Description
Summary:As the continuation and advances in traditional BiOX (X = Cl, Br, I), bismuth-rich bismuth oxyhalides (Bi a O b X c ) show distinct differences in the surface local atomic structure, electronic structure, optical properties, and electrical conductivity relative to BiOX. These features endow bismuth-rich Bi a O b X c with more tunable properties to achieve excellent photocatalytic performance. Here, the state-of-the-art progress in bismuth-rich bismuth oxyhalides is reviewed to clarify the key structure-activity relationship for enhanced photocatalytic performance. Various methods for the controllable synthesis and formation mechanism of bismuth-rich Bi a O b X c are presented. Different strategies to tailor the photocatalytic behaviors are summarized, namely thickness tuning, morphological control, heteroatom doping, surface defect engineering, single atom engineering, surface modification, preparation of a solid solution and engineering of semiconductor heterojunctions. Moreover, the recent advances in Bi a O b X c for diversified photocatalytic applications, such as H 2 generation, O 2 production, CO 2 reduction, N 2 reduction, organic synthesis and pollutant removal, are summarized. Finally, the existing challenges and perspectives are also presented to bring about new opportunities for future research. The state-of-the-art progress in bismuth-rich bismuth oxyhalides is reviewed to clarify the key structure-activity relationship for enhanced photocatalytic performance.
