Description

V2O5/SiO2 nanoparticles was prepared via an one-pot sol gel method from vanadyl- acetylacetonate and tetraethyl orthosilicate in refluxing MeOH, followed by calcination at 700 °C for 2 hours. The resultant nanoparticles was characterized by means of scanning electron microscopy, transmission electron microscopy, X-ray diffraction, TGA and FTIR techniques. Rapid and efficient aromatization of 1,4-dihydropyridines catalyzed by V2O5/SiO2 nanoparticles is described in this presentation.
