摘要: Abstract This paper reported the synthesis, characterization, adsorption and catalysis of new morphology-assisted functional SBA-15, 3D net-linked mesoporous silica monolith, its actual function in selective reducing tobacco specific nitrosamines (TSNA) level smoke, order to explore route elevating efficiency environment adsorbents/catalysts through their morphology controlling. It is feasible control hydrolization condensation source then piloting formation secondary arrangement primary particles, finally forming monolith with morphology. The resulting sample not only had shape but also possessed a considerable mechanical intensity hence it could be directly sieved for use without molding. With assistant morphology, this intercept particles μm sizes selectively capture TSNA adhered on particle, providing material protection. Through dry-impregnation successful modify zirconia guest damage dramatically increasing activity composite instantaneous volatile nitrosamine such as N -nitrosopyrrolidine (NPYR) temperature programmed surface reaction (TPSR) ′-nitrosonornicotine (NNN), offering powerful environmental catalyst degrade carcinogenic pollutants.
