ELECTROCHEMICAL REDUCTION OF CO2 AT COPPER NANOFOAMS |
摘要 |
This invention includes a catalytic copper electrode is selected from the group comprising copper nanofoam, copper aerogel, and copper nanoparticles. Particular note is made of the catalytic copper electrode having at least about 5 times and preferably about 10 times the electrochemically accessible surface area as determined by the Randles-Sevcik equation at 50 mV/s. particular note is made of the catalytic coper electrode being a copper nanofoam electrode. This invention further includes a method for the reduction of C02 by the steps of (i) providing a membrane divided electrochemical cell comprising an anode in a first cell compartment, a catalytic-copper electrode in a second cell compartment containing an aqueous electrolyte in contact with the anode and cathode; (ii) introducing C02 to said second cell compartment (iii) exposing said C02 to said catalytic-copper electrode at a step potential between about -0.8 and preferably about -1.0 and about -1.8 V versus the reference electrode; (iv) electrochemically reducing said C02 and solution by the catalytic-copper electrode in the second cell compartment; (v) thereby producing propylene and (vi) extracting said propylene from said second compartment. |
