To achieve efficient degradation of toluene, a series of Cu 1-y Mn 2 Ce y O x /sepiolite catalysts (y = 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 °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  ≥ 0.99). And the optimal relation of the surface oxidation activation energy (26.074 kJ mol -1 ) and surface reduction activation energy (23.591 kJ mol -1 ) were calculated., (Copyright © 2018 Elsevier B.V.
