Tóm tắt

This study emphasizes the critical importance of using surfactant-free gold nanoparticles to gain mechanistic insights and improve the energy efficiency and carbon monoxide selectivity in aqueous carbon dioxide reduction electrocatalysis. We utilized pulsed laser in liquid synthesis to prepare surfactant-free gold nanoparticles with a nonequilibrium cauliflower morphology, which demonstrated superior catalytic performance compared to conventionally synthesized citrate-capped gold nanoparticles. By functionalizing gold nanoparticles with nine
