WO3–CeO2 and Pd/WO3–CeO2 as Potential Catalysts for Reforming Applications

Decomposition of 1,2-dichloroethane over CeO2 modified USY zeolite catalysts: Effect of acidity and redox property on the catalytic behavior

“…7. For pure CeO 2 sample, two peaks observed at temperature below 600 • C are ascribed to the reduction of superficial oxygen and the peak detected above 600 • C is assigned to the reduction of bulk oxygen [32]. For CeO 2 -USY, the dispersion of CeO 2 species on USY zeolite results in the small particles of CeO 2 species, which is beneficial for the mobility of oxygen species in comparison with pure CeO 2 .…”

Characterization of WOx/CeO2 catalysts and their reactivity in the isomerization of hexane

“…The catalyst calcined at 973 K exhibited a line at 460 cm −1 assigned to crystalline ceria (E g mode) [37]. The broad band between 700 and 850 cm −1 can be assigned to the presence of amorphous WO 3 oxide, and the two sharper lines in the region 900-950 cm −1 , to W=O t stretching modes of isopolytungstate species [38,39]. The increase of calcination temperature resulted in a much better defined structure as inferred from the sharp lines in the region of oxotungstate species.…”

Catalytic Activity of Y Zeolite Supported CeO2 Catalysts for Deep Oxidation of 1, 2-Dichloroethane (DCE)

“…4, it can be seen that the there are three hydrogen consumption peaks during CeO 2 reduction in the range of 300-700°C. The first two peaks at lower temperature (about 380 and 518°C) are usually ascribed to the reduction of surface oxygen, and the third one at high temperature ([700°C) is ascribed to the reduction of bulk oxygen of the CeO 2 structure [43]. No hydrogen consumption peaks are observed on USY, HY, and SSY supports (It is not lined out in Fig.…”
