The high increase of carbon dioxide (CO2) emissions to the earth’s atmosphere during the last decades has become an issue of global concern, since CO2 is one of the major contributors to the greenhouse effect. [1] The electrochemical conversion of CO2 into high-value chemicals and fuels is a promising pathway toward the mitigation of the environmental impact of CO2 and to its valorization as an alternative energy source.
Copper has been widely studied as an electrocatalyst for electrochemical CO2 reduction reaction (CO2RR), because of its potential to generate significant amounts of hydrocarbons at high reaction rates [2][3]. In this contribution, we present a study of a sulfide-derived copper catalyst for CO2 reduction, using different structural characterization techniques (SEM, DRX and TEM) to understand the electrochemical properties of this material toward CO2 reduction. Consequently, a detailed voltammetric and electrochemical impedance spectroscopy (EIS) analysis on this system in aqueous electrolyte is reported to determine the adsorbed species during the CO2RR.
