Abstract

Palladium Pd/polyaniline (PANI) nanocomposite was prepared by a thermal reflux method as the catalyst for direct ethanol fuel cells. The Pd/PANI catalysts were characterized by using FTIR transmission electron microscopy techniques. The electrocatalytic performances of Pd/PANI catalysts for ethanol oxidation were studied by cyclic voltammetric measurement. It was found that, compared with Pd, the Pd/PANI catalyst showed superior electrocatalytic activity for ethanol oxidation when the mass ratio of Pd precursor salt to PANI was about 1:2.

Pd/PANI电催化氧化乙醇的研究

采用热回流法制备了钯钯/聚苯胺(PANI)纳米复合材料，作为直接乙醇燃料电池的催化剂。采用FTIR透射电镜技术对钯/聚苯胺催化剂进行了表征。采用循环伏安法研究了Pd/PANI催化剂对乙醇氧化的电催化性能。结果表明，当Pd前驱体盐与PANI的质量比为1:2时，Pd/PANI催化剂对乙醇氧化的电催化活性优于Pd。
