摘要

Cubic crystalline Mg2SnO4 nano particles (NPs) were prepared by the facile hydrothermal method and NaOH used as a mineralizer. The synthesized product was calcinated at different temperatures and sample calcinated at 900 degrees C was optimized by using XRD and TG/DT analysis. XRD result confirms that the Mg2SnO4 NPs has cubic phase with lattice space group of Fd3m with mean crystalline size of 26 nm. The sample calcinated at 900 degrees C was further characterized by FE-SEM with EDS, HR-TEM with SAED pattern, DLS and Cyclic Voltammetry. The effect of calcination temperature on the formation of Mg2SnO4 NPs as well as the particle size and crystalline structure were observed. The surface morphology of the sample indicates that the NPs were in irregular cubic shape and EDS analysis revealed the presence of the Mg, Sn, and O. Zeta potential depicts good stability of the sample and a specific capacitance value of 328 Fg(-1) was observed which suggests that Mg2SnO4 NPs could be a potential candidate for super capacitor applications.
