The transformation of CO2 into value-added products is a hot research topic. Metal copper as an electrochem. catalyst shows activity for generating multi-carbon products in CO2 electroreduction Herein, Cu2S nanorods/copper mesh (Cu2S/CM) is successfully fabricated, and exhibits high performance of CO2 electroreduction to ethanol. At -0.8 V vs RHE, it achieved the Faraday efficiency (FE) of 13.5%, the partial c.d. of 13.3 mA cm-2 and the yield of 986.4μmol L-1 h-1 for ethanol. Experiments and theor. calculations indicated that the high performance is benefits from the high d. of Cu0 and Cu + pairs derived from Cu2S/CM during CO2 electroreduction and an appropriate surface Cu0/Cu + ratio of 0.17. The Cu0-Cu+ sites facilitate the adsorption of key intermediate *CH2CHO and decrease the energy barrier of the ethanol pathway. This work provides not only a new comprehension of CO2 electroreduction with Cu2S catalyst but also a design idea based on Cu0-Cu+ sites in Cu/Cu2S catalyst. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Quality Control of Cuprichydroxide).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. Copper has continued to be one of the most utilized and important transition metal catalysts in synthetic organic chemistry. The copper-mediated C-C, C-O, C-N, and C-S bond formation is a part of one oldest reaction, emphasizing the Ullmann cross-coupling reaction.Quality Control of Cuprichydroxide
