Synergistic hydrazine-driven regulation and Mo/S co-doping to endow BiOBr with heterovalent molybdenum states and abundant oxygen vacancy defects for photocatalytic hydrogen evolution

A novel Mo/S co-doped BiOBr-based bimetal bismuth sulfur-oxybromide catalyst with heterovalent molybdenum states and abundant oxygen vacancy defects exhibits an excellent photocatalytic hydrogen evolution activity of 710.5 μmol h −1 .
