Herein, we report a catalytic method for the one‐pot synthesis of imines from benzyl alcohols using air. The Ceria (CeO 2 ) nanoparticles were supported on (HT, TiO 2 , SiO 2 , Al 2 O 3 ) synthesised by Co‐precipitation in alcohol/water mixed solvents. The best catalytic activity was obtained with CeO 2 /HT for the oxidation of benzyl alcohols. CeO 2 /HT was investigated for oxidation and imines of various benzyl alcohols. Higher yield and a better reusability were observed under mild condition with air as oxidants.
