MWCNT decorated MnFe2O4 nanoparticles as an efficient photo-catalyst for phenol degradation

A MWCNT/MnFe2O4 nanocomposite was successfully synthesized by the hydrothermal method and its structural, optical, morphological and magnetic characterizations were done by XRD, FT-IR, TEM, SEM and VSM techniques. The nanocomposites have inverse spinel structure with a particle size of about 27-30 nm. Magnetic measurements reveal that all the MWCNTs/MnFe2O4 nanocomposites display ferromagnetic behavior at room temperature. The nanocomposites exhibit superior photo catalytic activity of phenol degradation compared to pure MnFe2O4, owing to the reduction of photo-induced electron-hole pair recombination induced by the introduction of MWCNTs.
