A comprehensive investigation of tetragonal Gd-doped BiVO4 with enhanced photocatalytic performance under sun-light

- Tetragonal Gd-BiVO4 with enhanced photocatalytic activity was synthesized.
- Gd doping can induce the phase transition from monoclinic to tetragonal BiVO4.
- GdVO4 seeds as crystal nucleus dominate the formation of tetragonal Gd-BiVO4.
- Tetragonal Gd-BiVO4 exhibits the excellent separation of electrons and holes.
- The contribution of high photocatalytic activity under sun-light is from UV-light.
