Abstract Scope |
This work presented the development of an electrocatslyst to reuse the CO2 for fuel formation via electrochemical CO2 reduction reaction (CO2RR). In this study, we synthesized a bimettalic indium-tin metal-organic framework (MOF) by solvothermally method. The resulting catalysts were characterized by XRD, SEM, EDX, BET and FTIR. The EDS offers 1.8 wt.% loading into the Tin-MOF, which is less than the theoretical add value (2.0 wt.%). Using a catalyst ink dissolved in isopropanol on carbon paper, a functional electrode was prepared on conductive carbon paper. The LSV, CV and EIS of In-Sn-MOF shows higher current density and higher conductivity compare to the prestine Sn-MOF. NMR analysis of the liquid product revealed only formic acid. The quanitittvie results revealed the formation of formic acid with the highest Faradic Effeciency (FE) of 70 % at -1.1 vs RHE and a higher partial current density compare to the prestine Sn-MOF. |
