摘　　要：A general method is developed to prepare durable hybrid nanocatalysts by nanostructuring the surface of gold wires via simple alloying and dealloying. The resulting nanoporous gold/Au （NPG/Au） wire catalysts possess nanoporous skins with their thicknesses on robust metal wires specified in a highly controllable manner. As a demonstration, the as-obtained NPG/Au was shown to be a highly active, chemo-selective, and recyclable catalyst for the reduction of nitro com- pounds and azides using organosilanes as reducing agents.一个一般方法被开发由 nanostructuring 准备持久的混合 nanocatalysts 经由简单 alloying 和 dealloying 的金电线的表面。产生 nanoporous gold/Au NPG/Au 电线催化剂在以一种高度可控制的方式指定的柔韧的金属电线上与他们的厚度拥有 nanoporous 皮肤。作为示范，同样获得的 NPG/Au 被显示是一高度活跃， chemo 选择，并且为把 organosilanes 用作减少代理人的 nitro 混合物和叠氮化物的减小的 recyclable 催化剂。
