Sunlight-driven photocatalysis, which can produce clean fuels and mitigate pollutant degradation, has received extensive research attention due to its potential for addressing both energy shortages environmental crises. Bismuth (Bi)-based photocatalysts with broad spectrum solar-light absorption tunable structures, exhibit promising applications in solar-driven photocatalysis. Oxygen vacancy (OV) engineering is a widely recognized strategy that shows great accelerating charge separation small molecule activation. Based on OV engineering, this review focuses Bi-based provides comprehensive overview including synthetic methods, regulation strategies, photocatalytic field. The methods of OVs (BPOVs) are classified into hydrothermal, solvothermal, UV light reduction, calcination, chemical etching, mechanical based different reaction types, provide the possibility structural BPOVs, dimensional regulation, creation, elemental doping, heterojunction fabrication. Furthermore, also highlights CO2 N2 fixation, H2 generation, O2 evolution, cancer therapy, bacteria inactivation. Finally, conclusion prospects toward future development BPOVs presented.

Abstract Developing conductor‐mediated S‐scheme heterojunction photocatalysts imitating natural photosynthetic systems emerges as a promising approach to hydrogen peroxide (H 2 O ) production. However, achieving precise coupling between two semiconductors with charge shuttle and modulating the interfacial interactions still remain significant bottleneck. Herein, we propose catalyst architecture Cd single atom mediated formed by interfacing CdS TiO nanoparticles. This exhibits an H production rate high 60.33 µmol g −1 min under UV–vis light irradiation, which is attributed efficient transport at interface of thanks S‐scheme. In‐situ X‐ray photoelectron spectroscopy (XPS) electron spin resonance (ESR) spin‐trapping tests confirm transfer route. Femtosecond transient absorption (fs‐TA) other ex‐situ characterizations further corroborate across interface. work offers new perspective on constructing atoms heterojunctions enhance photocatalytic performance.
