Abstract:A series of thiol functionalized mesoporous materials(SBA-SH-x) with different thiol ratio[x=n(MPTES)/n(TEOS+MPTES)] were prepared by copolymerization of hydrolyzed TEOS and MPTES in acid condition, using tri-block non-ionic surfactant P123 as template. The structures and properties were characterized by FT-IR, elemental analysis, SEM, TEM, small angle X-ray and N2 adsorptiondesorption. The results showed that x<10%, SBA-SH-x were hexagonal p6mm mesophase; 10%<x<15%, SBA-SH-x were cubic Ia3d mesophase; x>20%, SBA-SH-x were in disorder structure. Further increase of thiol contents resulted in slatted or non-mesoporous materials. The results of Hg2+ adsorption in water indicated that SBA-SH-10 and SBA-SH-15 exhibited good adsorption properties.
