It is a challenging scientific problem to establish a highly efficient and stable catalytic system with a clear structure-activity relationship through precise chemical design and directional synthesis.1 Especially for the electrocatalysis systems, the synthesize of catalysts with a long-term stable active site as a difficult issue as it usually reacts in a relatively harsh chemical environment and the electrocatalytic process is accompanied by redox reactions. 2 Therefore, it is particularly important to synthesize a catalyst with good stability and catalytic activity. Over the past decade, electrocatalytic systems based on metal compounds, metal and alloy catalysts, clusters, and non-metallic materials have made continuous progress.3 But for molecular clusters that has good advances in the fields of luminescence, magnetism and catalysis,4 it is full of challenges and opportunities in this research area, especially for the electrocatalytic oxygen evolution reaction (OER) and urea oxidation reaction (UOR) catalytic environment of strong alkaline conditions. So far, there are no reports about coordination molecular clusters applied to both OER and UOR reactions (Table S3-4).
