| 本論文利用新型材料八氨丙基倍半硅氧烷，采用水相還原法制備PtCo/POSS，通過高分辨率透射電鏡（HR-TEM）、掃描電子顯微鏡（SEM）對催化劑的微觀結構及形貌進行表征，并對其進行甲酸電催化氧化性能的測試。結果表明利用POSS載體可得到粒徑較小的催化劑顆粒。在所制催化劑中Pt0.75Co0.25/POSS展現(xiàn)出最好的活性。摻雜適量的Co金屬，會增強Pt對甲酸電催化性能，減少COad有毒中間體的吸附，降低CO的氧化電位。 |

| Employing aqueous phase reduction method, PtCo/POSS was prepared with a novel material octaaminopropyl polyhedral oligomeric silsesquioxane. The microstructure and morphology of the catalyst were characterized by means of High Resolution Transmission Electroinc Microscropy (HR-TEM) and Scanning Electronic Microscopy (SEM). Moreover, a test for its electro-catalysis and oxidation properties was conducted in methane acid. Results show that finer catalyst particles could be obtained using POSS carrier. Of all the catalysts, Pt0.75Co0.25/POSS demonstrates the best activity. Doping a certain amount of Co will improve the property of electro-catalysing methane acid of Pt and decrease the absorption of toxic intermediate CO and the oxidation potential of CO. |

PtCo/ POSS采用水相還原法，制備了一種新型的材料octaaminopropyl多面體低聚倍半硅氧烷。催化劑的結構和形貌特征通過高分辨透射美電子Microscropy（HR TEM）和掃描電子顯微鏡（SEM）。此外，甲烷酸的電催化氧化性能進行了測試。研究結果表明，可以得到更好的催化劑顆粒使用POSS載體的。所有的催化劑，Pt0.75Co0.25/POSS演示的最佳活動。一定量的Co摻雜提高屬性電催化作用的甲烷的酸的Pt和降低毒性中間體CO的吸收的CO的氧化電位 能力有現(xiàn)，不知對你是否有幫助，如有問題，不寧賜教�。。�  |

In this thesis, new materials eight aminopropyl silsesquioxane, the use of water to restore the prepared PtCo / POSS by high-resolution transmission electron microscopy (HR-TEM), scanning electron microscopy (SEM) microscopic structure and shape of the catalystappearance was characterized, and its formic acid electrooxidation performance of the test. The results showed that the smaller particle size of the catalyst particles can be obtained using POSS carrier. In the prepared catalyst Pt0.75Co0.25/POSS showing the best activity. Doped with Co metal will enhance the performance of Pt towards formic acid electrooxidation, reduction of COad toxic intermediates adsorption, reduce the CO oxidation potential. 能力有現(xiàn)，不知對你是否有幫助，如有問題，不寧賜教�。�！ |

| Employing aqueous phase reduction method, PtCo/POSS was prepared using a novel material octaaminopropyl polyhedral oligomeric silsesquioxane with chloroplatinic acid and cobalt dichloride as metal sources. Different catalysts were obtained by changing the ratio of Pt and Co. The microstructure and morphology of the catalyst were characterized by means of High Resolution Transmission Electron Microscropy (HR-TEM) and Scanning Electron Microscopy (SEM). Moreover, a test for its electro-catalysis and oxidation properties was conducted in methane acid. Results show that finer and better dispersed catalyst particles could be obtained using POSS carrier. Pt0.75Co0.25/POSS, of all the prepared catalysts, demonstrates the best activity by comparison. Doping a certain amount of Co could improve the property of electro-catalysing methane acid of Pt and decrease the absorption of toxic intermediate CO and the oxidation potential of CO. |
