報(bào)告簡(jiǎn)介:

Semiconductor oxides (such as TiO2 or ZnO) have attracted more and more attentions since they have great potential applications including solar cells, sensors, photocatalysts, light-emitting diodes and biomedicine, due to their non-toxicity to humans and environment, good mechanical and chemical stability. One-dimensional semiconductor oxide nanostructures such as nanorods, nanowires, nanobelts, and nanotubes oxides nanostructures exhibit superior physical properties as compared with conventional bulk materials, which mainly arise from the quantum-confinement effects and their large specific area, therefore, many efforts have been made to achieve such nanostructures. Here, aligned one-dimensional semiconductor oxide nanostructures for solar energy and environmental applications were fabricated and characterized. Especially, highly ordered TiO2 nanotube and ZnO nanowire arrays were prepared by anodization of titanium foils or titanium films deposited on transparent conductive oxide glass in ethylene glycol containing fluorine ions. Under mild hydrothermal conditions, oriented single-crystalline TiO2 nanowire arrays grows directly on a fluoride-doped tin oxide substrates are also prepared and characterized for high efficient solar cells. Finally, the as-prepared TiO2 and ZnO nanostructure arrays were studied and used for solar cells including dye-sensitized solar cells, quantum dot sensitized solar cells, and photocatalytic applications.
