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 CeO₂ nanocatalyst were easy
preparation, non-hazardous, eco-friendliness and low cost. The morphological features
of CeO₂ 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).
