Accelerating multielectron reduction at CuxO nanograins interfaces with controlled local electric field

Involved Members: Dr. Xue WANG, Dr. Ruquan YE

In this study, Cu_xO bipyramids with controlled tip angles and abundant nanograins were synthesized using laser-assisted manufacturing. The relationship between electron transport/ion concentrations and electrocatalytic performance was investigated through various tests and simulations. The results demonstrated the contributions of a strong electric field at the sharp tip and provided insights into the dynamic evolution of critical *CO/*OCCOH intermediates and product profiles. By modulating electron transport and ion concentrations, high Faradaic efficiency was achieved for C₂+ products via CO₂RR and nitrate reduction reaction (NITRR), showcasing the potential for carbon-nitrogen cycling.
