48Synthesis and characterization of V2O5 TiO2 nanostructure for selective oxidation of benzene to phenol in mild condition Parisa Rezaee p rezaee@ch iut ac ir Department of Chemistry Isfahan University of Technology Isfahan 84156 8311 Iran Supervisor Prof M Ghiaci mghiaci@cc iut ac irDegree M Sc Language PersianAbstractBenzene is known as the cancer reason in recent years hence too much effort are done towithdraw it from environment by using it at laboratories and industrial sections The mostimportant application of it is synthesis of phenol and its derivativies which almost alwaysare done by oxidation of benzene The main procedure in order to synthesis phenol is Cumene process This process is beneficial due to usage of low cost reagents however it also has some disadvantages for instance high energy consumption side product likeacetone and also high pressure and temperature condition As the matter effect catalyticoxidation of benzene to phenol achieved so much attention in recent years According torecent reasons so much effort is done to the perpuse of acquiring phenol with high yieldand selectivity by desigining a heterogenous nanocatalyst base on titanium dioxide as asupport in this work By using vanadium pentoxide as catalyst on a support of titaniumdioxide high promotion of reaction yield was achieved Afterall the prepeared catalyst wasdetermined by BET FESEM EDX Mapping XRD TEM XPS and ICP Finally theprepeared nanaocatalyst was used for benzene oxidation and the optimum condition forthe reaction was gained All in all optimum condition for temperature time oxidant andcatalyst amount parallel to yield and selectivity of phenol was achieved Keywords Benzene Phenol Hydrogen peroxide vanadium pentoxide titanium dioxide oxidation
