In situ Raman study of high potential scan enhanced Pt/C and Pd/C catalyst performance for ethanol oxidation
The efficient catalysis of ethanol oxidation (EOR) is of paramount importance for the progress of energy conversion and storage technologies. We investigate the improved catalytic performance of commercial J-M Pt/C and Pd/C catalysts for ethanol oxidation by utilizing high potential scanning. By employing in situ Raman spectroscopy, we analyze the reaction intermediates during electrochemical reactions. Our findings highlight that the Pd/C catalyst exhibits remarkable enhancements in catalytic activity and stability, which can be attributed to the activation at high potentials on Pd/C electrode. Interestingly, different results are observed between Pt/C and Pd/C catalysts under the same experimental conditions. This study provides valuable insights into the design and development of efficient catalysts for ethanol oxidation.
期刊介绍：
Electrochemistry Communications is an open access journal providing fast dissemination of short communications, full communications and mini reviews covering the whole field of electrochemistry which merit urgent publication. Short communications are limited to a maximum of 20,000 characters (including spaces) while full communications and mini reviews are limited to 25,000 characters (including spaces). Supplementary information is permitted for full communications and mini reviews but not for short communications. We aim to be the fastest journal in electrochemistry for these types of papers.
