采用去合金化法对Cu0.3Mn0.7合金进行自腐蚀制备出厚度为1mm的纳米多孔铜块体材料。采用XRD、SEM、EDS、AAS等分析了样品的相组成、微观形貌和元素含量。结果表明:样品在室温0.1mol/L盐酸溶液中自腐蚀10d,得到成分单一,结构均匀的三维连通纳米多孔铜块体材料,其表面平均孔径尺寸约125nm,平均骨架尺寸约80nm,横截面平均孔径尺寸约300nm。 The Cu0.3Mn0.7 alloy was self-eroded by de-alloying to prepare a porous copper block material with a thickness of 1mm. The phase composition, microstructure and elemental content of the samples were analyzed by XRD, SEM, EDS and AAS. The results showed that the samples were self-corroding for 10 days in 0.1 mol / L hydrochloric acid solution at room temperature. The three-dimensionally interconnected nanoporous copper block with single component and homogeneous structure was obtained. The average pore size was about 125 nm and the average framework size was about 80 nm. The pore size is about 300nm.
