Surface potential study of adsorbed oxygen species on aerogel catalyst in toluene oxidation
نویسندگان
چکیده
The surface potential, measured by the Kelvin method, allows one to determine the dominant oxygen species adsorbed on the surface of a aerogel during catalysis of toluene oxidation. Between 523 and 623 K, reaction takes place by a redox 2323 mechanism, the rate-determining step being the dissociation of oxygen during the reoxidation of the reduced centre. These results are in full agreement with already published kinetic and spectroscopic studies.

Deactivation kinetics of V/Ti-oxide in toluene partial oxidation
Deactivation kinetics of a V/Ti-oxide catalyst was studied in partial oxidation of toluene to benzaldehyde (BA) and benzoic acid (BAc) at 523–573 K. The catalyst consisted of 0.37 monolayer of VOx species and after oxidative pre-treatment contained isolated monomeric and polymeric metavanadate-like vanadia species under dehydrated conditions as was shown by FT Raman spectroscopy. Under the reac...
متن کاملKinetic Studies of the Catalytic Oxidation of Toluene to Benzoic Acid in the Liquid Phase
The catalytic oxidation of toluene to benzoic acid in the liquid phase has been studied in an un-stirred tank reactor. Low concentration of acetic acid was added in order to increase the solubility of the catalyst in toluene. The dependence of the rate of reaction on the concentration of toluene catalyst and oxygen pressure was studied. It has been suggested that liquid phase oxidation of t...
متن کاملTransient kinetics of toluene partial oxidation over V/Ti oxide catalysts
Transient kinetics in the toluene oxidation over V/Ti oxide catalysts prepared by grafting and impregnation have been compared. V4+ cations are supposed to be the sites for the formation of electrophilic oxygen species participating in deep oxidation. Another oxygen species (probably nucleophilic) present on the oxidised catalyst surface are responsible for benzaldehyde formation. Selectivity o...
متن کاملEffect of potassium doping on the structural and catalytic properties of V/Ti-oxide in selective toluene oxidation
Small addition of potassium to V/Ti-oxide catalyst (K:V=0.19), consisting of 3.7 monolayer VOx , increased activity and selectivity in partial oxidation of toluene. In order to elucidate the nature of vanadia species formed on the surface of V/Ti-oxide upon potassium doping, the catalysts were studied by transient kinetics method. The transient product responses during toluene oxidation by the ...
متن کاملVanadia/titania catalysts for gas phase partial toluene oxidation Spectroscopic characterisation and transient kinetics study
Formation of vanadia species during the calcination of ball milled mixture of V2O5 with TiO2 was studied by Raman spectroscopy in situ and at ambient conditions. It is found that calcination in air leads to fast (1–3 h) spreading of vanadia over TiO2 followed by a slower process leading to the formation of a monolayer vanadia. The calcinated catalyst showed higher activity during toluene oxidat...
