以堇青石蜂窝陶瓷为载体,采用涂覆法制备了一系列不同摩尔比的Cu-Co复合氧化物催化剂并测试了催化剂的乙酸乙酯催化燃烧性能。当Cu与Co摩尔比为1:2时,该催化剂(1Cu2Co)具有较高的乙酸乙酯催化活性(T99 = 250℃)。运用X射线衍射(XRD),程序升温还原(H2-TPR),物理吸附(BET)等技术对催化剂进行了表征。结果表明,较高的比表面积(170 m2/g),较小的CuO和CoOx晶粒以及较强的还原性能为1Cu2Co催化剂高活性的主要原因。<br/>A series of Cu-Co catalysts with different Cu-Co mass ratios were prepared via coating method with the cordierite honeycomb ceramic as the carrier, and the catalytic combustion performance of ethyl acetate is tested. The highest activity (T99 = 250?C) occurred at mole ratio of 1:2 for Cu:Co (1Cu2Co). The catalysts were further characterized by X-ray diffraction (XRD), Brunauer-Emmett- Teller (BET), and temperature-programmed reduction (H2-TPR) technologies. The results showed that the main reasons of higher activity of 1Cu2Co catalysts can be attributed to the enhanced reducibility, higher surface area (170 m2/g), and smaller crystal size of CuO and CoOx。
