To properly utilize the anisotropic properties of 1-D nanostructured metal-oxide arrays in applications with high performance, the influences of the fabrication parameters on the properties of the prepared materials, such as geometries, crystallinity, and shapes, will be systematically investigated. The growth of the 1-D nanostructured metal-oxide arrays will be controlled onto the selected substrates and positions, followed by the filling of the 1-D nanostructures with the metal-oxide nanoparticles using electrophoresis deposition and novel one-step template-assisted method. The functionalization of the metal nanoparticles and metal-oxide layers on the above prepared materials will be carried out by the photochemical method and the wet-chemical route. The prepared novel 1-D nanostructured metal-oxide arrays will act as highly efficient photocatalysts and photoanode in the applications of photocatalysis and photoelectrocatalysis to completely transform the emerging contaminats (e.g., pharmaceuticals and personal care products, PPCPs) into environmentally benign end-products. This project will allow us to better understand the related mechanisms on the growth of 1-D nanostructures and the toxicity of PPCPs in order to develop more environmentally friendly PPCPs treatment techniques with nanotechnology.一維奈米結構奈米顆粒電化學電泳沉積法光催化光電催化乙醯氨酚異布洛芬one-dimensional nanostructured materialsnanoparticleselectrochemicalelectrophoresis depositionphotocatalyticphotoelectrocatalyticPPCPs陣列式一維奈米結構金屬氧化物的製備、表面修飾及其在環境上之應用
