製備一維二氧化釩奈米管之研究

The study of preparing one way dimension vanadium oxide nanometer tube

指導教授 : 楊重光 張玉岑

摘要


本研究分為兩部分,包括:(1)以商用鋁板(#1070)做為鋁陽極處理膜(Anodic Aluminum Oxide, AAO)之基材,製作奈米模板。(2)使用奈米模板利用化成處理法製備氧化釩(VxOy)奈米柱。 鋁板經電解拋光後,利用不同濃度的硫酸與草酸之電解液於實驗條件控制下經過陽極處理(AAO), 獲得不同深寬比之奈米模板,以場發電子顯微鏡(Field emission-scanning electron microscope, FE-SEM)及能量散射光譜儀(Energy dispersive spectrometer, EDS)觀察獲得約40~80nm之奈米孔洞。鋁板經電化學製程後,表面會形成具高孔隙度、均一孔徑、規則孔洞分佈之高品質奈米模板薄膜,使用化成處理法,利用釩酸鈉(Na3VO4)溶液為化成液,並利用外加電壓輔助,使釩離子能沉積於AAO模板內,乾燥後VxOy奈米柱方可形成。將以上所製作之VxOy奈米柱,以磷酸(5vol%)於恆溫(25℃)下移除奈米模板,製成奈米柱,利用化學分析能譜儀(Electron Spectroscopy for Chemical Analysis, ESCA)分析其化成產物及研究產物之物理、化學性質。

This study is divided into two parts. First, the commercial aluminum (# 1070) as anodized aluminum films (Anodic Aluminum Oxide, AAO) of the substrate is used to produce nanotemplates. Second, nanotemplates with using Chemical treatment were prepared vanadium oxide (VxOy) nanorods. Polished aluminum by electrolysis, using different concentrations of sulfuric acid and oxalic acid in the experimental conditions of the electrolyte through the anode under the control of processing (AAO), to obtain nano particle with different aspect ratio of template in field emission electron microscope (Field Emission-Scanning Electron Microscope, FE-SEM) and energy dispersive spectroscopy (Energy Dispersive Spectrometer, EDS) observation of about 40~80 nm nano holes. Aluminum by electrochemical process, the surface will form a high porosity, uniform pore size, pore distribution of the rules of high-quality thin film nanotemplates, use the conversion treatment method using sodium vanadate (Na3VO4) solution as the liquid, and use additional auxiliary voltage, so that vanadium ions can be deposited in the AAO template, the dry VxOy nanorods until be formed. It will be produced above the VxOy nanorods phpsphate(5vol%) at constant temperature(25℃) to remove the nanotemplates, made nanorods by ESCA(Electron Spectroscopy for Chemical Analysis, ESCA). Product and research analysis into the product of the physical and chemical properties.
