Tracking heterogeneous structural motifs and the redox behaviour of copper-zinc nanocatalysts for the electrocatalytic CO2 reduction using operando time resolved spectroscopy and machine learning

Martina Ruescher et al.

Summary: Copper-based catalysts are widely used for the electrocatalytic CO2 reduction reaction (CO2RR) to convert CO2 into valuable industrial chemicals. Bimetallic materials, such as ZnO/Cu2O nanocubes, show promising catalytic performance for CO2RR. In this study, operando spectroscopy and data analysis were used to investigate the chemical and structural changes of the catalysts under CO2RR conditions. It was found that the addition of Zn affects the kinetics of subsurface processes, while the Cu surface layer remains unchanged. The presence of Zn stabilizes cationic Cu(i) species and increases the selectivity towards C2+ products, while Zn-rich alloy phases promote the formation of CO and the parasitic hydrogen evolution reaction.
