We fabricate TiO2 nanostructures on reduced graphene oxide (RGO) film for low cost and high-performance electric device. RGO sheet is made by Hummus method that allows for the formation of graphene sheet from graphite. Nanostructured polymer template constructed via interference lithography is removed at high temperature (500℃) after the infiltration of titanium dioxide precursors. TiO2 nanostructures on graphene sheets have a great potential for the applications of cost-efficient and high-performance solar cells and secondary batteries.
