Substitution of Ce(III,IV) ions for Bi in BiVO4 and its enhanced impact on visible light-driven photocatalytic activities

The recombination of photogenerated charges can be greatly depressed by the charged crystal defects in the Bi_1−xCe_xVO_4+δ novel solid solution photocatalyst and both ˙OH and ˙O₂⁻ could be detected in the photoreaction.
