The catalytic oxidation of toluene over Ag/SBA-15 synthesized under different pretreatment condi-tions, including O₂ at 500℃ (denoted O500), H₂ at 500℃ (H500), and O₂ at 500℃ followed by H₂ at 300℃ (O500-H300) was studied. The pretreated samples were investigated by N₂ physisorption, X-ray diffraction, and ultraviolet-visible diffuse reflectance. The pretreatment atmosphere greatly influences the status of the Ag and O species, which in turn significantly impacts the adsorption and catalytic removal of toluene. Ag₂O and amorphous Ag particles, as well as a large amount of subsur-face oxygen species, are formed on O500, and the subsurface oxygen enhances the interaction be-tween Ag species and toluene, so O500 shows good activity at higher temperature. However, its activity at lower temperature is not as high as expected, with a reduced presence of Ag₂O and lower adsorption capacity for toluene. H₂ pretreatment at 500℃ is conducive to the formation of large Ag particles and yields the largest adsorption capacity for toluene, so H500 exhibits the best activity at lower temperatures; however, because of poor interaction between Ag and toluene, its activity at higher temperature is modest. The O500-H300 sample exhibits excellent catalytic activity during the whole reaction process, which can be attributed to the small and highly dispersed Ag nanoparti-cles as well as the existence of subsurface oxygen.
