Abstract: In this thesis work, by virtue of promising building units of gold nanoparticles, we have explored several novel preparative strategies to obtain complex nanostructures with high process flexibility and feature application performance. These approaches belong to self-assembly approaches including templated assembly and template-free assembly. In particular, for the first time, the parallel unidirectional 1D-assemblies of gold nanoparticles, spherical aggregative forms such as discrete, linear, and two-dimensional arrays, nanostructured Au sponges with a template-free approach, mesoporous gold spheres under a hydrothermal method, PVP-assisted gold sponges and Au/TiO2/CNTs nanocomposites have been prepared via self-assembly of gold nanoparticles covered with surfactants. By tailoring preparative parameters, excellent product controllability and high morphological yield have been achieved. Meanwhile, the formation mechanism and materials characterization have been investigated systematically. In principle, these findings can be extended to other transition/noble metal nanoparticles using organic surfactants.
