  • Coating the silica material with zirconia via dry-impregnation to enhance adsorptive capability.
  • Testing the material's adsorption of N'-nitrosonornicotine (NNN) and N-nitrosopyrrolidine (NPYR) in solution and gas streams.

    • Main Results:

    • Successful synthesis of a block-like, 3D net-linked SBA-15 material.
    • Demonstrated high activity in adsorbing both bulky (NNN) and volatile (NPYR) nitrosamines.
    • Efficient reduction of nitrosamines and total particles in mainstream cigarette smoke when used as a filter additive.

    Conclusions:

    • The novel 3D net-linked SBA-15 material is a versatile functional adsorbent.
    • This material shows significant potential for reducing carcinogenic nitrosamines in tobacco smoke.
    • The material offers a promising solution for environmental and public health protection against tobacco-related pollutants.
