本論文藉由電化學電沉積的方式，在含有氧化銦錫的導電玻璃上製備鈀鉑合金薄膜，並進一步將合金薄膜，用於甲醇電氧化的催化鑑定上。在薄膜製備過程中，使用不同比例的鈀鉑離子溶液，改變沉積電位並找尋其最佳電位，添加三乙醇胺、檸檬酸、酒石酸、草酸等錯合劑於電鍍液中，並尋找最適合的輔助錯合劑，將選定的錯合劑改變其濃度，觀察不同濃度間的差異，最後透過改變沉積電量來改變沉積原子數，探討原子數量不同的合金薄膜的性質。
鈀鉑合金薄膜藉由X-射線繞射儀(XRD)、能量色散X-射線光譜儀(EDS)、掃描式電子顯微鏡(SEM)、電化學分析儀中的循環伏安法(CV)等，鑑定薄膜之合金結構、原子組成比例、薄膜表面樣貌、甲醇電氧化催化效果與電鍍液的電化學性質。
由電化學分析儀中可得知在-0.45 V的沉積電位下製備的合金薄膜具有最佳之甲醇電氧化的催化效果，且添加三乙醇胺的合金薄膜在甲醇電氧化的使用過程中較為穩定，並由最後改變沉積電量結果發現Pd含量較多的合金薄膜，會隨著電量增加進而提升其催化活性，而Pd與Pt比例相近時的合金薄膜，隨著沉積電量增加容易導致甲醇電氧化不穩定的結果。

In this study, we used the electrochemical methods to fabricate PdPt alloy thin film on an ITO coated glass and test its physical and catalytic properties. Our parameters include: deposition potential, ratio of ion concentration, kinds of chelating agent, concentration of triethanolamine (TEA), amount of electricity. The structure, surface morphologies and alloy compositions were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS), respectively. The most important of all, the catalytic efficiency of thin film was examined by cyclic voltammetry (CV).
It was known from the electrochemical analyzer that the alloy thin films prepared at the deposition potential of -0.45 V have the best catalytic efficiency toward methanol oxidation reaction (MOR), and the alloy thin films that manufactured from the plating solution containing triethanolamine were more stable during MOR. The result showed that the catalytic activity of the alloy films with more Pd content increases as the amount of electricity increases. However, the alloy films with more Pt content showed an unstable MOR activity, because large number of catalytic reaction would produce intermediate carbon monoxide and cause Pt to be poisoned.
