Abstract:		"To achieve efficient degradation of toluene, a series of Cu(1-y)Mn(2)Ce(y)O(x)/sepiolite catalysts (y?ª+=?ª+0.1, 0.2, and 0.3) with different Cu(1-y)Mn(2)Ce(y)O(x) loadings (10%, 20%, and 30%) were prepared via the co-precipitation method. The structure-activity and surficial elemental species of Cu(1-y)Mn(2)Ce(y)O(x)/sepiolite were characterized by XRD, TEM, SEM, BET, ICP-MS and XPS. The catalytic activity of the catalysts was tested in the oxidation reaction of toluene, results showed that 20%Cu(0.8)Mn(2)Ce(0.2)O(x)/sepiolite remains able to remove toluene completely with high efficiency at a temperature of 289?ª+ degrees C. Two kinetic models have been selected and tested to describe the oxidation of toluene, the Mars-van krevele (MVK) model provided a good fit (R(2)?ª+>/=?ª+0.99). And the optimal relation of the surface oxidation activation energy (26.074?ª+kJ?ª+mol(-1)) and surface reduction activation energy (23.591?ª+kJ?ª+mol(-1)) were calculated"
