Enhanced Photocatalytic Efficiency Through Oxygen Vacancy‐Driven Molecular Epitaxial Growth of Metal–Organic Frameworks on BiVO 4

Abstract Efficient charge separation at the semiconductor/cocatalyst interface is crucial for high‐performance photoelectrodes, as it directly influences the availability of surface charges for solar water oxidation. However, establishing strong molecular‐level connections between these interfaces to achieve superior interfacial quality presents significant challenges. This study introduces an innovative electrochemical etching method that generates a high concentration of oxygen vacancy sites on BiVO 4 surfaces (Ov‐BiVO 4 ), enabling interactions with the oxygen‐rich ligands of MIL‐101. This reduces the formation energy and promotes conformal growth on BiVO 4 . The Ov‐BiVO 4 /MIL‐101 composite exhibits an…
