We present and discuss new results on the selective photocatalytic conversion of CO2 and H2O into CH4 based on a metal-semiconductor system involving low-cost nanostructures of TiO2 deposited on metal substrates. Such a system was found to be promising for reforming CO2 using solar energy. By fine-tuning the structural and optical properties of the various photo reactor components, a high selectivity and high yield for photocatalytic conversion of CO2 into CH4 are observed.
