Outline of Final Research Achievements

In this work, we tried to synthesize porous nano assemblies comprising metal oxide nanocrystal. We synthesized cerium oxide nanocrystal in the presence of amino acid, which can bind cerium oxide nanocrystals. In the cubic product, the primary nanoparticles had well-ordered structures. We also found that the primary nanoparticles were disordered with shorter reaction time. They gradually became ordered with increasing reaction time. In addition to the assembly of nanoparticles, we also tried to synthesize porous structure of TiO2 and ZrO2 to realize porous metal oxides.
