In conclusion, a new type of CoFe2O4 magnetic nanocatalyst
has been developed with average sizes in the range 40–50 nm
using a combined sonochemical and co-precipitation process. The
resulting nanocrystals, as well as its dispersion exhibit excellent
stability in ethanol or aqueous solvent and can be stored with-
out any stabilizer for months. Agglomeration of the uncapped
nanoparticles was not observed during storage. The as-synthesized
nanoparticles showed high values of coercivity, saturation magne-
tization and squareness ratio. These MNPs were used as efficient
quasi-homogenous catalyst for Knoevenagel condensation reaction
of several aldehydes with ethylcyanoacetate in mild conditions.
Catalyst could be recovered from the reaction mixture by compart-
mentation with the aid of an external magnet and could be re-used
four times without significant loss in activity.
