摘要


近年來,由於二氧化鈦物理化學特性的研究快速發展,使其成功地被應用在光催化反應中作為觸媒材料。在本研究中,我們利用陽極氧化法,藉由含氟化物電解質製備了二氧化鈦奈米管薄膜。首先,經由不同的實驗控制變因(如電解電壓、電解電流、電解時間、電解質溶液溫度、pH、與不同重量比的甘油水溶液),及不同pH的染料溶液的狀況下,測試不同形態觸媒對甲基藍及甲基橙之光催化反應的特性。由本研究的實驗結果顯示,奈米管薄膜的管長與電解電壓大小、電解時間長短有關,且會造成不同的光催化反應速率;但管徑變化對光催化反應速率的影響,則呈正相關係,於大管徑下呈不規則變化。煅燒溫度提升後,奈米管薄膜的晶相會轉變成銳鈦礦與金紅石更高溫時,趨向金紅石。不同溶液pH值與不同的奈米管晶相,都會影響染料的光催化反應速率。本研究所製備二氧化鈦奈米管膜及實驗相關結果,有應用於化學感測器與太陽能電池的潛力。

Recently, progress on research of physical and chemical properties of TiO2 had brought it great application in the photocatalytic reactions. In this study, TiO2 nanotube arrays were prepared with electrolytes containing fluoride by anodic oxidation method. Different operation conditions were investigated including electrolysis voltage, electrolysis current, electrolysis time, electrolyte solution temperature, electrolyte solution pH, and weight ratio of glycerin in aqueous solution. Nanotube arrays of difference lengths and diameters were fabricated. Photocatalytic reactions of methylene blue and methyl orange were implemented with difference nanotube arrays, calcination temperature and dye solution pH. The results showed nanotubes length was according to electrolysis voltage and electrolysis time and related to photocatalytic ratio, but nanotubes diameter was only proportional to photocatalytic ratio at low and middle diameters. As calcination temperature increased the crystal phases of TiO2 were transferred from amorphous to anatase and rutile phases. The photocatalytic ratio of dyes was also influenced by crystal phases of nanotube arrays and dye solution pH. The results concluded in this study have potential applications in the researches of chemical sensor and solar cells.
