Co-doped Pd Nanocrystals for Efficient Electrosynthesis of Urea via C-N Coupling Reaction from Nitrate and CO2

Abstract

The electrocatalytic C-N coupling reaction between CO2 and nitrate to synthesize urea represents a promising green and environmentally friendly alternative to traditional energy-intensive urea production methods. In this study, we propose a the Co10-Pd@CF catalyst delivers an optimal urea production rate of 339.53 μg h-1 cm-2 with a current density of -15 mA cm-2 at an ultra-low overpotential of -0.15 V vs. RHE, while maintaining stable performance without activity degradation over 72 h of continuous operation.
