Continuous discharge and adsorptive storage-discharge combined with γ-Al2O3, Ag/γ-Al2O3, NiO/γ-Al2O3 for toluene adsorption and decomposition were investigated by in-situ infrared spectrum technology to study adsorption species on catalyst surface and the role of the addition of catalyst during the toluene degradation. The results showed that adsorptive storage-discharge method exhibited higher toluene degradation and less intermediate products, and the amine wasn't detected. The majority factor was that adsorptive storage-discharge method contributed to the catalyst to enhance the utilization efficiency of the active species generated in the plasma which made intermediates on the catalyst surface rapid stripping and transformation. The results also indicated that the addition of Ag, NiO could reduce the formation of intermediate products, and NiO/γ-Al2O3 played a better role in toluene degradation. © 2015, Chinese Society for Environmental Sciences.
