Abstract: Titanium dioxide based nanostructures and the related self-assembling processes have been investigated in this thesis. In the work, TiF4 has been used as precursor and wet chemistry methods such as liquid phase deposition and hydrothermal process have been applied. Firstly, controlling of nucleation processes including homogeneous and heterogeneous ones in the growth of anatase TiO2 on a common glass substrate has been examined. Secondly, anatase TiO2 microplatelet arrays and hexagonal superlattice arrays on (010) surface of I?-MoO3 have been fabricated. Thirdly, hollow anatase TiO2 nanospheres and nanointestines have been prepared via Ostwald ripening under hydrothermal conditions or a one-step solvothermal process in a quasi reverse emulsion medium. Fourthly, one dimensional (1D) titania and titania/ZnO nanocomposites including TiO2/H2Ti5O11a??H2O, ZnO/H2Ti5O11a??H2O, ZnO/TiO2/H2Ti5O11a??H2O and ZnO/TiO2 with novel superstructures were designed and then synthesized successfully. Finally, rutile-like SnO2 hollow octahedra have been prepared with a new type of a??oriented attachmenta??.
