E&B Nanotech株式会社，韩国庆吉岛426-901 2011年6月20日验收2011年8月11日通过多核固体核磁共振实验研究了纳米二氧化硅在水热处理和3-氨基丙基三乙氧基硅烷(3-APTES)表面改性过程中的局部结构变化。以廉价的硅酸钠为二氧化硅前驱体，采用溶胶-凝胶聚合法制备了纳米多孔二氧化硅。vbl.使用
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
