Functionalization of Pd and Ni catalysts with nanoporous structure

采用脱合金法制备了纳米多孔钯和纳米多孔镍。贵金属在合金/电解质界面的扩散对纳米孔结构的形成起重要作用；标准电极电位的差异并不总是允许不太贵重的元素溶解（以及随后的纳米孔隙演化）。并对合成的纳米多孔钯和镍的催化性能进行了评价。

Nanoporous Pd and Ni were successfully fabricated by dealloying(selective dissolution from binary alloys). The diffusion of nobler metals at alloy/electrolyte interface plays an important role in the formation of nanoporous structure ; the difference in the standard electrode potential does not always allow the dissolution of less noble element(and subsequent nanoporosity evolution). Also, catalytic properties of synthesized nanoporous Pd and Ni were evaluated.
