Abstract:	本實驗是以初濕含浸(Incipient-Wetness)的方式來合成單金屬(M/C)觸媒，及用共沉澱(co-precipitation)的方式來製備雙金屬(PtM/C)觸媒，並以活性碳(Vulcan XC72R)來作為其支撐物。首先，先用TPR (Temperture- Programmed Reaction)找出還原溫度再用氫氣去活化，WDS或EDS確保完全還原。接著用ICP(Inductively Coupled Plasma)及TEM (Transmission Electron Microscope)來測得其金搷t量、顆粒大小及分布情形。最後，再配合CV(Cyclic Voltammetry)來測試觸媒對甲醇氧化的電化學活性及吸附CO的氧化電位，利用測得的結果來探討第二金屬的影響效應。 In our experiment, we synthesized the carbon supported monometal (M/C) catalysts and bimetal (PtM/C) catalysts by Incipient-Wetness and co-precipitation. First, we located the reductive temperature of catalysts with TPR (Temperture- Programmed Reaction). Then we used hydrogen for activation and WDS or EDS to confirm the completely reduction. The metal abundance and particle size distribution are characterized with ICP (Inductively Coupled Plasma) and TEM (Transmission Electron Microscope). Finally, we used CV (Cyclic Voltammetry) to test the methanol oxidative voltage and the CO stripping voltage and identify the catalysts’ electrochemical activity. According to the result, we discussed the effects of the second metal in the reactions.
