Electrochem. reduction of carbon dioxide is an attractive and challenging strategy to solve the problems of renewable energy storage and carbon neutral. However, activity, selectivity, and stability of present developing catalysts for production of C2H4 are not as high as required for practical applications. Herein, we report dezincified copper nanowires (pre-CuZn-CuNW) derived from an electrodeposited CuZn alloy by a wet chem. method for electrochem. reduction of carbon dioxide to C2H4. Compared with pre-Cu-CuNW (the copper nanowires derived from a bulk Cu), the pre-CuZn-CuNW significantly enhances the catalytic activity and the selectivity for C2H4. The partial normalized c.d. of the pre-CuZn-CuNW for production of C2H4 increases to 183 mA.cm-2, which is about twice relative to pre-Cu-CuNW. The faradaic efficiency (FE) of the pre-CuZn-CuNW for C2H4 can be maintained over 46% for 24 h during carbon dioxide reduction reaction. The improved catalytic performance can be attributed to the formation of a special nanowire structure with larger electrochem. active surface area and higher intrinsic activity of the pre-CuZn-CuNW during the dealloying process. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2COA of Formula: CuH2O2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. Transition metal-catalyzed chemical transformation of organic electrophiles and organometallic reagents belong to the most important cross-coupling reaction in organic synthesis. 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.COA of Formula: CuH2O2
