Abstract :Dimeric disulphide Schiff bases were synthesized via reactions of 2-aminophenyl disulphide with various aromatic aldehydes under reflux and prepared nano ‐ sized cerium oxide as catalyst. It observed that, when nanocatalyst were used, the catalyst could be reduced the reaction time and increased yields compared with the none-catalyst conditions. Moreover, the CeO 2 nanocatalyst were easy preparation, non-hazardous, eco-friendliness and low cost. The morphological features of CeO 2 nanocatalyst were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), but also ligand structures were investigated some techniques such as fourier transform infrared (FT-IR), nuclear magnetic resonance (NMR) spectroscopy and thermogravimetric analysis (TGA) / differential thermal analysis (DTA).
