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.

ABSTRACT: Copper-based catalysts are established catalytic systems for the electrocatalytic CO₂ reduction reaction (CO₂RR), where the greenhouse gas CO₂ is converted into valuable industrial chemicals, such as energy-dense C₂₊ products, using energy from renewable sources. However, better control over the catalyst selectivity, especially at industrially relevant high current density conditions, is needed to expedite the economic viability of the CO₂RR. For this purpose, bimetallic materials, where copper is combined with a secondary metal, comprise a promising and a highly tunable catalyst for the CO₂RR. Nevertheless, the synergy between copper and the selected secondary metal species, the evolution of the bimetallic structural motifs
