The unique properties of BiVO4 arise from its band gap and crystal structure. It has a narrow band gap of around 2.4 eV, which allows it to absorb visible light efficiently. Furthermore, BiVO4 exists in multiple crystalline phases, such as monoclinic and tetragonal, which influence its photocatalytic activity. The monoclinic phase is especially noted for its superior catalytic performance due to better charge separation capabilities.
