详细
A test study of a hydrophobized gas diffusion electrode with a tin catalyst deposited on acetylene black A437E was carried out in order to identify its potential for intensifying the process of electroreduction of CO2 to formate in acidic and alkaline aqueous solutions. Porous electrodes with a fluoroplastic content of 40 wt. %, thickness 0.5 mm, porosity 60 vol. % and tin content ≈0.7 mg/cm2, relative to the overall surface of the electrode were studied. It has been shown that, on this type of electrodes, it is possible to carry out the electroreduction of CO2 at a current density of up to 900 mA/cm2, at temperatures of 25–55°C with a formate flow yield of 74 to 96%. Electrolysis for 4 hours with a current density of 190 mA/cm2 resulted in a solution of potassium formate with a concentration of 1.58 M. In this case, an increase in the capacity of the double electrical layer was observed from 7 to 17 mF/cm2 and a decrease in current efficiency from 96 to 58%.
