dc.description.abstract | Mesoporous silica (MS) with large pores and thiol functionalized mesoporous silica (TFMS) were synthesized. Si-29 MAS NMR confirmed the functionalization of MPTMS on the surface of mesoporous silica. Silver nanoparticles were prepared by two methods: (1) direct reduction of Ag+ ions with NaBH4 in aqueous AgNO3 solution containing MS, (2) in situ reduction of Ag+ ions adsorbed on TFMS with NaBH4. The characteristics of products from both methods were compared using SAXRD, TEM, and N-2 adsorption-desorption. Ag nanoclusters were mostly confined and dispersed in the channels of the TFMS and their sizes were under 6 nm. However, Ag nanoparticles on the MS formed outside the mesoporous channels rather than within them. | - |
