| 英文摘要 | a catalyst library of 80 samples with different mass ratios of rare earth elements, cobalt (co), cerium (ce), and indium (in), was prepared by impregnation of a fresh hzsm-5 zeolite support. a high-throughput detection setup; based on uv absorption spectroscopy, was developed for heterogeneous catalyst selection. the catalytic properties of the library were tested in the selective catalytic reduction of no by methane at 673 k. among the co/ce series, the catalyst with co/ce = 2:1 and co/h-zsm5 = 2.5% has shown remarkable efficiency (up to 78%). in the ce/in series, the reactivity of the catalyst with the support composition of ce/in = 1:1 and ce/h-zsm5 = 2.0% was <= 88%. our initial experiments definitely indicated that this simple and inexpensive multichannel setup can be applied for the selection of other heterogeneous catalysts. according to the variation of the uv light intensity, resulting from the absorption of the reactant or product, it was possible to monitor the relative quantity of reactants or products during a catalytic reaction. |
