The CV measurements for the CO2RR showed that the Znā??Ni bimetallic electrocatalyst has a current density of 8.4 mA cmā??2 and overpotential of ā??130 mV vs. Ag/AgCl. The gas chromatography results presented that the Znā??Ni bimetallic electrocatalyst produced an appropriate amount and ratio of CO (55) and H2(45) among other electrocatalysts in this study. SEM and EDX results demonstrated that after 48 h of testing for the CO2RR, the Znā??Ni electrocatalyst had the lowest coke formation among the other electrocatalysts. The microstructure of electrocatalyst for the CO2RR plays a key role, so in this respect, the cluster microstructure of the Znā??Ni electrocatalyst has a more suitable performance than the Znā??Niā??Co electrocatalyst with spherical microstructure. Since the cluster microstructure of Znā??Ni provides more catalyst activation points for the electrocatalyst and less binding energy with intermediate molecules for CO2RR, therefore it is still effective for CO2RR after 48 h, with low coke formation and high efficiency.
