In the field of sustainable energy conversion and storage technologies, copper-based complexes have become a research hotspot due to their efficient stable catalytic performance. The development bifunctional catalysts that can simplify steps, enhance efficiency, reduce catalyst usage has an important area. this study, we successfully synthesized two copper with different geometries utilizing di(2-pyridyl) ketone as ligand, [CuII2L2Cl2]·0.5H2O (1) [Cu4IIL4(OCH3)2](NO3)2 (2) (L = deprotonated methoxy-di-pyridin-2-yl-methanol), which serve homogeneous electrocatalysts for water oxidation CO2 reduction simultaneously. turnover frequency (TOF) 1 2 electrocatalytic are 7.23 s−1 0.31 under almost neutral condition (pH 8.22), respectively. Meanwhile, TOF CO 4.27 8.9 s−1, addition, both remain essentially unchanged during processes, demonstrating good stability. Structural analysis reveals distinct efficiencies originate from geometric configurations: binuclear structure complex facilitates proton-coupled electron transfer oxidation, whereas tetranuclear architecture enhances activation. Complexes represent first molecular capable catalyzing reduction. findings in work open up new avenues advancement artificial photosynthesis simulation
