## Description

- description: Electrolytic synthesis of energy carriers using renewable energy and
    fuel cells that use energy carriers for regeneration are important technologies
    for achieving our carbon-neutral society. However, electrochemical reactions in
    electrolyte containing organic molecules significantly degrades the electrodes
    by catalyst poisoning (i.e. polymerization of organic molecules on the electrode
    surface). Such situation can easily occur through the crossover phenomenon between
    the anode and cathode chambers. Thus, the understanding of the electrochemical
    reactivity of organic molecules on electrodes becomes important for utilizing
    energy carriers. This study investigated the electrochemical reactivity of various
    organic molecules with typical functional groups to understand the reaction mechanism
    and the subsequent catalyst poisoning in acidic media. While −OH groups on organic
    molecules do not cause significant degradations on a non-noble metal high entropy
    alloy anode, the coexistence of −NH2 and C = O groups on organic molecules significantly
    degrades the anode because the generated polymers block the catalytically active
    sites. This knowledge will contribute to the effective design of catalysts/electrodes,
    and benefit the communities in electrolytic synthesis and fuel cells.
