Defective Cu-Bi catalysts promote co-reduction of N2 and CO2 to urea

Reporting in this issue of Chem Catalysis, Wu et al. developed a defective Cu-Bi catalyst that can promote co-reduction of CO2 and N2 to urea. The defective Cu-Bi catalyst reports up to 0.45 mg L−1 of urea with a Faradaic efficiency of 8.7% under ambient conditions, paving the path toward clean urea production.
