Abstract
The thesis is divided into three parts. In the first part, mesoporous carbon materials with rod-like morphology, CMK-3, and those with tube-like morphology, CMK-5, have been synthesized by template synthesis using mesoporous SBA-15 silica as a hard template and sucrose or furfuryl alcohol as carbon precursors. The composition and the structure of these carbon materials were characterized by X-ray diffraction, nitrogen physisorption analysis, thermal analysis and transmission electron microscopy. Based on the data, the synthesis conditions have also been optimized. In the second part, monolithic carbon materials with hierarchically bimodal meso- and macroporosity have been prepared by using a hierarchically meso/macroporous silica monolith as a hard template and phenolic resin as the carbon source. The pore structure of the carbon monoliths were investigated by nitrogen physisorption analysis and scanning electron microsopy. In the third part, carbon-coated magnetic metal nanoparticles have been synthesized by using the carboxylate-functionalized mesoporous SBA-15 silica as a hard template. The magnetic properties of these nanoparticles were studied by Superconducting Quantum Interference Device. In addition, the outer carbon layers on these nanoparticles were oxidized to bear carboxylate groups by the treatment with nitric acid, and Fourier-transformed infrared spectroscopy was applied for characterizations. With these carboxylate groups, the carbon-coated magnetic nanoparticles can be further grafted with a variety of functional groups and other molecules for biomedical applications in the future.
