於室溫下進行陽極氧化反應，使用由碳酸氫鈉與碳酸鈉組成之緩衝溶液作為陽極氧化過程中的電解質，調控製備氧化鋅奈米管/奈米線結構陽極氧化過程的實驗參數進行條件優化，其影響變因有電解質濃度、電解質pH值、陽極氧化電壓、陽極氧化持續時間，再藉由高解析度掃描式電子顯微鏡 (SEM) 對氧化鋅奈米管/奈米線結構進行表面形貌分析，能量分散式光譜分析儀 (EDS) 與化學分析電子光譜儀 (ESCA) 進行元素表面組成分析，X射線繞射儀 (XRD) 鑑定氧化鋅晶體結構，紫外光/可見光光譜儀 (UV-Vis) 測量紫外/可見光漫反射光譜求得氧化鋅能隙值，陽極氧化反應製備氧化鋅奈米管/奈米線結構最適化條件依電解質濃度、電解質pH值、陽極氧化電壓、陽極氧化持續時間、退火溫度分別為 10 mM、pH 10.25、8 V、360 s、400℃ ，以此條件下製備氧化鋅奈米管/奈米線結構應用於光催化反應降解玫瑰紅B染料，並探討不同變因對光催化反應之影響及穩定度測試。
在光催化降解玫瑰紅B染料的實驗，為了提高原先氧化鋅奈米管/奈米線結構之光催化活性，促進光生電子電洞對之分離效率，透過化學浸漬法修飾金屬鈀對氧化鋅改性，其能隙值也由3.21 eV 縮小至3.15 eV，未修飾金屬鈀之氧化鋅奈米管/奈米線結構光催化降解率為 23.9% ，修飾金屬鈀後的氧化鋅奈米管/奈米線結構光催化降解率提升至39.6%。

In this work, a low-cost and non-toxic zinc oxide photocatalyst was prepared by an environmentally friendly method. Zinc oxide nanotube/nanowire structure was formed on the surface of a zinc metal substrate by anodic oxidation. The prepared zinc oxide nanotube/nanowire structure was characterized by high resolution scanning electron microscope (HR-SEM), energy dispersive spectrometer (EDS), X-ray diffractometer (XRD), electron spectroscopy for chemical analysis (ESCA), ultraviolet/visible spectrometer (UV-Vis). Optimization of the experimental parameters for the preparation of zinc oxide nanotube/nanowire structure depends on the electrolyte concentration, electrolyte pH, anodizing voltage, anodizing duration and annealing temperature. Zinc oxide nanotube/nanowire structure was used for the photocatalytic degradation of rhodamine B dye. In order to enhance photodegradation activity of rhodamine B in aqueous solution, by modification of metal palladium on zinc oxide nanotube/nanowire structure to promote the separation efficiency of photogenerated electron-hole pairs. The degradation rate of RhB increased from 23.9% to 39.6%.
