Nanowerk  November 17, 2021 A team of researchers in the US (UC Berkeley, Lawrence Berkeley National Laboratory) has improved the electrochemical reduction process for turning CO2 emissions into a fuel feedstock by developing a new approach to modify the surface of the copper catalysts used to assist the reaction. They applied a thin layer of Nafion and Sustainion, as well as a bilayer of both ionomers, to copper films supported by a polymer material, forming membranes that they could insert near one end of an electrochemical cell. For the two-layer case, they found that carbon-rich products accounted for 80% of […]
