چکیده    V2o5/sio2 nanoparticles was prepared via an one-pot sol gel method from vanadyl- acetylacetonate and tetraethylorthosilicate in refluxing meoh, followed by calcination at 700 °c for 2 hours. the resultant nanoparticles was characterized by means of scanning electron microscopy (sem), transmission electron microscopy (tem), x-ray diffraction (xrd), tga and ftir techniques. rapid and efficient aromatization of 1,4-dihydropyridines (dhps) catalyzed by v2o5/sio2 nanoparticles is described in this presentation.
