Graphene-carbon nanodots-TiO2 novel ternary composite was developed as visible light photocatalyst. Efficiency and visible light sensitivity of TiO2 for the photodecoloration were enhanced by carbon based photo-sensitizers i.e. carbon nanodots (c-dots) and support i.e. reduced graphene oxide (graphene). The c-dots were prepared by electrophoretic dissolution of graphite electrode in water. The hydrothermal method was used to prepare the composite of graphene, c-dots and TiO2. These were characterized by XRD, TEM and Raman spectroscopy. The activity of the composites was judged by photocatalytic decol-oration of methyl blue dye under visible light illumination. The enhanced photocatalytic activity has been attributed to the efficient photo-injection of electrons from c-dots to TiO2 along with superb ability of graphene to adsorb organic molecules as well electron sink from TiO2 for the photocatalysis.
