Comparative study of the oxidative decomposition of trichloroethylene over H-type zeolites under dry and humid conditions

Fabrication of mesoporous Co3O4 oxides by acid treatment and their catalytic performances for toluene oxidation

“…For the catalytic reaction of VOCs oxidation, the adsorption of VOCs molecules on the catalyst surface could also be of great importance. It has been shown that hydrocarbon oxidation could be initiated by the adsorption of hydrocarbons on the surface acidic sites of a catalyst by proton transfer [57,58], while the concentration and strength of surface acidic sites could influence the strength or extent of adsorption/oxidation of hydrocarbon molecules. Thus, the surface acidity of a catalyst may be another factor in VOCs oxidation.…”

Catalytic abatement of trichloroethylene over Mo and/or W-based bronzes

“…On the other hand, chromium oxides are active [27], but their application is restricted to low operation temperatures because the formation of volatile and very toxic chromium oxychloride can occur. In the last years, new catalysts based in zeolites have been proposed as active catalysts for this reaction obtaining interesting results [28][29][30][31][32]. Nevertheless it is still necessary to find more active and stable materials.…”

The oxidation of trichloroethylene over different mixed oxides derived from hydrotalcites

“…Metal oxides [5][6][7][8] or supported noble metals [9,12] have been the most common catalysts used in this reaction, but they have some drawbacks as the poisoning by chlorine [4] and the formation of chlorinated by-products that can be very toxic [7,13]. Recently, other materials have been used for the catalytic oxidation of CVOCs as zeolites [12,14] and bronzes [15], but it is still necessary to find more active and stable…”
