| 英文摘要 | 采用浸渍法制备了不同晶相组成的TiO2负载的PtCo双金属催化剂,采用X射线粉末衍射、拉曼光谱、N2物理吸附、CO化学吸附和H2程序升温还原等技术对其进行了表征,并考察了催化剂的低温苯加氢反应性能.结果发现,不同晶相组成TiO2负载的PtCo双金属催化剂CO化学吸附量及催化活性有显著差异,当以含有少量金红石相的TiO2为载体时,催化剂加氢性能优于单一金红石或锐钛矿相TiO2负载的催化剂.; PtCo bimetallic catalysts supported on TiO2 with different phase compositions were prepared by the impregnation method and evaluated using benzene hydrogenation at relatively low temperatures. The catalysts were characterized by X-ray diffraction, Raman spectroscopy, N-2 physisorption, CO chemisorption, and H-2 temperature-programmed reduction. The results showed that the catalyst properties can be altered by adjusting the phase composition of TiO2, Mixture phase of anatase and rutile supported PtCo bimetallic catalysts possessed higher CO chemisorption capacity and hydrogenation activity compared to pure rutile or anatase supported catalysts.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000270149200006&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 1; 08; 748-752; 30 |
