摘要： 多金属MOFs材料具备多种金属活性中心，不同金属间的电子协同效应使其在催化活化分子氧领域表现出宽广的研究前景。本文通过静态溶剂热法成功构建了以Bi3+、Fe3+和Co2+为多金属中心的BiFeCo-MOFs材料，并应用于松油烯的高效空气氧化脱氢反应。所制备的Bi2Fe2Co4-MOF-BDC-150-24催化剂经XRD、IR、SEM、XPS和NH3-TPD等系统表征，证实其结构稳定且存在多金属电子协同效应。在近室温条件下，该催化剂可在无外加助剂条件下实现松油烯中C?C单键向C=C双键的选择性转化，转化率达96.1%。此外，该材料表现出良好的底物普适性，对γ-松油烯和水芹烯的转化率分别为97.2%和93.9%。循环实验表明，催化剂在连续使用5次后仍保持高活性，具备优异的循环稳定性与潜在应用价值。

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.
