| Summary: | 碩士 === 國立臺北科技大學 === 化學工程研究所 === 100 === Semiconductor metal oxides such as TiO2, Ta3N5, and Ag3VO4 are often treated as the photocatalysts for light-induced photo-oxidation of water. Previous studies in our group have shown that vanadium oxides particles were photocatalysts for water-splitting. However, the performance of catalysts can vary significantly by its surface morphology. As a result, this study aims to investigate the hydrogen production capability of vanadium oxides with 1-D nano-structure. The commercial aluminum (#1070) was firstly anodized to aluminum films (Anodic Aluminum Oxide, AAO) as the nano-scale templates. Then, vanadium oxide nanorods were fabricated and deposited finto the template through electrodeposition method. In addition, design of experiment accompanied with ANOVA was applied to analyze the significance of the control factors including concentrations of sodium vanadate, applied voltage, and deposition time. The properties of vanadium oxide nanorods were characterized by ESCA(Electron Spectroscopy for Chemical Analysis), FE-SEM (Field Emission-Scanning Electron Microscope) and EDS (Energy Dispersive Spectrometer).
