| 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. |

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(duì)你是否有幫助,如有問(wèn)題,不寧賜教。! |

能再幫我翻譯一下嗎,有點(diǎn)改動(dòng),謝謝啦。 本論文利用新型材料八氨丙基倍半硅氧烷,以氯鉑酸及二氯化鈷為金屬源,采用水相共還原法制備PtCo/POSS,改變Pt和Co的比例得到不同的催化劑。通過(guò)高分辨率透射電鏡(HR-TEM)、掃描電子顯微鏡(SEM)對(duì)催化劑的微觀結(jié)構(gòu)及形貌進(jìn)行表征,并對(duì)其進(jìn)行甲酸電催化氧化性能的測(cè)試。結(jié)果表明利用POSS載體可得到粒徑較小、分散較好的催化劑顆粒。通過(guò)比較,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(huì)增強(qiáng)Pt對(duì)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。 |
