Abstract:
Metal oxides have widespread usage across many fields, including catalysis, energy storage and conversion, and biomedicine. Design and control of the architecture of metal oxide materials on the nanoscale have attracted great interest in recent years because of the unusual mechanical, optical and electrical properties arising from confining the dimensions of such materials. In this talk, I will present three approaches, including aerosol spray pyrolysis, sol-gel and nanocasting, for tailoring nanostructures of a variety of metal oxide materials, such as titanium oxide, tungsten oxide and vanadium oxide. I will also discuss the structure-property relation of the resultant nanomaterials and demonstrate their improved performances in given applications. In addition, I will present how a simplenano-junction geometry composed of metal oxide nanoparticles and flat metal film can be employed as a convenient and sensitive surface-enhanced Raman scattering sensor, allowing direct tracking and understanding of application-specific transformations at the interface.
