在本研究中，利用不同鉑前驅物及硝酸銀添加量，並以油胺作為還原劑的反應下，合成出具良好均一性及分散性的圓球狀鉑奈米粒子；同時以相同的反應條件，利用Pt(acac)2及HAuCl4•3H2O分別作為鉑及金的前驅物，來合成鉑-金雙金屬奈米粒子。藉由調控鉑及金前驅物的比例，分別合成出1:1、2:1、1:2的鉑-金雙金屬奈米粒子，再利用場發式穿透式電子顯微鏡（FE-TEM）、能量散射光譜儀（EDS）、X光繞射儀（XRD）、紫外光－可見光光譜儀（UV-Vis）感應耦合電漿發射光譜儀（ICP-OES）及X射線光電子能譜儀（XPS）對鉑-金雙金屬奈米粒子進行特性鑑定。經由酸處理的鉑-金雙金屬奈米粒子被應用於厭氧環境下對三氯乙烯的還原脫氯反應之催化反應，結果顯示未經由酸處理之鉑-金雙金屬奈米粒子的反應速率（0.012 min-1）遠小於經醋酸酸洗之奈米粒子的反應速率（0.085 min-1）；另外，鉑-金雙金屬奈米粒子的擬一階速率常數值為鉑單金屬奈米粒子之擬一階速率常數值的6-7倍。從本研究結果中，可得知鉑-金雙金屬奈米粒子在還原脫氯反應中亦具有良好的催化能力，因此可應用於其他含氯有機物的還原脫氯反應上。
