本文对非晶态合金催化剂的制备及在催化领域中的应用进行了评述。通过骤冷法、化学还原法、浸渍还原法可以得到满足不同催化反应需要的非晶态合金催化剂,并可以通过制备条件的变化调变催化剂的性能。制备过程中焙烧温度、负载量以及不同催化剂载体的选用都会影响所得催化剂的性能。非晶态合金催化剂的非晶态结构、表面形态、活性中心分布等可以通过XRD、EXAFS、DSC、SEM、TEM、XPS等方法进行表征、定性。对于非晶态合金催化剂在含有不饱和基团化合物加氢反应中的研究、应用进行了阐述。
In this paper, the preparation of amorphous alloy catalyst and its application in the field of catalysis are reviewed. Amorphous alloy catalysts which can meet the needs of different catalytic reactions can be obtained by quenching method, chemical reduction method and impregnation reduction method, and the performance of the catalyst can be modified by changing the preparation conditions. The calcination temperature, loading, and the choice of catalyst support during the preparation process all affect the performance of the resulting catalyst. Amorphous alloy catalyst amorphous structure, surface morphology, active site distribution can be characterized by XRD, EXAFS, DSC, SEM, TEM, XPS and other methods. The research and application of amorphous alloy catalysts in the hydrogenation of unsaturated group-containing compounds are described.
