  • Publication number: 20240328011
    Abstract: The present disclosure relates to a gold nanocluster catalyst for carbon dioxide conversion represented by [Chemical Formula 1] and a method for preparing the same: Aun(SR)m??[Chemical Formula 1] wherein SR is an organic thiol-based ligand containing an anionic terminal group, n is an integer between 25 and 102 and m is an integer between 18 and 44. Since the gold nanocluster catalyst according to the present disclosure has superior carbon dioxide conversion activity, the gold nanocluster catalyst may be used for a gas diffusion electrode.
