Significant Promotion of Morphology in Fabricating Efficient Environment Protector

A new strategy of morphology control was applied for mesoporous silica SBA-15 to fabricate efficient envi- ronment protector, and the micro- and macro-morphology of SBA-15 were simultaneously controlled in weak acidic condition by using citric acid. Through simply tuning the synthetic temperature, monolithic SBA-15 materi- als with tunable macroporous structure was fabricated by using mild shearing force field in the citric acid route. Owning to the strong promotion of special morphology, the SBA-15 monolith can efficiently eliminate the phenol from environmental tobacco smoke (ETS), and the reduction ratio is twice higher than that by tetraethylenepen- tamine (TEPA) modified powder-like SBA-15. These results indicated that morphology of mesoporous materials played a dominant role in environmental purification.
