Application of (MWCNTs)-COOH/CeO₂ hybrid as an efficient catalyst for the synthesis of some nitrogen-containing organic compounds

ABSTRACT:

Modification of acid functionalized multi-walled carbon nanotubes (MWCNTs)-COOH with CeO₂ nanoparticles using Ce(NO₃)₂.6H₂O, produced an efficient catalyst for the synthesis of some nitrogen-containing heterocycles such as celecoxib. The products were identified by CHN analysis, NMR, and FT-IR spectra. On the other hand, synthesis of CeO₂ nanoparticles and their conjugation on the surface of (MWCNTs)-COOH have been confirmed by FT-IR, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and Energy-dispersive X-ray spectroscopy (EDX).
