    Effect of SBA-15 morphology in the composition of the mainstream tobacco smoke

    MARTÍNEZ-CASTELLANOS I.; MARCILLA A.; BELTRÁN M.I.; BERENGUER D.; BLASCO I.; JUAREZ N.; ASENSIO J.; CALABUIG E.
    University of Alicante, Alicante, Spain
    Mesoporous silica materials, such as SBA-15, are attracting increasing interest in the last years. Our research group has focused in their capability for reducing the toxic compounds generated in the smoking process when mixed with tobacco. By tuning the ...

    Influence of the time of synthesis of SBA-15 on its effect as a catalyst reducing toxicant concentration in tobacco smoke

    JUÁREZ-SERRANO N.; MARCILLA A.; BELTRÁN M.I.
    University of Alicante, San Vicente del Raspeig, Spain
    In recent years, SBA-15 has been suggested as an additive for reduction of toxic compounds in tobacco smoke. The structure of this type of materials is strongly dependent on the synthesis conditions. The objective of the present work is to analyze the ...
