Copper-Zinc-1,3,5-benzenetricarboxylic acid metal-organic frameworks, CuZn-MOF were synthesized using ZIF-8 as a template, and then the catalysts were calcination at high temperature with nitrogen (N2) supply through into pyrolysis processes. Bimetallic-MOF (BM) and N-doping Bimetallic-MOF (NBM) based catalyst has advantages like uniformly distributed bimetallic ions, less tendency towards aggregation, and more stable interfacial sites. Therefore, BM and NBM, as the CO2 capturing agent, was deposited on a working electrode and was used as cathodes to reduce CO2 to CO, and CH4. In our study, the electrochemical reduction CO2 (ERC) was taking place on an H-type cell in 0.1 M KHCO3 aqueous solution; the results shows without nitrogen-doped the higher with the BM-n (n= 3-4) addition on the surface of a working electrode, and with nitrogen-doped into the samples at 700oC (NBM1-700) shows Faradaic efficiency to CO as high as ~90%. |
