摘　　要：通过电弧炉和管式炉烧结制备不同原子比的铜锰合金前驱体,室温下在0.1mol/L盐酸溶液中对制备出的前驱体合金进行自腐蚀制备纳米多孔铜。采用SEM、EDS、Autosorb-1等分析了样品的表观形貌、元素含量和微观孔结构。结果表明:采用去合金法得到结构均匀的三维连通纳米多孔铜片体材料,管式炉制备的Cu:Mn原子比为3:7的样品获得相对分布更为均匀、孔结构更为明显的多孔铜。We prepared Cu - Mn alloy with different atomic ratio by press sintering process in the electric arc furnace and tube furnace respectively. The prepared samples were corroded freely to gain the nanopo- rous copper in 0.1 mol/L hydrochloric acid solution in the room temperature. The morphology, compo- nent, and pore structure of the dealloying samples were investigated by SEM, EDS, and pore structure an- alyzer. The results show inner - connected nanoporous copper materials were obtained by dealloying meth- od. And the dealloying nanoporous copper, which prepared by Cu - Mn alloy in 3：7 atomic ratio sintered by tube furnace, presented relative more uniform and had better pore structure distribution.
