The relationship between the size of Cu nanoclusters (CuNCs) derived from single‐atom catalysts and the performance of the CO reduction reaction was systematically examined. Larger CuNCs, characterized by a higher proportion of terrace surfaces that facilitate CO dimerization, demonstrated enhanced C2+ selectivity and formation rates.
