Experimental Verification of Mixed-potential-driven Catalysis

Mixed-potential-driven catalysis could be a novel strategy to control catalytic selectivity. In this mechanism, anodic and cathodic reactions occur simultaneously, forming mixed potential on the nano-anode nano-cathode composed of supported catalyst. To prove mixed-potential-driven catalysis, we developed new model reactor with separated electrodes directly measure currents between under high-pressure conditions. We observed that reaction mixed-potential only when CO2/H2 mixture was introduced into Cu Pd without separating CO2 H2. This indicates reduction H2 oxidation occurred simultaneously catalysts, respectively, based activity via mechanism. The products for 18 h at 373 K were CO, methanol, ethanol.
