Nb2O5 promoted Pd/AC catalyst for selective phenol hydrogenation to cyclohexanone
文献摘要：
Phenol hydrogenation is a green route to prepare cyclohexanone,an intermediate for the production of nylon 66 and nylon 6.The development of high-performance catalysts still keeps a great challenge.Herein,the activated carbon(AC)was modified with an acidic material Nb2O5 to adjust the microstruc-ture and surface properties of AC,and the influences of the calcination temperature and Nb2O5 content on the catalytic performance of the Pd/AC-Nb2O5 catalysts for the phenol hydrogenation to cyclohexanone were investigated.The Nb2O5 with proper content can be highly uniformly distributed on the AC surface,enhancing the acidity of the Pd/AC-Nb2O5 catalysts with comparable specific surface area and Pd disper-sion,thereby improving the catalytic activity.The hybrid Pd/AC-10Nb2O5-500 catalyst exhibits the syn-ergistic effect between the Pd nanoparticles and AC-10Nb2O5,which enhances the catalytic activity for the hydrogenation of phenol.Furthermore,the as-prepared Pd/AC-10Nb2O5-500 catalyst shows good reusability during 7 reaction cycles.
