摘要：

Hausmannite (Mn3O4) plate like nano-grains, coin like nano-sphere and nano-petals structure were respectively prepared employing co-precipitation, sol- gel and hydrothermal route. The obtained product was characterized comprehensively. High specific capacitance value of 462.70 F/g at 10 mV/s was achieved using hydrothermal method. The magnetic behavior of product both in ZFC and FC modes employing VSM study confirmed the paramagnetic behavior turned as ferrimagnetic while changed the mode from ZFC to FC. The product synthesized by hydrothermal method possessed the good coercivity value of about 1965 Oe at 5 K. The preparation protocols have dominant influence on structural, morphological, optical, electrochemical and magnetic properties of nanostructured materials.
