In situ spectroscopic study of CO2 electroreduction at copper electrodes in acetonitrile
Abstract
<p>The electrochemical conversion of carbon dioxide (CO<sub>2</sub>) into valuable compounds is a promising route toward the valorization of this molecule of high environmental impact. Yet, an industrial process involving CO<sub>2</sub> electroreduction is still far from reality and requires deep and fundamental studies for a further understanding and better development of the process. In this work, we describe in situ spectroelectrochemical studies based on Fourier transform infrared spectroscopy and surface-enhanced Raman spectroscopy of the CO<sub>2</sub> reduction in acetonitrile solutions at copper electrodes. The influence of factors such as the water content and the supporting electrolyte on the reaction products were evaluated and compared to products obtained on metal electrodes other than Cu, such as Pt, Pb, Au, Pd, and Ag. The results show that at Cu electrodes in acetonitrile containing small amounts of water, the main reaction products from CO<sub>2</sub> reduction are carbonate, bicarbonate, and CO. The formation of CO was observed at less-negative potentials than the formation of (bi)carbonates, and the formation of carbonate and bicarbonate species appears to be the result of a reaction with electrochemically generated OH<sup>-</sup> from water reduction. In general, our experiments show the sensitivity of the CO<sub>2</sub> reduction reaction to the presence of water, even at the residual level. (Chemical Equation Presented).</p>
