Abstract

Abstract: Multi-metallic MOFs, characterized by multiple metal active centers, exhibit promising potential in the catalytic activation of molecular oxygen owing to the synergistic electronic effects between different metal species. In this work, a BiFeCo-MOF material with Bi3+, Fe3+ and Co2+ as multimetal centers was successfully constructed via a static solvothermal method and applied to the efficient aerobic oxidative dehydrogenation of terpinene. The as-prepared Bi2Fe2Co4-MOF-BDC-150-24 catalyst was systematically characterized by XRD, IR, SEM, XPS, and NH3-TPD,confirming its stable structure and the presence of multimetal electronic synergy. Under near-ambient conditions, the catalyst enabled the selective conversion of the C-C single bond in terpinene to a C=C double bond without any external additives, achieving a conversion of 96.1%. Moreover, the material exhibited good substrate versatility, providing conversions of 97.2% for γ-terpinene and 93.9% for phellandrene. Recycling tests showed that the catalyst maintained high activity after five consecutive runs, demonstrating excellent cycling stability and promising application potential.
