The efficient catalysis of ethanol oxidation (EOR) is paramount importance for the progress energy conversion and storage technologies. We investigate improved catalytic performance commercial J-M Pt/C Pd/C catalysts by utilizing high potential scanning. By employing in situ Raman spectroscopy, we analyze reaction intermediates during electrochemical reactions. Our findings highlight that catalyst exhibits remarkable enhancements activity stability, which can be attributed to activation at potentials on electrode. Interestingly, different results are observed between under same experimental conditions. This study provides valuable insights into design development oxidation.
