摘要
用L-苯丙氨酸衍生物的自组装体作为模板,四甲基氢氧化铵为催化剂,经溶胶-凝胶过程,制备出蠕虫状介孔二氧化硅纳米空心结构材料.表征结果显示,该二氧化硅的长度约为100～150nm,直径约30～50nm.介孔孔道平行于壳的表面,孔径为3.8nm.
Silica nanoworms with single-layer of mesopores in their shells were prepared through a sol- gel transcription approach using the self-assemblies of a ehiral low-molecular-weight amphiphile derived from L-phenylalanine as templates and tetramethylammonium hydroxide as catalyst. The characterization results show that length of wormlike silica hollow nanostructure materials is in the range of about 100-150 nm and the width ranges from about 30 to 50 nm. The diameters of the pore channels in the shells are around 3.8 nm.
