Several ternary oxides CuCeZrO_(y)(CCZ)were synthesized by a facile grinding method followed by calcination at high temperatures,and used as catalysts for CO oxidation at low *** influences of calcination temperature(400-600℃)on the physicochemical properties of the assynthesized ternary oxides were investigated by thermogravimetric analysis/differential scanning calorimetry(TGA/DSC),X-ray diffraction(XRD),transmission electron microscopy(TEM),Raman,inductively coupled plasma-optical emission spectrometry(ICP-OES),N_(2) adsorption,H_(2)-temperature programmed reduction(H_(2)-TPR),and X-ray photoelectron spectroscopy(XPS)*** results show that the increase in calcination temperature from 400 to 500℃is conducive to the high dispersion of CuOx on catalyst surface and the incorporation of Cu species into the support to form the Cu-Ce-Zr-O solid *** raising of calcination temperature from 500 to 600℃,however,leads to the segregation of Cu species from the solid solution to aggregate on support surface and growth of highly dispersed CuOx *** highest catalytic activity is acquired over the CCZ calcined at 500℃,which can be ascribed to the largest contents of Cu+species and oxygen vacancies owing to the formation of the maximum amount of Cu-Ce-Zr-O solid solution.

The Cu-exchanged SSZ-13 with the small-pore chabazite framework is considered as a highly efficient catalyst for selective catalytic reduction of NO with NH_(3)(NH_(3)-SCR).In order to further improve the catalytic property,a series of Mn ion-assisted Cu/SSZ-13 powder catalysts were prepared by co-exchange method and stepwise exchange *** is found that the NH_(3)-SCR activity,N_(2) selectivity,hydrothermal stability and sulfur resistance of Cu/SSZ-13 are promoted by introducing a minority of Mn(0.15%to 0.23%(mass))through co-exchange *** results reveal that the Cu,Mn co-exchange enables the higher amounts of Cu^(2+)active sites,the abundant medium strong and strong acid,the optimized ratio of Lewis acid to Brønsted acid etc.,which are required for a good NH_(3)-SCR catalytic property over broad temperature range and under harsh working ***,a monolithic catalyst was prepared by impregnating a cordierite ceramic support into the coating slurry containing the optimized CuMn/SSZ-13 *** diesel engine bench tests show that Cu,Mn co-exchange gives the monolith catalyst a better catalytic property than commercial *** work provides an important guidance for the rational design of secondary-ion-assisted zeolites applied in NH_(3)-SCR.

以SSZ-39为载体,采用离子交换法制备不同铜锰物质的量比的Cu-Mn/SSZ-39分子筛催化剂,并考察其在以NH3为还原剂的选择性催化还原NO反应(NH3-SCR)中的脱硝活性。通过XRD、SEM、N_(2)吸脱附、NH_(3)-TPD、H_(2)-TPR、XPS、ICP等对催化剂的结构、形貌、表面酸性等进行表征。结果表明,Cu^(2+)提供主要的反应活性位,使催化剂具有良好的脱硝活性和N_(2)选择性;Mn^(2+/3+)交换提高了催化剂的表面酸性,特别是增加了弱Lewis酸的含量;Cu^(2+)、Mn^(2+/3+)双金属交换的Cu-Mn/SSZ-39催化剂具有良好的低温脱硝活性和水热稳定性。当Cu与Mn的物质的量比为1∶0.6时,Cu-Mn(0.6)/SSZ-39具有最低的起燃温度(T_(50)为125℃),在184~433℃的宽温度范围内NO转化率达到90%以上,并在450℃内保持90%以上的N_(2)选择性。水热老化后的Cu-Mn/SSZ-39-A基本保持了原有的晶型、形貌和脱硝活性,体现了良好的水热稳定性。
