Abstract

Abstract:

K₂Ti₂O₅, which have a high crystallinity, were well prepared by sol-gel method.K₂Ti₂O₅ were characterized by XRD, SEM, and BET surface area and found to have relatively high soot oxidation performance.Certain amount of NO_x has positive influence on the performance of K₂Ti₂O₅, implying that K₂Ti₂O₅may be a kind catalyst for simultaneous removal of NO_x and soot. K₂Ti₂O₅ may be an excellent candidate for soot oxidation due to its high oxidation activity, water-stability, and economical advantages.

Key words:

K₂Ti₂O₅, _, Automobile exhaust, , Soot, , Catalytic oxidation, , NO_x

摘要： 通过溶胶凝胶法制备了K₂Ti₂O₅催化剂，并利用XRD,SEM,BET等方法进行了表征。利用程序升温反应对K₂Ti₂O₅的碳烟催化氧化性能进行了研究。结果表明, K₂Ti₂O₅具有一定的碳烟催化氧化活性。同时，一定量的NO_x有助于K₂Ti₂O₅的催化氧化活性，说明K₂Ti₂O₅是一种潜在的可同时去除NO_x和碳烟的新型催化剂。由于K₂Ti₂O₅对碳烟具有较高的催化氧化活性、较好的抗水性和低廉的价格，因此是一种具有较好发展前景的汽车尾气净化催化剂。
