Synthesis, Characterization and Catalytic Activity of Molybdenum Oxide Nanoparticles by Albumen, Assisting Microwave Process for Dehydrogenation of 1,4-Dihydropyridines

Abstract

Molybdenum oxide (MoO3) nanoparticles were synthesized via microwave method with albumen as a bio template followed by calcination at 400 °C. The obtained product was characterized by X-ray diffraction (XRD), scanning electron microscopy, transmission electron microscopy, FT-IR and UV–Vis techniques. The XRD results showed that whereas the prepared sample was amorphous up to 300 °C, a crystalline phase of orthorhombic symmetry with amourphous phase was obtained at 400 °C. The thermogravimetric analysis data showed the thermal stability of molybdenum oxide. The MoO3 nanoparticles was found to catalyze aromatization of 1,4-dihydropyridines efficiently with 100 % conversion and selectivity.
