Solar‐Driven Selective Oxidation Over Bismuth‐Based Semiconductors: From Prolific Catalysts to Diverse Reactions

Advanced Functional Materials, Год журнала: 2024, Номер 34(27)

Опубликована: Март 4, 2024

Abstract Synthesis of organic compounds often necessitates rigorous reaction conditions or the involvement hazardous oxidants, resulting in substantial energy consumption and considerable environmental damage. Photocatalytic selective oxidation represents a green environmentally friendly way to obtain high‐value chemicals, which has developed rapidly recent years. Bismuth‐based (Bi‐based) semiconductor materials have gained intense interest synthesis due their diverse crystal structures compositions, tunable band structure, outstanding photocatalytic performance. Herein, systematic summary solar‐driven over varieties Bi‐based semiconductors is provided. Initially, reactive species involved oxidation, widely used methods for synthesizing these are meticulously classified. Concerning reactions, variety modification strategies, with focus on separation photogenerated carriers regulation extensively documented. Highlights applications mechanism discussions photocatalysts including alcohol C─H bond activation, amine sulfide as well coupling reactions photoreduction. Finally, future development prospects challenges field proposed, hoping provide valuable insights guidance design oxidation.

Boosting the sonophotocatalytic performance of BiOCl by Eu doping: DFT and an experimental study

Ultrasonics Sonochemistry, Год журнала: 2023, Номер 99, С. 106543 - 106543

Bismuth oxychloride (BiOCl) has a unique layered structure and uneven charge distribution, resulting in an internal electric field under polarization, which promotes the efficient separation migration of photogenerated carriers. BiOCl could be candidate for sonophotocatalysts. However, low utilization visible light limits application photocatalysts. In this study, photocatalytic performance rare earth element (Nd, Sm, Eu, Er Er)-doped was studied by density functional theory (DFT) experimentally to screen high-performance catalysts. The band structure, states, optical properties were calculated DFT method predict activity earth-doped BiOCl. built-in formed Eu-doped inhibiting electron hole recombination can observed. Subsequently, photocatalyst sonophotocatalysts evaluated. results show that sonophotocatalytic is improved, consistent with theoretical prediction. Combining calculations experiments, enhanced, mainly due synergistic effect carrier recombination, expansion absorption region.
