Abstract:
Pristine and indium doped magnesium ferrite nanoparticles have been prepared by the sol-gel method. The phase formation has been confirmed from XRD (X-ray diffraction) whereas nanosize has been displayed through TEM (Transmission Electron Microscope) images. BET (Brunauer-Emmett-Teller) analysis showed an increase in surface area for the indium doped sample compared to pristine magnesium ferrite. The superparamagnetic nature of nanoparticles has been observed from M-H studies carried on VSM and these have been efficiently employed as a catalyst in organic transformation such as quinazolinone synthesis and Henry reaction. The indium doped magnesium ferrite catalyst has been found to be highly active and recyclable in nature. The high surface area and Lewis acidity govern their catalytic performance whereas magnetic nature makes the separation easier.
