Abstract
InVO4 and Ni–InVO4 were synthesized by a solid-state reaction route. The products were characterized by X-ray diffraction, UV–Vis diffusive reflectance spectroscopy and scanning electron microscope. Using glucose as an electron donor, photocatalytic hydrogen generation over InVO4 and Ni–InVO4 was investigated. The results showed that glucose was degraded effectively with the hydrogen generation. The photoactivity of InVO4 was enhanced when Ni was doped into the crystal structure. The effect of NaOH concentration on the hydrogen generation rate was also studied. The results exhibited that the basic condition is favorable for photocatalytic hydrogen generation, and there was an optimal NaOH concentration at 0.1 mol L−1.
