摘要
采用溶胶凝胶法制备了纳米SnO2,并用浸渍-还原方法合成Pt-SnO2/C催化剂;用X射线衍射仪对助催化剂纳米SnO2 进行结构表征,并在酸性介质中对所制备的Pt-SnO2/C工作电极进行循环伏安测试.结果表明,纳米SnO2 可以通过助催化的方式提高Pt催化剂电催化氧化甲醇的能力.
Abstract
Tin dioxide nanoparticles were prepared through the Sol-Gel method and were mixed with Pt black catalysts physically for Pt-SnO2/C which was synthesized by dipping-reduction method;Surface morphology and composition of the resulting electrocatalysts were studied by means of XRD,The electrochemical catalytic activity of the working electrode prepared Pt-SnO2/C was tested by cyclic voltammetry in acidic medium.The results showed that Tin dioxide can improve the catalytic oxidation of methanol by Pt catalyst.
