文摘Six transition metal oxides were added in ceria-modified titania using a sol-gel method for catalytic oxidation of toluene.An MnOx based catalyst was found to be the most active one,with which toluene could be decomposed completely at 200 oC.The greatest Mn/Ti and molar ratio of the mobile oxygen to the total oxygen concentration,together with a large surface area and a low reduction peak-starting temperature,would result in its best activity in toluene oxidation.
