US Patent 10161051 Electrochemical reduction of CO2 at copper nanofoams

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.
