High-loading Au nanoparticles on carbon by engineering surface charge and specific surface area of substrates

Energy transition towards net-zero society calls for utilization of renewable power to drive CO2 conversion in an efficient electrochemical way.The development of a commercial CO2 electrolyzer with positive tech-eco effect calls for active and durable electrocatalysts.High-loading gold on carbon(Au/C)with reduced particle size is the prerequisite for the highly-selective and highly energy-efficient CO production in such a CO2 electrolyzer,but a scalable synthetic method is missing.With combined control of ligand,substrate and pH value,Au/C catalysts with particle size within 5 nm and metal loading of 40 wt%and 60 wt%are synthesized on low and high surface-area carbon,respectively.We also provide a thorough investigation of the effect of the ligand type,surface charge of gold nanoparticles(Au NPs)and surface area of carbon substrate on the loading limit of Au/C.
