The aim of this research is to improve the photocatalytic efficiency by implementation of titaniumdioxide nanowires/reduced graphene oxide (TiO2NWs/RGO) hybrid photocatalyst for dye degradation.The hybrid photocatalyst TiO2NWs/RGO was prepared using fabrication method. The physico-chemicalproperties of the photocatalyst was investigated by FTIR, XRD, SEM TGA, BET and their photocatalyticefficiency was evaluated for methyl orange degradation. Almost 100% of methyl orange was degradedby TiO2NWs/RGO hybrid photocatalyst under UV light within 210 min using 1.0 g at initialconcentration of methyl orange were 10 and 20 ppm. This is due to the 1D/2D heterostructures ofTiO2NWs/RGO hybrid photocatalyst that leads to the larger surface area, unique morphological andcrystallinity properties, as well as excellent mobility of charge carriers and thermally stable structure
