摘要
采用电沉积法制备Pt-Ru合金电极。研究了电解液中Pt和Ru的浓度对电极表面组成形貌和电催化活性的影响。实验表明,优化电解液中Ru的浓度,可使电极表面形成分布均匀的纳米级Pt-Ru合金,并表现出良好的电催化性能。采用环境扫描电子显微镜表征电极的表面形貌;采用能谱仪测定Pt-Ru电极的表面组成;采用循环伏安法测量Pt-Ru电极的电化学性能。
The Pt-Ru alloy electrodes were prepared using the electrodeposition method. The effects of the Pt and Ru contents in electrolytes on the physicochemical characteristics and electrocatalytic activity of electrodes were investigated. The results show that a surface with the nanometer-sized particles distributed are formed when the Ru content in the electrolyte is optimal, and the prepared Pt-Ru alloy electrode exhibits a good electrochemical property. The surface morphology of the Pt- Ru electrode was determined by ESEM; the surface composition of Pt-Ru electrode was measured by EDS; and the electrochemical characteristic was analyzed by CV method.
