We disclosed the redox properties of CeO 2 in organic reactions at low temperature of 303 K. CeO 2 works as the most effective heterogeneous catalyst for imine formation from benzyl alcohol and aniline at 303 K among various metal oxides and showed more than 38‐fold higher activity than other simple metal oxides. CeO 2 is applicable to the reaction of various alcohols and amines and gives high yields (80–98 %) and high selectivities (89–>99 %). Kinetic measurements, MS, and FTIR analyses demonstrated that the high activity of CeO 2 is a result of reactive oxygen species at the redox sites on CeO 2 . This discovery can help to create a new field in metal oxide catalysis.
