Urea electrosynthesis provides an intriguing strategy to improve upon the conventional urea manufacturing technique, which is associated with high energy requirements and environmental pollution. However, the electrochem. coupling of NO3– and CO2 in H2O to prepare urea under ambient conditions is still a major challenge. Herein, self-supported core-shell Cu@Zn nanowires are constructed through an electroreduction method and exhibit superior performance toward urea electrosynthesis via CO2 and NO3– contaminants as feedstocks. Both 1H NMR spectra and liquid chromatog. identify urea production The optimized urea yield rate and Faradaic efficiency over Cu@Zn can reach 7.29μmol cm-2 h-1 and 9.28% at -1.02 V vs RHE, resp. The reaction pathway is revealed based on the intermediates detected through in situ attenuated total reflection Fourier transform IR spectroscopy and online differential electrochem. mass spectrometry. The combined results of theor. calculations and experiments prove that the electron transfer from the Zn shell to the Cu core can not only facilitate the formation of *CO and *NH2 intermediates but also promote the coupling of these intermediates to form C-N bonds, leading to a high faradaic efficiency and yield of the urea product. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Safety of Cuprichydroxide).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The applications of Copper-based nanoparticles have received great attention due to the earth-abundant, inexpensive and low toxicity. Due to these characteristics, copper nanoparticles have generated a great deal of interest especially in the field of catalysis. Safety of Cuprichydroxide
