Design, Synthesis and Use of Transition Metal Oxide Spinels (Cobalt and Iron) as Catalysts in Organic Reactions
, M.Sc. Thesis Sharif University of Technology ; Matloubi Moghadam, Firouz (Supervisor)
Abstract
Bread scraps with transition metals oxides spinels have been utilized to synthesize¬ magnetic nanocatalyst. The heterogeneous catalyst was characterized using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET), thermogravimetric analysis (TGA) and transmission electron microscopy (TEM). The reaction was performed for tandem Knoevenagel-Micheal reaction in the presence of synthesized nanocatalyst as a heterogeneous, environmentally benign, cost-effective catalyst with high catalytic activity using EtOH as a green solvent. The magnetic nanocatalyst was applied to synthesize tetraketones and pyranopyrazoles...
