Facile hydrothermally synthesized mesoporous manganous stannate (Mn2SnO4) nanoparticles and its electrochemical properties

Cubic spinel phase mesoporous Mn2SnO4 nanoparticles (NPs) were successfully prepared by a facile hydrothermal method. The formations of Mn2SnO4 NPs were characterized by thermo gravimetric/differential thermal (TG/DT) analysis. The understanding of TG/DT analysis prepared NPs were calcinated at different temperature and investigated through x-ray diffraction (XRD) patterns. XRD analysis confirms the Mn2SnO4 NPs has spinel cubic phase and evaluated mean crystalline size similar to 30 nm. The calcinated sample at 850 degrees C was optimized and chosen for the further investigations. The surface morphology of Mn2SnO4 NPs was analyzed by field emission-scanning electron microscope (FE-SEM) and high resolution-transmission electron microscope (HR-TEM) analysis which indicates Mn2SnO4 NPs were in nearly spherical shaped. Energy dispersive spectroscopy (EDS) analysis revealed the presence of Mn, Sn and O elements. The stability of the Mn2SnO4 NPs analyzed through dynamic light scattering (DLS) measurements which shows good stability. The surface area of the Mn2SnO4 NPs similar to 38.747 m(2) g(-1) measured through Brunauer-Emmett-Teller (BET) method. In the present investigation, cyclic voltammetry (CV) measurements exhibits superior specific capacitance value 540 Fg(-1) at a scan rate of 2 mV s(-1) from the result, Mn2SnO4 NPs could be a potential and novel electrode material for super capacitance applications.
