Copper Catalyst

Caption

Schematic of a two-layer coating of films, called ionomers, on top of a copper surface. The negatively charged ionomer, Nafion, raises the pH near the surface. The positively charged ionomer, Sustainion, more strongly attracts CO2. These effects combined with a pulsed voltage result in substantially enhanced rates of CO2 conversion to valuable carbon-rich products.
