High Catalytic Performance of Bimetallic Sites Catalyst MOF@MT‐COF‐Cu for Benzimidazole and Benzothiazole Derivatives

ABSTRACT An efficient catalytic system was developed to rapidly synthesize benzimidazole and benzothiazole derivatives under green and mild conditions using MOF@MT‐COF‐Cu, which contains Zr‐Cu bimetallic catalytic sites as heterogeneous catalysts. The catalysts were characterized by powder X‐ray diffractometer (PXRD), field emission scanning electron microscope (FE‐SEM), energy‐dispersive X‐ray analysis (EDS), transmission electron microscope (TEM), Fourier transform infrared spectroscopy (FT‐IR), X‐ray photoelectron spectroscopy (XPS), N 2 adsorption–desorption, thermogravimetric analysis (TGA), and inductively coupled plasma optical emission spectroscopy (ICP‐OES). The prepared hybrid material has been demonstrated to be an excellent catalyst because it has Zr and Cu bimetallic catalytic sites and combines the high specific surface area and robust stability of MOF and COF. In addition, the catalyst exhibits several advantages, including high catalytic activity, easy recovery, good repeatability, and excellent stability.
