摘要： The mesoporous photocatalyst InVO4 was synthesized by the template-directing self-assembling method. The synthesized InVO4 was characterized by means of X-ray diffraction, transmission electron microscopy, N2 adsorption, and ultraviolet-visible spectroscopy. The results showed that the crystal structure of InVO4 could be controlled by changing the calcination temperature. Compared with the anatase TiO2 and conventional InVO4, the mesoporous InVO4 was more responsive toward visible light. The evolution rate of H2 from water over the mesoporous InVO4 achieved 1836 μmol/(g·h) under UV light irradiation, which was much higher than the anatase TiO2 and conventional InVO4.
