摘要
Novel thiol-functionalized mesoporous silica nanorods （MSNRs） were synthesized through a base co-condensation method, in which two organoalkoxysilanes, tetraethoxylsilane （TEOS） and bis[3-（triethoxysilyl）propyl]tetrasulfide （TESPT）, were used as silica precursors simultaneously. TESPT was firstly used for both morphology control and inner surface functionalization of mesoporous silica hybrid materials. The micro- structures as well as porous character of the MSNRs were characterized by means of SEM, XRD, TEM and N2 sorption measurements. Infrared spectrum analysis and heavy metal ions （Ag＋ and Cd2＋） adsorption measurements were carried out to confirm the functionalized framework of MSNRs.
