For the first time, copper nanoparticles (Cu NPs) superficially deposited on reduced graphene oxide (rGO) using leaf aqueous media. A beneficial series of analytical methods was used to characterise leaf extract and involved nanostructures. The Cu/rGO nanocomposite (NC) obtained from the conversion of Cu ions to Cu NPs and GO to rGO undergoes the plant extract and used as a heterogeneous and reusable nanocatalyst for the destruction of 4-nitrophenol, rhodamine B, methylene blue, methyl orange and congo red using sodium borohydride at ambient temperature. In addition, Cu/rGO NC has reusability for many times in the reduction reactions with no decreasing of its catalytic capability.
首次使用叶片水介质在还原氧化石墨烯（rGO）表面沉积铜纳米颗粒（Cu NPs）。采用一系列有益的分析方法对叶片提取物和相关纳米结构进行表征。通过将铜离子转化为Cu NPs以及将氧化石墨烯（GO）转化为rGO而获得的Cu/rGO纳米复合材料（NC）经过植物提取物处理，并用作多相可重复使用的纳米催化剂，在室温下使用硼氢化钠来降解4-硝基苯酚、罗丹明B、亚甲基蓝、甲基橙和刚果红。此外，Cu/rGO NC在还原反应中具有多次可重复使用性，其催化能力不会降低。
