采用自组装方法制备了一系列介孔氧化铝负载的Ni纳米颗粒催化剂。通过透射电子显微镜、FTIR光谱、热重分析和X射线衍射对催化剂进行表征。该催化剂对异佛尔酮的C=C键加氢反应具有良好的催化性能。具有短通道的介孔结构使反应物快速进入活性中心并及时从催化剂中输出产物，被认为对于获得高活性和高选择性是重要的。
A series of mesoporous alumina‐supported Ni nanoparticles catalysts were prepared using a self‐assembly method. The catalysts were characterized by transmission electron microscopy, FTIR spectroscopy, thermogravimetric analysis, and X‐ray diffraction. The catalysts showed good performance in the hydrogenation of the C=C bond in isophorone. The mesoporous structure with short channels, which afford the reactants rapid access to the active sites and timely export of the products from the catalyst, is believed to be important for obtaining both high activity and high selectivity.
