摘要: 以泡沫镍为基体,AuCl3为沉积液,应用快速自沉积法制备了泡沫镍负载的纳米Au/Ni电极.电化学方法测定AuCl3溶液的浓度和沉积时间对Au粒子的尺寸和分布以及以该电极作为Al-H2O2半燃料电池阴极对H2O2性能的影响.实验表明,泡沫镍经2mmol·L-1AuCl3溶液浸渍60s后,其表面完全被粒径小于100nm的Au粒子覆盖;以其为阴极的Al-H2O2半燃料电池,在0.4mol·L-1H2O2溶液中峰值功率达135mW·cm-2.

Abstract: Nano-sized Au particles were deposited on a nickel foam substrate by a fast spontaneous deposition method using AuCl3 as the source of Au. The effects of AuCl3 concentration and deposition time on the size and distribution of Au particles,and the performance of the obtained Au/Ni electrode as the cathode of Al-H2O2 semi fuel cell were investigated. It was found that after the nickel foam was immersed in a 2 mmol·L-1 AuCl3 solution for 60 s,Au particles with diameters smaller than 100 nm were deposited on its surfaces and cover the surface completely. The Al-H2O2 semi fuel cell with Au/Ni cathode shows a peak power density of 135 mW·cm-2 when operating in 0. 4 mol·L-1 H2O2 solution at room temperature.

Key words: Au nanoparticles, hydrogen peroxide electroreduction, cathode, metal semi fuel cell
