•The doping of NiOx can improve the photocatalytic activity of TiO2.•NiOx/TiO2 is active for photocatalytic H2 production from aqueous glycerol.•The catalytic performance of NiOx/TiO2 depends on calcination temperature.
The surface of a TiO2 material was modified by loading NiOx in 10 wt% by impregnation with nickel nitrate followed by calcination in air at different temperatures. The TiO2 and NiOx/TiO2 samples prepared were applied for photocatalytic H2 production from glycerol and water at 50 °C. The H2 evolution was enhanced by NiOx loading and was dependent on calcination temperature. A maximum H2 evolution was observed with 450 °C calcined NiOx/TiO2 sample. The properties of those TiO2 and NiOx/TiO2 samples were characterized by nitrogen adsorption, XRD, UV/vis, and XPS measurements to examine factors responsible for the enhancement of photocatalytic H2 evolution with NiOx loaded and calcined TiO2 samples.
