Abstract
Nanoparticles (NP) of MnFe2 O 4 were synthesized via sol-gel method, with calcination process at 600 °C. The effects of different surfactants namely polypropylene glycol (PPG) and polysorbate 80 (PS80) in the formation of crystal structure, magnetic properties, and optical properties were studied using X-ray diffraction (XRD), vibration sample magnetometry, UV-visible diffuse reflectance spectroscopy (DRS), and photoluminescence (PL) spectroscopy. Brunauer-Emmett-Teller (BET) surface area test was also performed. XRD investigations revealed that MnFe2 O 4 sample synthesized using PS80 as surfactant (sample 2) showed pure crystalline phase of a cubic spinel structure whereas sample synthesized with PPG (sample 1) exhibited an additional phase of α-Fe2 O 3. The morphology of the samples was recorded using a scanning electron microscope (SEM). Energy dispersive X-ray (EDX) results showed that the composition of the elements was as relevant as expected from the sol-gel method. The magnetic hysteresis loops confirmed the super-paramagnetic behavior of both the samples. PL studies revealed a sharp narrow band green emission exhibited by both the samples. Catalytic activity of MnFe2 O 4 nanoparticles (NPs) was performed. The catalysts MnFe2 O 4, samples 1 and 2, were tested for the oxidation of benzyl alcohol to benzaldehyde. The conversion of benzyl alcohol reached a maximum of 82.45 % for MnFe2 O 4 sample 2, whereas for sample 1, the conversion was only 68.52 %. These Mn ferrite samples have potential applications in LED or laser diodes.
