000150641 5203_ $$aPhotocatalytic gas-phase hydrogenation of CO2into alkanes was achieved over TiO2-supported Ni nanoparticles under LED irradiation at 365 nm, 460 nm and white light. The photocatalysts were prepared using photo-assisted deposition of Ni salts under LED irradiation at 365 nm onto TiO2P25 nanoparticles in methanol as a hole scavenger. This procedure yielded 2 nm Ni particles decorating the surface of TiO2with a nickel mass content of about 2%. Before the photocatalytic runs, Ni/TiO2was submitted to thermal reduction at 400 °C in a 10% H2atmosphere which induced O-defective TiO2-xsubstrates. The formation of oxygen vacancies, Ti3+centers and metallic Ni sites upon photocatalytic CO2hydrogenation was confirmed byoperandoEPR analysis.In situXPS under reaction conditions suggested a strong metal-support interaction and the co-existence of zero and divalent Ni states. These photoactive species enhanced the photo-assisted reduction of CO2below 300 °C to yield CO, CH4and C2H6as final products.
