Can the CO2Reduction Reaction Be Improved on Cu
Abstract
<p>Cu is currently the most effective monometallic catalyst for producing valuable multicarbon-based (C<sub>2+</sub>) products, such as ethylene and ethanol, from the CO<sub>2</sub>reduction reaction (CO<sub>2</sub>RR). One approach to optimize the activity and selectivity of the metal Cu catalyst is to functionalize the Cu electrode with a molecular modifier. We investigate from a data standpoint whether any reported functionalized Cu catalyst improves the intrinsic activity and/or multicarbon product selectivity compared to the performance of bare Cu foil and the best single crystal Cu facets. Our analysis shows that the reported increases in activity are due to increased surface roughness and disappear once normalized with respect to electrochemical surface area. The intrinsic activity generally falls below that of the bare Cu foil reference, both for total and product-specific current, which we attribute to nonselective blocking of active sites by the modifier on the surface. Instead, an analysis of various polymer diffusion coefficients indicates that the modifier allows for easier diffusion of CO<sub>2</sub>compared to H<sub>2</sub>O to the surface, leading to greater selectivity for CO<sub>2</sub>RR and C<sub>2+</sub>products. As such, our analysis finds no catalyst for CO<sub>2</sub>RR that intrinsically outperforms bare Cu.</p>
