Metal free, carbon-TiO2 based composites for the visible light photocatalysis

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...
