Processing of structural controlled ceramics with Nanospace

采用前驱体溶液法制备了含均匀分散的金属氧化物纳米颗粒的微孔SiO2陶瓷，系统研究了Si-M-O前驱体向复合粉体的转化过程，探讨了纳米间隙复合陶瓷的形成机理。研究了复合材料的微观结构与气体吸附性能的关系。此外，通过透射电子显微镜研究了复合材料对碳微线圈生长的催化诱导作用，并探讨了碳微线圈的形成机理。

Synthesis of microporous silica containing uniformly dispersed metal oxide nanoparticles using precursor solution method has been studied and the transformation of the Si-M-O precursor into the composite powder was investigated systematically to determine the formation mechanism of the composite ceramics with nanospace. The relationship between the microstructure of the obtained composite and the gas adsorption property was investigated. Further, it is found that the composites catalytically induce to grow the carbon micro coil and the formation mechanism of the carbon micro coil was studied by transmission electron microscopy.
