Photoinduced reactions on titania has received considerable attention due to their potential applications in dye sensitized solar cells, photosplitting of water to hydrogen, photo catalytic self-cleaning surfaces etc. The photocatalytic reduction reactions in which conversion of carbon dioxide to hydrocarbons using titania nanostructures are an important and emerging area of inquiry with respect to solar fuel production. The objective of the present work is to explore the effect of different types of titania nanostrucutres such as nanotube, nanorods, nanosheets and composites with graphene and carbon nanotubes for the photocatalytic reduction of carbon dioxide to fuel. It was found that photoactivity is highly dependent on the morphology and the mass ratio of the composites. Further, these composites are effectively used for photoreduction under visible light, which leads to the possible application of these catalysts for solar energy conversion to fuel.
