Utilisation of carbon dioxide and nitrate for urea electrosynthesis with a Cu-based metal–organic framework

Abstract

It is important and challenging to utilise CO2 and NO3 as a feedstock for electrosynthesis of urea. Herein, we reported a stable 2D metal–organic framework (MOF) Cu-HATNA, possessing planar CuO4 active sites, as an efficient electrocatalyst for coupling CO2 and NO3 into urea, achieving a high yield rate of 1.46 g h−1 gcat−1 with a current density of 44.2 mA cm−1 at −0.6 V vs. RHE. This performance surpasses most of the previously reported catalysts, revealing the great prospects of MOFs in sustainable urea synthesis.
