This study reports the construction of dinuclear heterovalent metal catalysts via pyridine-based ligands and cuprous iodide clusters, and the investigation of their catalytic activities in the oxidative coupling of benzylamine. By adjusting the ligand geometry, structural tuning from one-dimensional (1D) chains to two-dimensional (2D) cyclic frameworks was achieved to obtain a series of dinuclear heterovalent metal catalysts (DCu-T1 to DCu-T6). Among them, the cyclic DCu-T6 exhibited superior catalytic performance in benzylamine coupling, with a conversion rate of 99%, which significantly surpassed that of the mononuclear control catalyst TPY-Cu (20%). Mechanism studies reveal a synergistic effect between binuclear metal sites of different valence states, which is validated by electron paramagnetic resonance (EPR), in situ infrared (IR) spectroscopy, and theoretical calculations. These results provide a strategy for the construction of high-performance dual-site heterovalent catalysts and clarify the atomic-level catalytic mechanism responsible for their enhanced efficiency.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"53 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145103569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Controlling the morphology of 2D CPs remains challenging. In this study, pseudohalide anions (SeCN^–, SCN^–) were employed as crystal growth modifiers to achieve precise morphological control, leveraging their distinct coordination capacities and steric hindrance effects. Specifically, the large atomic radius and high polarizability of Se in SeCN^– facilitate the lateral growth of CPs, leading to the formation of uniform lamellar structures. Co-CP-Se delivered a specific capacitance of 1483 F g^–1 at 1 A g^–1 and maintained 93.23% of its initial capacitance after 5000 cycles at 10 A g^–1. A hybrid supercapacitor (Co-CP-Se//AC) demonstrated a power density of 750 W kg^–1 at an energy density of 42.14 Wh kg^–1 while maintaining 90.12% capacitance retention after 5000 cycles (10 A g^–1). Mechanistic investigations revealed that partial substitution of −SeCN by OH^– during cycling generated Co(OH)₂, which synergistically contributed to the capacitance together with Co-CP-Se.
