One-Pot in Situ Hydrothermal Growth of BiVO₄/Ag/rGO Hybrid Architectures for Solar Water Splitting and Environmental Remediation.

ABSTRACT: BiVO₄ is ubiquitously known for its potential use as photoanode for PEC-WS due to its well-suited band structure; nevertheless, it suffers from the major drawback of a slow electron hole separation and transportation. We have demonstrated the one-pot synthesis of BiVO₄/Ag/rGO hybrid photoanodes on a fluorine-doped tin oxide (FTO)-coated glass substrate using a facile and cost-effective hydrothermal method. The structural, morphological, and optical properties were extensively examined, confirming the formation of hybrid heterostructures. Ternary BiVO₄/Ag/rGO hybrid photoanode electrode showed enhanced PEC performance with photocurrent densities (J _ph ) of ~2.25 and 5 mA/cm² for the water and sulfate oxidation, respectively.
