Summary: In this study, BiVO4-based solid solutions, Bi0.5Y0.5VO4, were prepared using the MOF-derived method. Characterization of the samples revealed that Y sources facilitated the generation of tetragonal phase BiVO4, which played a crucial role in enhancing the photocatalytic overall water splitting property. Additionally, the deposition of metallic Pt particles as co-catalysts resulted in a decrease in the ratio of H-2:O-2, suggesting the emergence of an electric field shield effect to regulate the interfacial internal electric field further.
