Реферат:
It was obtained that the selectivity of La2O3-Al2O3 oxides in the NO reduction by H2 depends on the La2O3 concentration and reaction temperature. The surface area as well as the structure of the supports is varied with the lanthana concentration. All mixed supports are highly selective to the production of N2 when the catalytic reaction is conducted at 973 K.
La 3d5/2 binding energy measured for mixed supports is higher than that reported for La2O3 and it is comparable with value published for dispersed lanthanum phases in alumina. XRD data also show that lanthanum is highly dispersed in Al2O3.
Lanthana concentration does not influence significantly on NO conversion with temperature neither for Pd catalysts nor for supports with an exception for 50 % La2O3-Al2O3 support. Its activity is higher than activity of other supports.
Application of coprecipitation method for preparation of La2O3-Al2O3 supports results in: 1) significant enhance of N2 selectivity (at high temperatures) on La2O3-Al2O3 supports and Pd/La2O3-Al2O3 catalysts and 2) increase of NO conversion on La2O3-Al2O3 supports compared with sol-gel method.
