摘　　要：在含有离子液体[BMIm]PF_6、[PMIm]PF_6和[C_6MIm]PF_6的介质中,通过还原Cu^(2+)制备铜纳米粒子。通过TEM和XRD分析,对比研究了Cu^(2+)浓度、还原剂种类以及离子液体[BMIm]PF_6、[PMIm]PF_6和[C_6MIm]PF_6对所制备的铜纳米粒子的粒径和形貌的影响。结果表明:Cu^(2+)浓度对铜纳米粒子的粒径和形貌没有明显的影响;离子液体的类型对铜纳米粒子的粒径也没有明显的影响,但对形貌有一定的影响;还原剂对铜纳米粒子的粒径及形貌影响较大,Cu nano-particles were prepared in the medium containing ionic liquids[BMIm]PF_6、[PMIm]PF_6 and [C_6MIm]PF_6 through reducing Cu^（2＋）.Influences of the Cu^（2＋） concentration,reducing agents types and ionic liquids [BMIm]PF_6,[PMIm]PF_6 and[C_6MIm]PF_6 on the particle size and morphology of the copper nano-particles were researched based on the analysis results of TEM and XRD.The results showed that the Cu^（2＋） concentration had no obvious influence on the particle size and morphology of the copper nano-particles,the ionic liquids types had no obvious influence on the particle size of copper nano-particles too,however,had certain influence on the morphology. The reducing agents had a great influence on the particle size of copper nano-particles.
