Influence of the substituent on selective photocatalytic oxidation of aromatic compounds in aqueous TiO2 suspensions.
Experimental results are reported showing that the photocatalytic oxidation of aromatic compounds containing an electron-donor group (EDG) gives rise mainly to ortho- and para-monohydroxy derivatives while in the presence of an electron-withdrawing group (EWG) all the monohydroxy derivatives are obtained.
متن کاملFerrate(VI) enhanced photocatalytic oxidation of pollutants in aqueous TiO2 suspensions.
BACKGROUND, AIM AND SCOPE Photocatalytic oxidation using UV irradiation of TiO(2) has been studied extensively and has many potential industrial applications, including the degradation of recalcitrant contaminants in water and wastewater treatment. A limiting factor in the oxidation process is the recombination of conduction band electrons (e(-)(cb)) with electron holes (h(vb)(+)) on the irradi...
متن کاملPhotocatalytic degradation of mecoprop and clopyralid in aqueous suspensions of nanostructured N-doped TiO2.
The work describes a study of the oxidation power of N-doped and undoped anatase TiO(2), as well as TiO(2) Degussa P25 suspensions for photocatalytic degradation of the herbicides RS-2-(4-chloro-o-tolyloxy)propionic acid (mecoprop) and 3,6-dichloro-pyridine-2-carboxylic acid (clopyralid) using visible and UV light. Undoped nanostructured TiO(2) powder in the form of anatase was prepared by a so...
متن کاملPhotocatalytic degradation of 4-nitrophenol in aqueous TiO2 suspensions: Theoretical prediction of the intermediates
The kinetics of the photocatalytic degradation of 4-nitrophenol (4-NP) in the presence of TiO2 has been investigated experimentally and theoretically. The effects of the catalyst loading, the initial concentration of 4-NP, H2O2 and the added Cu2+ ions on the degradation rate have been examined. A pseudo-first order kinetic model has been used to describe the results. A linear dependence of the ...
متن کاملPHOTOCATALYTIC DEGRADATION OF THE ORGANOPHOSPHORUS PESTICIDE FENTHION IN AQUEOUS SUSPENSIONS OF TiO2 UNDER UV IRRADIATION
In present study the photocatalytic degradation of the organophosphorus pesticide fenthion, under UV irradiation in the presence of titanium dioxide (TiO2) photocatalyst, in aqueous suspensions has been investigated and compared with the photodegradation by hydrogen peroxide (H2O2) solution as an oxidant agent. The experiments were carried out in a 250mL pyrex UV laboratory-constructed photorea...
