B:DGNW in the separation of charge carriers and the improvement of photocatalytic activity.

Summary: In this study, a Fe3+-doped BiOCl(x)l(1-x) solid solution was synthesized on an amidoxime-functionalized fibrous support, resulting in high photocatalytic activity for the degradation of organic contaminants. The chelated interaction between the amidoxime groups and Fe3+ promotes the crystal growth of the new catalyst and tunes its electronic structure, improving light harvesting and oxygen vacancy creation efficiency. Additionally, the fibrous support acts as an electron sink for efficient charge separation.

Summary: The translation emphasizes on the development and application of bismuth oxyhalides (BiOX) for photocatalytic treatment of organic pollutants in wastewater. While BiOX shows good absorption of solar light, the rapid recombination rate of photogenerated charge carriers limits its practical application. To overcome this issue, the development of BiOX-based ternary nanocomposites has received significant attention.
