Syntheses and structural control of silicide, oxide and metallic nano-structured materials

摘要

The structural control and morphological modification of a series of silicide, oxide and Ag metal nanostructures have been farther discussed with reviews of nanostructure syntheses, such as CrSi_2 nanowire bundles - dendrites, MoSi_2 nanosheets, α-Fe_2O_3 nanowires - nanobelts, CuO/Cu_2O nanowire axial heterostructures, ZrO_2/SiO_x and CrSi_2/SiO_x core/shell nanowires. In addition, the syntheses of Ag - three-dimensional dendrites, two-dimensional dendrites, two-dimensional fractal structures, particles and nanowires also were discussed. Moreover, the structural and morphological properties of the nanostructures were examined. The structural control and morphological modifications of the nanostructures have been successfully demonstrated by the appropriate thermal treatments with specific starting materials. A large volume of silicide nanowire bundles, large area of oxide nanowire arrays and large area Ag nanostructure coatings were successfully fabricated.
