Total oxidation of model volatile organic compounds over some commercial catalysts

Effect of preparation procedure on the formation of nanostructured ceria–zirconia mixed oxide catalysts for ethyl acetate oxidation: Homogeneous precipitation with urea vs template-assisted hydrothermal synthesis

“…The increasing detrimental environment and health effect provides not only a necessity to strict regulation of VOCs emissions but also development of efficient, low cost and environmentally friendly therein]. Ceria doping with zirconia improves essentially its thermal stability and catalytic efficiency [3,4,9,[13][14][15], which provokes its application in the three way catalyst formulations, solid oxides fuel cells and water splitting devices. Many studies emphasize the relationship between the catalytic activity and defect structure of these oxides [8,[16][17][18][19][20][21][22][23][24][25][26][27].…”

Total oxidation of ethanol over Au/Ce0.5Zr0.5O2 cordierite monolithic catalysts

“…It was demonstrated earlier that the catalytic performance in alcohol oxidation can be influenced by noble metal loading and/or particle size [33][34][35]. Minicò et al [36] concluded that the high activity of Au/Fe 2 O 3 catalyst in ethanol oxidation was related to the capacity of highly dispersed gold to weaken the Fe-O bond thus increasing the mobility of the lattice oxygen which is involved in ethanol oxidation probably through a Mars-van Krevelen reaction mechanism.…”

Catalytic combustion of toluene over copper oxide deposited on two types of yttria-stabilized zirconia

“…On the other hand, such catalysts can be easily poisoned by contaminants and are expensive, and therefore transition metal oxides have been often examined as components of catalysts for the purification of VOCs containing gases [1]. Among them, supported copper and manganese oxides turned out to be the most active materials [4][5][6][7]. It was postulated [8] that the adsorption of the toluene molecule is the initial step of toluene oxidation over a CuO-CeO 2 /␥-Al 2 O 3 catalyst.…”
