▎ 摘　　要

A novel Cu/graphene nanocomposite catalyst was successfully prepared by a clean glucose-blowing method. In situ formation of Cu nanoparticles and graphene was accomplished through simplified process, which is environmental friendly and energy-saving. The morphology and structure of the Cu/ graphene nanocomposite was characterized by X-ray diffraction (XRD), Raman spectroscopy (Raman), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The results revealed that the Cu nanoparticles were densely deposited on graphene. The prepared Cu/graphene nanocomposite exhibited high catalytic activity with good cycling stability for the reduction of pnitrophenol (4-NP) to p-aminophenol (4-AP). 4-NP was efficiently reduced under green and mild condition.
