Abstract

In the present research work, copper nanoparticles were synthesized using 2.5% sodium dodecyl sulfate (SDS) as stabilizer in an aqueous solution with a pH of 5.66, and they were dispersed on two types of carbon supports with the aim of being used in the electrochemical reduction of CO2 to obtain products with greater added value. The nanoparticles obtained showed electrocatalytic activity in the CO2 reduction reaction. During the electroreduction of CO2, some products, such as formate and methanol, were detected. Using SEM, a change in the arrangement of the copper nanoparticles on the support was observed after 45 minutes of reaction, and through electrochemical analysis, an increase in current density was observed.
