Abstract

CeVO-based photocatalysts have been actively studied, but to the best of our knowledge, P-doped CeVO with enhanced photocatalytic activity has not been reported. Herein, novel P-doped CeVO nanorods were synthesized via a facile hydrothermal method. The doped P exists as PO tetrahedron which replaces VO tetrahedron. The crystal size, specific surface area, and light absorption ability of CeVO were tuned after doping CeVO by P. In particular, the separation and transmission efficiency of photogenerated electron-hole pairs were improved due to the internal electric field caused by the large charge density around PO tetrahedron. This conclusion was also confirmed by DFT calculations. The photocatalytic activities of different samples were tested via photodegradation of aqueous organic pollutants, and a feasible mechanism of photocatalytic reaction was proposed.
