Abstract
The thesis is divided into three parts. In the first part, we modulated the morphology of mesoporous silica SBA-15 in the presence of ZrOCl2 by controlling several synthesis parameters, such as silica source, the concentration of surfactant and silica source, the concentration of ZrOCl2, the value of pH, or by changing the time for stirring after the addition of silica source. The synthesis parameters were controlled in order to obtain platelet SBA-15 with large area and thin thickness. The high content of Zr4+ on the SBA-15 surface could catalyze the polymerization of furfuryl alcohol, thus in the second part, we synthesized CMK-5-like platelet mesoporous carbon by nanocasting and the platelet SBA-15 was used as hard template. In the third part, monomers of various polymers were polymerized inside platelet mesoporous carbon by free-radical polymerization. We used these polymer/mesoporous carbon nanocomposite as sensing materials and applied on gas sensor for gas detection.
