Photocatalytic reduction of CO2 to hydrocarbons by using photodeposited Pt nanoparticles on carbon-doped titania

•Pt/C-TiO2 (0.5–3.0 wt.%) photocatalysts were synthesized by photodeposition method.•Structure and morphology of investigated photocatalysts were thoroughly analyzed.•The photocatalysts were examined for CO2 photocatalytic reduction in gas phase.•Enhanced photocatalytic activity of photocatalyst can be attributed to the low electron-hole recombination.
