The modified Hummers method is used to prepare graphite oxide (GO). Then reduced graphene oxide (rGO) and modified graphite oxide (NGO) are prepared by ascorbic acid reduction and ammonia solution modification, respectively. With GO, rGO, and NGO as the support, Cu or Ni mono-metal and CuNi bi-metals are support as M-GO, M-rGO, and M-NGO (M: Cu, Ni, and CuNi), respectively. FTIR, XPS, and TEM are used to analyze the properties and microstructure of the resulting composites. Up to 60% of Cu2+ can be reduced, and copper grains are evenly dispersed on the support. Cu2+ reduction can be promoted by support reduction, ammonia modification, and nickel addition. The reduction degree of copper is related to the size of copper crystal.
