Effect of support on V2O5 catalytic activity in chlorobenzene oxidation

Deactivation mechanism of arsenic and resistance effect of SO42− on commercial catalysts for selective catalytic reduction of NO with NH3

“…And all the catalysts produced Raman peaks at 145, 197, 395, 515, and 637 cm -1 in Figure 2, which correspond to the anatase phase of TiO 2 . [21][22][23] Both results indicate that arsenic at a certain amount (As 2 O 3 3.37% on the poisoned #1 and As 2 O 3 2.48% on the poisoned #2) does not bring changes to the crystalline phase of catalysts. Based on the N 2 O concentration results in Figure 3, it is observed that N 2 O formation is almost the same below 300 °C among three samples and begins to differentiate at a higher temperature, which coincides with the tendency of activities.…”

Recent Advances in the Catalytic Oxidation of Volatile Organic Compounds: A Review Based on Pollutant Sorts and Sources

“…An increase in the LAS also improves the spreading of the VOx phase on the surface of the catalyst. 728,915 Huang et al 916 revealed that the addition of MoO3 to V2O5/TiO2 improved the catalyst redox properties and enhanced the CB oxidation activity at low temperatures. However, the formation of low amounts of polychlorinated compounds over V2O5-WO3/TiO2 and V2O5-MoO3/TiO2 was reported by Busca and co-workers.…”

Performance of platinum and gold catalysts supported on ceria–zirconia mixed oxide in the oxidation of chlorobenzene

“…Doping of V 2 O 5 -TiO 2 catalysts with ceria increased their activity in chlorobenzene oxidation, which was related to the redox properties of ceria [8]. Similarly, the addition of ceria to Pt/Al 2 O 3 and Pd/Al 2 O 3 catalysts increased their performance in the oxidation of perchloroethylene and such catalysts were superior to that based on Rh and V 2 O 5 [9].…”
