Abstract：The effect of continuous discharge and adsorptive storage-intermittent discharge combined with SBA-15on toluene decomposition was investigated under ambient pressure and temperature. The results showed that adsorptive storage-intermittent discharge method exhibited higher toluene conversion, CO2 selectivity and better carbon balance compared to the former. The evolution of the intermediate products on the catalyst surfaces with time were also analysed by GC-MS in both methods. The results indicated that formaldehyde oxidation was the rate-determining step for toluene decomposition. Then, the activities of four different catalysts, SBA-15, Mn/SBA-15, Ag/SBA-15and AgMn/SBA-15were tested with dsorptive storage-intermittent discharge mode. AgMn/SBA-15catalyst exhibited the highest CO2 selectivity and the best carbon balance among the tested catalysts, which may be due to 2-heptene alcohol oxidation catalyzed by the addition of Ag and Mn.
