Preparation and characterization of 20 wt.% V2O5-TiO2 catalyst oxidation of cyclohexane
The 20 wt.% V2O5-TiO2 catalyst was prepared by the sol-gel route and calcined at 300 degrees C. XRD, TEM, EDX and FT-IR analysis showed that the material presents a crystalline structure with the presence of both TiO2 rutile and anatase varieties. BET analysis showed a low oxide surface area (27 m(2)/g). Cyclohexane oxidation with hydrogen peroxide in presence of the catalyst showed a low conversion. The use of acetic acid as solvent and acetone as initiator presented an approximate 8% conversion into cyclohexanol, with 76% selectivity. (c) 2006 Elsevier B.V. All rights reserved.
