Abstract In this study, different concentration and different types of acid solution was used for the cordierite pretreatment. The changes of basic performance before and after the pretreatment and the performance of the catalytic degradation of toluene were examined. The weightlessness rate, the rate of water absorption and upload rate of cordierite were also tested. XRF, BET, SEM characterization methods were used for the assessment of cordierite. The best cordierite carrier in our experiment could be obtained by heating with 20%HCl for 3h. The water absorption rate increased by more than 48.0% compared with that before treatment, the upload rate could reach 14.5%. A moderate positive correlation between water absorption and upload rate was assumed by the pearson test. The characterization results showed that the specific surface area could increase with more than 10times through acid treatment. The T₁₀ and T₉₀ of catalytic degradation of toluene were 143℃ and 200℃, respectively.
