Aus dem Max-Planck-Institute für Kolloid- und Grenzflächenforschung Abteilung Kolloidchemie Nonaqueous Syntheses of Metal Oxide Nanoparticles and Their Assembly into Mesoporous Materials Dissertation zur Erlangung des akademischen Grades "doctor rerum naturalium" (Dr. rer. nat.) in der Wissenschaftsdisziplin "Kolloidchemie" eingereicht an der Mathematisch-Naturwissenschaftlichen Fakultät der Universität Potsdam von Jianhua Ba Potsdam, im Juni 2006 给我最最亲爱的爸爸妈妈 给我最爱的晓菡 Nonaqueous Syntheses of Metal Oxide Nanoparticles and Their Assembly into Mesoporous Materials Jianhua Ba Abstract This thesis mainly consist of two parts, the synthesis of several kinds of technologically interesting crystalline metal oxide nanoparticles via nonaqueous sol-gel process and the formation of mesoporous metal oxides using some of these nanoparticles as building blocks and amphiphilic block copolymer as template via evaporation induced self-assembly (EISA) technique. In the first part, the experimental procedures and characterization results of successful syntheses of crystalline tin oxide and tin doped indium oxide (ITO) nanoparticles are reported. SnO nanoparticles exhibit monodisperse particle size (3.5 nm in average), 2high crystallinity and particularly high dispersibility in THF, which enable them to become the ideal particulate precursor for the formation of mesoporous SnO .
