Abstract
E&B Nanotech Co. Ltd, Gyeonggido 426-901, Republic of KoreaReceived June 20, 2011, Accepted August 11, 2011Multinuclear solid-state nuclear magnetic resonance (NMR) experiments were performed to investigate thelocal structure changes of nanoporous silica during hydrothermal treatment and surface modification with 3-aminopropyltriethoxysilane (3-APTES). The nanoporous silica was prepared by sol-gel polymerization usinginexpensive sodium silicate as a silica precursor. Using
