Solar Photocatalytic reduction of carbon dioxide using TiO2 doped with copper powder to hydrocarbon have high selectivity for methane because of the presence of copper in the catalyst system. This process has attracted a lot of research for the past decade because of two major global challenges which are; the rapid increase of CO2 in the atmosphere resulting to global warming and the depletion of fossil fuel resulting to a search for renewable alternative source of energy. The process has been described as carbon capture and utilization and as artificial photocatalysis. With excess CO2 and deionized water, the volume of methane produced was 7.51cm3 through a TiO2/Cu catalyst system coated on aluminum support. The result was confirmed by flammability test and perception test.
