Fine constructing the chemical environment of central metal is vital in developing efficient single-atom catalysts (SACs). Herein, atomically dispersed Cu on N-doped carbon modulated by introducing CuP moiety to CuNC SAC. Through fine-tuning with another heteroatom P, SAC shows superior performance ethylene oxychlorination. The site activity Cu-NPC four times higher than P-free Cu-NC catalyst and 25 Ce-promoted CuCl2 /Al2 O3 long-term test (>200 h). selectivity dichloride can be splendidly kept at ≈99%. Combined experimental simulation studies provide a theoretical framework for coordination Cu, N, P complex active center its role effectively catalyzing It integrates oxidation chlorination reactions catalytic unrivaled ability corrosive-HCl resistance. concept fine anticipated inspiration rational design expand applications carbon-based SACs heterogeneous catalysis.
