Abstract :
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 was examined by using various solvents
(methanol, acetone, acetic acid, acetonitryl). The maximum yield
(25%) and selectivity (73%) of the phenol produced were obtained
in the presence of acetic acid. The catalyst can be reused for
several times without any appreciable loss of activity.
