The review article delves into the growing interest in solar-driven hydrogen peroxide (H2O2) production as a safe, cost-effective, and environmentally friendly process. Utilizing renewable resources like water, oxygen, and solar energy, H2O2 synthesis minimizes waste production. Bismuth vanadate (BiVO4) has emerged as a prominent oxide semiconductor for the selective production of H2O2 under visible light, achieved through direct oxygen reduction and water oxidation pathways. Over the past decade, significant progress has been made in utilizing BiVO4-based materials for solar H2O2 production, focusing on powder suspension (PS) and photoelectrochemical (PEC) systems. The article discusses fundamental principles, methodologies for performance assessment, development of photocatalysts and photoelectrodes, and optimization of reaction conditions. Various strategies like heterojunction, doping, crystal facet engineering, cocatalyst loading, and surface passivation have been effective in enhancing H2O2 generation. The review provides insights into implementing these strategies in both PS and PEC systems, highlighting their similarities and differences. Furthermore, it addresses the challenges and future directions in the field to facilitate the rational design of high-performing BiVO4-based photocatalysts and photoelectrodes for H2O2 production under visible light.
