| Abstract: | Microporous-mesoporous composite material (MMM）was prepared from TEOS, with CTAB and TPABr used as templates, through simultaneous crystallization.The as-made MMM was characterized by N2 adsorption/desorption, XRD and FT-IR.The results showed that the MMM has composite pore structure combining both micropores and mesopores, and the pore sizes are mainly located at 0.54 nm, 1.4 nm, 2.8 nm and 3.7 nm.The specific surface area of the MMM was 361.3 m2·g-1 with a pore volume of 0.347 cm3·g-1.In addition, the property of the MMM to remove harmful components in cigarette mainstream smoke has been investigated.Comparing with the reference cigarette (without MMM in filter), the deliveries of harmful components in mainstream smoke of experimental cigarette (with MMM in filter, 5 mg·cig-1）were reduced in varying degrees, in which the deliveries of NNK, B［a］P and phenol were reduced 24.34%, 26.25% and 43.40%, respectively, showing that the MMM was a promising filter additive. |
