Title
Total oxidation of toluene and oxygen storage capacity of zirconia-sol modified ceria zirconia
Abstract

This paper provides novel knowledge about the positive effect of ZrO2 sol addition on CeO2–ZrO2 mixed oxides (CZ) catalyst for the total oxidation activity of toluene. The composite catalysts of CZ powders with 6–23 wt.% ZrO2 prefer to make better microstructure for catalytic oxidation activity than CZ itself. Possible mechanism on improvement of conversion of toluene to CO2 was proposed due to the modification of surface basicity by ZrO2 addition. It was discussed that the stronger adsorption site of CO2 on dispersed ZrO2 would accelerate to remove reactant CO2 from active CZ surface onto dispersed ZrO2 in the oxidation reaction of toluene.
