Photocatalytic destruction of gaseous diethyl sulfide over TiO2

Adsorption and degradation of model volatile organic compounds by a combined titania–montmorillonite–silica photocatalyst

“…Toluene is a toxic compound listed in Title III of the 1990 Clean Air Act Amendment proposed by the Environmental Protection Agency of USA; ethyl acetate (EA) is a kind of irritative and explosive compound with fragrant odor [2], which is harmful to respiratory systems of mankind [26], while ethanethiol (EtSH) is high toxic pollutants with strong unpleasant odor and very low perceptibility threshold [27]. Three VOCs with different polarities as single and multinary VOCs were chosen as the model pollutants in a fluidized bed photocatalytic reactor to evaluate the adsorptive performance and photocatalytic activity of the prepared photocatalysts.…”

Aproximaciones biológicas y fisicoquímicas en el tratamiento de contaminantes: un resumen del aporte de la Universidad de los Andes1

“…Se ha comprobado que la degradación fotocatalítica es efectiva y viable para la destrucción del contaminante con el catalizador TiO 2 . Los procesos de fotocatálisis heterogénea permiten la transformación de contaminantes sobre TiO 2 bajo la radiación de luz UV [36]. Teniendo un proceso con luz UV y catalizador simultáneamente, se han alcanzando conversiones de casi el 100% [36].…”

Sulfated TiO2 Decontaminate 2-CEES and DMMP in Vapor Phase

“…Photocatalysis approach, as a new developing and advanced oxidation technology, has been widely applied to the environmental purification [2]. Depended on considerable investigations, researchers have found that photocatalysis method is also effective to decontaminate CWAs and simulants [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Vorontsov et al [5][6][7] investigated the decontamination of Mustard gas simulant 2-CEES over different TiO 2 , and found the main products in the gas phase were CH 3 CHO, CH 3 COOH, C 2 H 4 , CO 2 , H 2 O, HCl, and the surface products were CH 3 COOH, disulfide, sulfoxide (trace), sulfone, SO 4 2-, etc.…”
