英文摘要	a series of mesoporous cu-mn-al2o3(cma) materials was synthesized at moderate temperature and their structures were characterized by xrd. n-2 physical adsorption and tpr techniques. it was found that using metal complex ion[cu(nh3)(4)(2+)-mn(nh3)(6)(2+)] as raw materials is easier to form good-structure mesoporous cu-mn-al2o3 materials than using its nitrate salt [cu(no3)(2)-mn(no3)(2)]. the tpr tests. results indicate that cuo and mno. were homogeneously dispersed in the mesoporous materials. their catalytic application to preferential catalytic oxidation of co in a hydrogen-rich stream was studied. the activity varies in the order of cma(1:1, molar ratio)> cma(1:2)>cma(2:1)>cma(cp)>cma(1:0)approximate to cma(0:1). the cma(1:0) and cma(0:1) have lower activity compared to other samples, implying that there existed coordination effect between cu-mn in the samples. the selectivity varied in the order or cma(0:1)>= cma(1:2)>cma(1:1)>cma(2:1)>cma(1:0) at higher temperature (>= 120 degrees c), indicating that increasing the cu content enhanced the conversion of h-2. the sample cma(cp) made by coprecipitation method has a lower co oxidation activity and selectivity than its counter-parts of mesoporous cu-mn-al2o3 materials[cma(1:2)], this attributed to the lower surface area of the former and poor interaction of cuo with mnox.
