The study and development of CeO2 nanocrystals containing transition-metal species are of crucial importance for understanding the effect of transition-metal species on their catalytic activity. CeO2 nanocrystals containing only 0.61% Cu were demonstrated as an effective catalyst for imine synthesis from amines at 110° using NHPI as radical initiator and air as oxidant. Especially, Cu-doped CeO2 nanocrystals after thermal treatment at 300° for 2 h show high conversion (97.8%) and high selectivity (98.6%) for the synthesis of N-benzylidene benzylamine from benzylamine, as well as acceptable yield for the synthesis of several other kinds of imines from amines. The Cu-doped CeO2 nanocrystals also exhibited excellent cycling stability for at least four cycles with only a slightly decreased yield. The high catalytic activity of Cu-doped CeO2 can be ascribed to the highly dispersed Cu species and abundant oxygen vacancies on their surfaces which activated the NHPI and O2 and promoted the adsorption/conversion of amine.
