Özet

Immobilization of a molybdenum-glycine Schiff base complex onto the supercages of zeolite Y was achieved through the flexible ligand method. The prepared material was characterized by different physicochemical techniques. FT-IR spectroscopy confirmed the immobilization of the complex onto the nanocages of zeolite Y. X-ray diffraction analysis revealed that textural properties of zeolite Y support were preserved during the immobilization process. Nitrogen adsorption-desorption analysis demonstrated the decrease in surface area of the prepared material in comparison with parent zeolite Y. Inductively coupled plasma optical emission spectroscopy showed the presence of 0.75 mmol g(-1) molybdenum in the final material. The obtained material exhibited high catalytic activity, stability, and recyclability in the epoxidation of olefins with tert-butylhydroperoxide as oxidant.
