| 英文摘要: | InVO4 was synthesized by solid-state reaction method using In2O3 and V3O4 as the starting materials. NiO was added as the cocatalyst. The catalysts were characterized by powder X-ray diffraction, scanning electron microscope, and ultraviolet-visible spectroscopy. The photocatalytic reduction of CO2 with water was carried out in a Pyrex reactor with KHCO3 aqueous solution bubbled with CO2 gas under visible light illumination. Many pinholes were observed on the InVO4 particles after loading with NiO cocatalyst. The band gap of NiO/InVO4 was lower than that of InVO4 due to the formation of subband in valence band by creating more defect sites on the surface of InVO4. Both NiO/InVO4 and InVO4 can reduce CO2 to methanol under visible light irradiation. The reaction rate increased with an increase of the loading of NiO cocatalysts. © 2015 Elsevier Ltd.
