Promoting Electrocatalytic Reduction of CO2 to C2H4 Production by Inhibiting C2H5OH Desorption from Cu2O/C Composite

Abstract: CO 2 RR) is regarded as one of the most attractive, which can not only convert CO 2 to high value hydrocarbon as fuels or chemical raw materials with high yields, but also be easily compatible to renewable energies. [2][3][4] Various hydrocarbons, that is, CO, HCOOH, CH 4 , C 2 H 4 , C 2 H 5 OH, etc., can be obtained during the CO 2 RR process. Among these products, multicarbon products (C 2+ ) are more attractive because of their higher economic values and higher energies densities with comparison to mono-car… Show more

“…These suggest that the Cu 2 O component did not undergo repeated oxidation processes, which is consistent with the results reported in other studies. 12,35 By comparing the XPS spectra and current− voltage curves, we observed a gradual decrease in Cu I (Figure 4d) accompanied by a decline in current density (Figure 4a). Obviously, Cu I species play a more crucial role in the formation of C 2 products.…”

“…Electrochemical CO 2 reduction is an attractive route for converting CO 2 to value-added chemicals (e.g., CO, [1][2][3][4] HCOOH, [5,6] C 2 H 4 , [7,8] and C 2 H 5 OH [9] ) using renewable energy (e.g., wind and solar energy). [10] CO, one of the most fundamental chemical feedstock and intermediate, is a potentially reduced product due to its high production rate and selectivity, especially for operations at industrial current densities (>200 mA cm −2 ).…”
