In situ synthesis of Cu sub(2)O and Cu nanoparticles during the thermal reduction of copper foil-supported graphene oxide

This work describes a novel method to prepare reduced graphene oxide (rGO) sheets decorated with copper oxide and copper nanoparticles, by annealing copper foil-supported graphene oxide (GO) under an Ar atmosphere.

Description
Summary:This work describes a novel method to prepare reduced graphene oxide (rGO) sheets decorated with copper oxide and copper nanoparticles, by annealing copper foil-supported graphene oxide (GO) under an Ar atmosphere. The GO reduction level, the predominant Cu or Cu sub(2)O compound, and the particle size strongly depend on the process temperature. Scanning electron microscopy and X-ray diffraction analysis revealed that rGO-Cu sub(2)O and rGO-Cu nanocomposites developed on the Cu foil surface at the annealing temperatures of 200-600 and 800-1000 degree C range, respectively. Raman spectroscopy corroborates the effective GO reduction.
