A new strategy of morphology control was applied for mesoporous silica SBA‐15 to fabricate efficient environment 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 materials 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 tetraethylenepentamine (TEPA) modified powder‐like SBA‐15. These results indicated that morphology of mesoporous materials played a dominant role in environmental purification.
