preparation of (mwcnts)-cooh/ceo2hybrid as an efficient catalyst for claisen-schmidt condensation

Acid  functionalized  multi-walled  carbon  nanotubes/ceo2 (mwcnts)-cooh/ceo2 hybrid  was fabricated by the reaction of functionalized (mwcnts)-cooh and ce(no3)2.6h2o in acetic acid. 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).  the modification  of  mwcnts-cooh  with  ceo2  produced  an  efficient  catalyst  for  the  claisen–schmidt condensation, soa large variety of chalconeswere obtained in high yield using a catalytic amount of (mwcnts)-cooh/ceo2 hybrid (5 mol%).
