我们报道了从Ag-Al合金中选择性溶解Al制备的纳米多孔银的可逆尺寸变化。在0.5 M NaOH中的循环伏安法实验期间记录了类似于0.2和0.5%之间的应变振幅。这些可逆的位移是可比的，如果不高于，在类似的实验条件下，在最高贵的纳米多孔金属，如Pt和Au的报告。我们的新发现表明，银可能是一个很好的候选材料，低成本的电化学驱动应用。(C)2013 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
We report on reversible dimensional changes in nanoporous silver made by selective dissolution of Al from Ag-Al alloys. Strain amplitudes of between similar to 0.2 and 0.5% were recorded during cyclic voltammetry experiments in 0.5 M NaOH. These reversible displacements are comparable to, if not higher than, those reported in the noblest nanoporous metals such as Pt and Au under similar experimental conditions. Our new findings indicate that Ag could be a good candidate material for low-cost electrochemical actuation applications. (C) 2013 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
