A simple and scalable synthetic approach for one-step synthesis of graphene–Cu O(TRGC) nanocomposite by an in situ thermo-annealing method has been developed.Using graphene oxide(GO) and copper hydroxide as a precursors reagent,the reduction of GO and the uniform deposition of in situ formed Cu O nanoparticles on graphene was simultaneously achieved.The method employed no solvents,toxic-reducing agents,or organic modifiers.The resulting nanostructured hybrid exhibited improved H2 S sorption capacity of 1.5 mmol H2S/g-sorbent(3 g S/100 g-sorbent).Due to its highly dispersed sub-20 nm Cu O nanoparticles and large specific surface area,TRGC nanocomposite exhibits tremendous potential for energy and environment applications.
