A method for preparing a highly active electrode supported by a metal on a binary support containing molecular sieves

摘要: The invention relates to a preparation method of highly active electrode loaded with metal nanoparticles on binary carrier containing molecular sieve. First all, consisting ofZSM-5 sieve and carbon black is prepared, then Pd were prepared by chemical reduction using palladium nitrate as raw material supported ZSM-5-C carriers, obtain Pd/ZSM-5-C composite, coat that surface the glassy electrode, drying at room temperature electrode. In wider ZSM-5:C mass ratio range, has significantly higher catalytic activity n-propanol oxidation reaction under alkaline medium condition than Pd/C Pd/ZSM-5 electrodes. It improved electrocatalyticactivity was addition zeolite-5 into support. composite issimple, improvement effect electrocatalytic remarkable, application prospect wide.
