| dc.description.abstract | 在本研究中我們利用直接成長奈米碳管的方式來合成氧修飾的奈米碳管，探討在製程中加入氧氣對於成長奈米碳管的影響，並利用此碳材應用在甲醇氧化觸媒載體的應用。我們利用穿透式電子顯微鏡及場發射電子顯微鏡來觀察我們成長的含氧奈米碳管表面形貌，並以傅立葉紅外線光譜和電子能量損失圖譜來確認表面含氧的官能基的分佈。 我們利用射頻磁控濺鍍機將白金觸媒佈植於直接成長含氧奈米碳管(Pt/O-CNT)以及一般奈米碳管上(Pt/Untreated-CNT) ，並利用電化學的實驗來分析碳材載體對觸媒活性的影響。在甲醇氧化反應的測量中我們發現到氧修飾的奈米碳管有增進白金觸媒活性的現象，與Pt/Untreated-CNT相比，Pt/O-CNT可以提升80%的甲醇氧化電流，因為碳管表面含氧官能基的貢獻使得白金觸媒毒化的現象降低不少，因此在氧化甲醇實驗中得到良好的效果，而且含氧官能基均勻的分佈在碳管表面，增強白金觸媒和碳材之間的作用力，減少白金觸媒聚集的現象，因此在穩定度方面也有不錯的結果。 | zh_TW |
| dc.description.abstract | We study the effect of oxygen incorporation in carbon nanotube for the application as catalyst support in methanol oxidation reation (MOR). We dope oxygen into the microwave plasma enhanced chemical vapor deposition during the CNT growth; oxygen-containing functional groups can form on the side wall of the CNTs, which can enhance the catalystical activity of platinum in MOR. By comparing the activity of Pt/OCNT with different oxygen content, an 80% increasment in the activity has been achieved with oxygen incorporation. Detailed Raman, FTIR, XPS, TEM EELS analysis and long-term stability test have been performed on the Pt/OCNTs for MOR. | en_US |
