Supported metal oxides for catalytic combustion of CO and VOCs emissions: preparation of titania overlayers on a macroporous support

Pd-CeO2 and Pd-La2O3/alumina-supported catalysts: their effect on the catalytic combustion of methane

“…With regard to the support, the use of partially reduced supports such as TiO 2 and ZrO 2 may produce solids with higher catalytic activity. The enhancement of activity of metal-supported catalysts may also be obtained with the addition of La 2 O 3 , CeO 2 and ZrO 2 , which can improve the stability and the catalytic activity of the support [3,4]. The ability of CeO 2 -based promoters to act as an oxygen buffer through the oxygen storage capacity provides a way to increase the efficiency of three-way catalysts by enlarging the air-to-fuel operating window [5,6].…”

Catalytic oxidation of industrial organic solvent vapors

“…[16−19] According to literature [17−19] CuO/γ -Al 2 O 3 seems to have very good results in toluene oxidation. Larson et al have used various metals (Cu and Co) on different support materials (SiO 2 , γ -Al 2 O 3 and TiO 2 ) for the catalytic oxidation of toluene and CO. [18] This research has concluded that titania and alumina greatly enhance the activity of CuO. Kim the most active.…”

“…They possess high activities but are expensive. However, there is a potential for supported metal oxide catalysts, since they are cheaper, less sensitive to certain catalyst poison but less active [2][3][4] , compared with the noble metals. Furthermore, it is well known that supports play an important role in catalytic activity enhancement 5 .…”
