英文摘要: The combinatorial chemistry and high through-put screening technique have received considerable attention owing to their potential application. In an effort to discover new materials with useful properties, the combinatorial chemistry has been established as one of the most important methodology, which is capable of decreasing the discovery process in hundreds and thousands times. In this paper, the development of a high through-put screening technique for heterogeneous catalysts based on the UV absorption spectrum technique, named UV absorption array, is reported. The application of the high through-put screening technique in combinatorial discovery of active catalysts for the selective catalytic reduction of NOx with CH4 is also demonstrated. According to the variation of UV light intensity, owing to the UV absorption of organic compounds, the relative quantity of the reactants or the products before and after reaction could be obtained. By using this method, the Co-Ce/HZSM-5 samples with different m (Co) /m (Ce) ratios were investigated. The catalyst with w (Co) = 2.5 % and m (Co) /m (Ce) = 2 showed remarkable activity and its active factor R was up to 0.67. This simple and cheap multiple channel setup can also be applied for the selection of other heterogeneous catalysts by changing the UV source.
