The main objective of this research is to develop efficient and environmentally benign heterogeneous catalysts for synthesis of 2-arylbenzimidazole and 2-arylbenzothiazoles derivatives by MnO₂/MOF-199. For this purpose, a heterogeneous MnO₂/MOF-199 catalyst was prepared by the solvothermal method, and the prepared catalyst was characterised by various techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), BET, IR, thermogravimetric–differential thermogravimetric (TG-DTG), and temperature-programmed desorption with ammonia (NH₃-TPD) analysis. The solid catalyst, with a MnO₂/MOF-199 loading of 9 %, demonstrated a high catalytic activity in the synthesis of 1,2-arylbenzimidazole and 1,2-arylbenzothiazole derivatives and the catalyst could be reused for at least 5 cycles under mild conditions.

这项研究的主要目的是开发有效和环境友好的非均相催化剂，用于通过MnO ₂ / MOF-199合成2-芳基苯并咪唑和2-芳基苯并噻唑衍生物。为此，通过溶剂热法制备了MnO ₂ / MOF-199非均相催化剂，并通过X射线衍射（XRD），扫描电子显微镜（SEM），透射电子显微镜（ TEM），BET，IR，热重-差热重（TG-DTG）和程序升温的氨解吸（NH ₃ -TPD）分析。具有MnO ₂的固体催化剂/ MOF-199负载量为9％，表明在合成1,2-芳基苯并咪唑和1,2-芳基苯并噻唑衍生物中具有很高的催化活性，该催化剂在温和条件下可重复使用至少5个循环。
