Improved interfacial charge transfer and visible light activity of reduced graphene oxide-graphitic carbon nitride photocatalysts

Development of efficient visible light-driven photocatalysts is an important approach towards sustainability. Herein, reduced graphene oxide-graphitic carbon nitride (rGO-gCN) photocatalysts were successfully prepared by in situ photocatalytic reduction of graphene oxide (GO) in the presence of gCN...
