Electrochemical CO₂ Reduction: Classifying Cu Facets

For CO2 reduction reactions, the Cu catalyst is unique, as compared with other metals, because of its ability to produce a wide range of hydrocarbon and oxygenated products. Previously, we have shown that Cu has the unique property of binding CO* without having H* UPD (underpotential deposited). However, the product distribution from Cu depends highly on the exact nature of the Cu surface. In this work, we investigate a series of Cu facets to...
