由於奈米粒子獨特的物理、化學性質及在催化反應上所表現出的高活性一直是引起大家注意焦點，由文獻中發現合金及雙金屬奈米粒子的結構及成份組成對工業上的催化反應有極大的改善。我們以雷射法製備出金銀鈀的三合金奈米粒子並探討其催化性質，也以雷射剝削法製備出鉑銠雙金屬奈米粒子。
我們已經成功的以雷射光照射金、銀及鈀的奈米粒子混合溶液製備出分散的金銀鈀三合金奈米粒子，其粒徑分佈為4.4 ± 1.5 nm。並以能量分散光譜及X光粉末繞射儀分析各粒子中的成份比例與結構，最後也以並進一步探討其催化性質，發現其在Heck reaction中具相當好的催化活性。
另外也以雷射剝削法製備出存在於各種溶劑中的鉑銠雙金屬奈米粒子，並以穿透式電子顯微鏡觀察在各種條件下的粒子型態；X光光電子光譜觀察其表面性質；能量分散光譜分析鉑及銠在各粒子中的成份比例，最後也以X光粉末繞射儀鑑定鉑銠雙金屬奈米粒子的結構。

Nanosized metal particles continue to attract interest because of their unique physical and chemical properties and importance of these materials as catalysts. Structure and components of alloy or bimetallic nanoparticles due to the profound improvements in many industrial catalytic processes have been found. In this study we prepared the Au-Ag-Pd and Pt-Ru nanoparticles and to investigate their characterization.
Dispersed alloy-like Au–Ag–Pd nanoparticles with average diameters of 4.4 ± 1.5 nm have been prepared by laser irradiation of a mixture containing gold, silver, and palladium colloids. Au-Ag-Pd nanoparticles were determined by energy dispersive X-ray spectrometer and X-ray powder diffraction. The catalytic activity of the nanoparticles was subsequently investigated and they were found to be efficient catalysts for the Heck reaction.
Bimetallic Pt-Ru nanoparticles have been prepared by laser ablation, and were observe by transmission electron microscopy, X-ray photoelectron spectroscopy. In addition, Pt-Ru nanoparticles also have been analyzed by X-ray powder diffraction and energy dispersive X-ray spectrometer.
