采用溶胶 - 凝胶法制备了一种Rh/AlO(OH)催化剂。该催化剂在相对温和的条件下对喹啉完全加氢生成十氢喹啉表现出优异的催化性能。在热处理过程中，Rh颗粒尺寸的增大以及表面羟基数量的减少导致催化性能显著下降。新鲜的Rh/AlO(OH)催化剂的优异催化性能归因于载体上的羟基与活性金属中心上的羟基之间的协同作用。© 2012爱思唯尔有限公司。保留所有权利。
An Rh/AlO(OH) catalyst was prepared by a sol-gel method. This catalyst showed an excellent catalytic performance for the complete hydrogenation of quinoline to decahydroquinoline at relatively mild conditions. The growth of Rh-particle size and the decrease in the number of surface hydroxyl groups during heat treatment resulted in a significant decrease in catalytic properties. The excellent catalytic performance of the fresh Rh/AlO(OH) was attributed to the cooperation between the hydroxyl groups on the support and on the active metal centers. (C) 2012 Elsevier B.V.
