Overcoming Copper Stability Challenges in Co2 Electrolysis

Raffaella Buonsanti, Petru Pasquale Albertini, Jari Leemans

Copper and copper-based catalysts can electrochemically convert CO2 into ethylene and higher alcohols, among other products, at room temperature and pressure. This approach may be suitable for the production of high-value compounds. However, such a promisi ...

The Chemical Nature of the Oxide Directs the Stability and Reactivity of Copper|Oxide Interfaces in the Electrochemical CO2 Reduction Reaction

Raffaella Buonsanti, Krishna Kumar, Petru Pasquale Albertini, Coline Marie Agathe Boulanger, Jari Leemans

Understanding the impact of composition and interfaces between metals and oxides is a goal of interest for many chemical reactions. Herein, we propose a framework to map correlations between the electrochemical behavior of the oxide and the stability and r ...
