Vapor-Phase Ammoxidation of ο-Xylene over a Vanadium Catalyst.

Direct oxidation of benzene to phenol in liquid phase by H2O2 over vanadium catalyst supported on highly ordered nanoporous silica

Vanadium supported on highly ordered nanoporous silica (VOx-LUS-1) was synthesized and characterized by XRD, Nitrogen adsorption‑desorption isotherms and UV-visible spectrophotometer. Direct oxidation of benzene to phenol in liquid phase by H2O2 peroxide were examined by using various solvents (methanol, acetone, acetic acid, acetonitryl). The maximum yield (25%) and selectivity (73%) of the ph...

Influence of Vanadium Location in Titania Supported Vanadomolybdophosphoric Acid Catalysts and Its Effect on the Oxidation and Ammoxidation Functionalities

Titania supported vanadomolybdophosphoric acid (VMPA) catalysts with vanadium in different positions, incorporated into the molybdophosphoric acid structure by substituting for molybdenum and cation exchanged on the molybdophosphoric acid surface, were synthesized. The catalysts were characterized by XRD, FT-IR, Raman spectroscopy, TPR, XPS, and ESR techniques. The FT-IR and Raman spectral anal...
