这项工作报告了金属玻璃前体对纳米多孔金属催化性能的影响。以Pd20Ni60P17B3和Pd20Ni20Cu40P17B3金属玻璃为前驱体，在临界脱合金电位下，通过电化学脱合金制备了具有相似纳米孔结构的Pd基多元纳米孔金属.结果表明，不同化学组成的玻璃态前驱体导致所得纳米多孔金属中掺杂元素不同，从而导致不同的催化活性。
This work reports the effects of metallic glass precursors on the catalytic performance of nanoporous metals. Pd-based multicomponent nanoporous metals with similar nanoporous structure were successfully fabricated by electrochemically dealloying the Pd20Ni60P17B3 and Pd20Ni20Cu40P17B3 metallic glass precursors at the critical dealloying potentials. It was found that the glassy precursors with different chemical compositions result in different doping elements in the as-obtained nanoporous metals and thus lead to different catalytic activities.
