此實驗利用定電位沉積的方法，浸入銦錫氧化物之導電玻璃上，後續並測量電甲醇氧化的催化效果，變動參數上使用電位選擇、錯合劑三乙醇濃度選擇，及電沉積時間的長短，及使用欠電位沉積TEA-PdIr 表面上，利用X-光繞射儀(XRD)、能量分散式光譜儀(EDS)、掃描式電子顯微鏡(SEM)與循環伏安法(CV)，分析其結晶的程度，顆粒的大小，元素的組成比例，表面的形貌，及最終電甲醇氧化催化效率。由最終電甲醇氧化效率的結果，於沉積電位於-0.4 V 下之所備至鈀銥合金催化效率並沒有優於純鈀且也容易產生脫膜的現象。於添加三乙醇胺(TEA)所生成的合金薄膜可以有效增加電沉積時間，並且增加電甲醇的氧化效率，但合金狀態並沒有明顯超過單純純鈀電甲醇氧化，隨著第三變動因素，時間的拉長，可以觀察到PdIr 合金甲醇電氧化部分可以跟純鈀薄膜不相上下，因純鈀會產生CO 毒性問題，那PdIr 就可以有效降低此一現象發生，而在添加0.1 M TEA 下電沉積時間900 s，Pd+2 及Ir+3 離子比例電沉積液9:1，Ir 的含量只占2.43 %，有最佳甲醇電氧化效率。

The experiment of PdIr thin film is fabricated by the co-electrodeposition on the indium tin oxide (ITO) of Conductive glass coated PdIr, and thus gets the catalytic efficiency in methanol electro-oxidation. There are four changed parameters included in this experiment: select the deposition potential, concentration of triethanolamine (TEA), time of electrodeposition, and Ir underpotenial deposition (UPD).
The effect found by the researcher is that -0.4 V will be able to form electrodeposition of PdIr alloy film on the ITO glass. However, the efficiency of catalyst is not high enough compared to pure Pd film, and another phenomenon is that desorption takes place in the process of methanol electro-oxidation. The following is to add TEA to electrodeposition solution, the researcher finds that TEA not only increases the time of electrodeposition but also improves the current density of the methanol electro-oxidation. Consequently, 0.1 M triethanolamine is added to the electrolyte, which makes the PdIr alloy film abtain more homogeneous and adhesive easily with ITO. As to final factor, the researcher increases the time of bimetallic electrodeposition to 900s, and gets the same value as pure Pd thin film in methanol electro-oxidation. Although it’s not excellent in methanol electro-oxidation, the metallic PdIr thin film of poisoning resistance is better than pure Pd thin film.
