📄 Abstract

A monoclinic BiVO4 lattice was doped with phosphate to enhance photoelectrochemical and photocatalytic water oxidation activity under visible light by a factor of about 30 compared with pristine BiVO4. Electrochemical impedance spectroscopy measurements and density functional calculations revealed that much improved charge transfer characteristics of BiVO4 are mainly responsible for the greatly enhanced photoelectrochemical activity.
