Designing and modification of bismuth oxyhalides BiOX (X = Cl, Br and I) photocatalysts for improved photocatalytic performance

Irshad Ahmad et al.

Summary: Photocatalysis is a promising technology for solving global environmental and energy challenges, with a focus on the design and modification of BiOX materials to improve their photocatalytic response and efficiency. Despite the unique properties of BiOX materials, such as their layered structure and tunable optical properties, limitations like rapid charge carrier recombination and limited light absorption hinder their industrial applications and efficiency.

Enhanced photocatalytic performance of TiO2/BiOI heterojunctions benefited from effective separation of photogenerated carriers

Yanbai Chen et al.

Summary: The TiO2/BiOI heterojunctions prepared by facile hydrothermal synthesis exhibit enhanced photocatalytic activity, with significantly improved separation efficiency of photogenerated carriers and introduction of more oxygen vacancies. The photocatalytic activity of the TiO2/BiOI heterojunctions is almost 4 times higher than that of neat BiOI under simulated sunlight, suggesting a step-scheme mechanism for the separation of photoactivated carriers.

Recent developments on bismuth oxyhalides (BiOX; X = Cl, Br, I) based ternary nanocomposite photocatalysts for environmental applications

Malathi Arumugam et al.

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.

Summary: Bismuth oxyhalides (BiOX, X = Cl, Br, I) with two-dimensional/two-dimensional (2D/2D) heterostructures have been successfully prepared without using any solvent recently. The BiOX/RGO heterostructures exhibit oxygen-rich vacancies and a short fabrication time of 15 min, promoting carrier separation efficiency and visible-light absorption. The photocatalytic performance of BiOX/RGO composites in degrading organic pollutants was significantly enhanced, showing improved degradation rates compared to pure BiOX.

Tao Li et al.

Summary: The degradation of pyrimethanil (PYR) was efficiently achieved through the activation of oxone by the S-TiO2 (ST) photocatalyst with an optimal molar ratio of S/Ti at 0.25. Various reaction parameters and reactive species generated in the process influenced the degradation efficiency, while the reusability test demonstrated the stability of the ST photocatalyst. Overall, the ST/Oxone/Vis LED process showed potential for removing organic pollutants with the generation of different degradation intermediates through multiple pathways.

Effect of reaction mediums on photocatalytic performance of BiOX (X = Cl, Br, I)

Huimei Yu et al.

Summary: This study investigates how solvents affect the energy band structure and microstructure of BiOX photocatalysts, with ethylene glycol showing the best photocatalytic activity and aqueous solution demonstrating the worst performance. The results show that solvent-induced microstructure changes play a significant role in determining the photocatalytic performance of BiOX, while the impact on band potentials is relatively inconsistent. Additionally, different BiOX materials exhibit varying photocatalytic activity for different pollutants under different solvents.
