Abstrakt: The construction of an efficient catalyst for electrocatalytic reduction of CO 2 to high value-added fuels has received extensive attention. Herein, nitrogen-doped mesoporous carbon (NMC) was used to support CuSb to prepare a series of materials for electrocatalytic reduction of CO 2 to CH 4 . The catalytic activity of the composites was significantly improved compared with that of Cu/NMC. In addition, the Cu content also influenced the activity of electrocatalytic CO 2 reduction reaction. Among the materials used, the CuSb/NMC-2 (Cu: 5.9 wt%, Sb: 0.49 wt%) catalyst exhibited the best performance for electrocatalytic CO 2 reduction, and the faradaic efficiency of CH 4 reached 35%, and the total faradaic efficiency of C1-C2 products reached 67%.
