• CO2 photocatalytic reduction mainly to CH4 is reported.
• GaP/TiO2 composites exhibit photocatalytic activity under simulated solar light.
• The maximum activity was observed with the 1:10 GaP:TiO2 weight ratio.
• Photo-activity can be attributed to an efficient charge transfer between GaP and TiO2.
GaP/TiO2 composites exhibited a remarkable photocatalytic activity for CO2 reduction in the presence of water vapor producing methane. By decreasing the GaP:TiO2 mass ratio an increase in the photocatalytic activity of the composite was observed for up to a 1:10 mass ratio. The photocatalytic activity of the composite can be attributed to the band structures of the solids as well as to the efficient charge transfer between GaP and TiO2 heterojunction.
