Randomized trial investigates C2+ production in boron-doped copper nanoparticles, suggesting a novel method for effective electrochemical reduction of CO2.
Key Points
This study aims to enhance the selectivity of copper nanoparticles for the electrochemical reduction of carbon dioxide to multi-carbon products by regulating the local environment.
Preparation of boron-doped copper nanoparticles with defects
Electrochemical analysis in neutral electrolyte
Density functional theory calculations to understand adsorption mechanisms
Boron-doped Cu nanoparticles achieved a Faradaic efficiency of approximately 75% for C2+ production.
Stability of the B-Cu-1 nanoparticles was maintained for up to 30 hours at -1.1 V (vs. RHE).
Enhanced adsorption of *CO intermediate was facilitated by B-induced defects, increasing C2+ pathway efficiency.
