开发了一种具有宽银浓度范围的新型钙银金属玻璃。在温和条件下，即在自由腐蚀条件下，将Ca-Ag非晶合金在水中脱合金化，制备出纳米多孔银。所得的纳米多孔银显示出可调的韧带尺寸，高的表面积，和良好的电化学催化活性的甲醛的氧化。该方法合成的纳米多孔银在催化、传感器等方面具有潜在的应用价值。(C)2015爱思唯尔有限公司版权所有。
A family of novel Ca-Ag metallic glasses with a wide range of Ag concentration was developed. Nanoporous silver was fabricated under mild conditions, i.e. the dealloying of the Ca-Ag metallic glasses in water under free corrosion conditions. The resulting nanoporous silver shows tunable ligament size, high surface area, and good eletrochemical catalytic activity for the oxidation of formaldehyde. The nanoporous silver synthesized by the convenient route is significant for potential applications in catalysis, sensors, etc.. (C) 2015 Elsevier Ltd. All rights reserved.
