Thermal and electrochemical analysis on SnSO3/ZnSO3 nanocomposite

SnSO3/ZnSO3 nanocomposite is synthesized by hydrothermal method. X-ray powder diffraction assures perfect formation of nanocomposite. It reveals morphology of nail like nanorod structure. Thermal analysis illustrates the sample’s thermal behavior. X-ray photoemission analysis describes the chemical state of Zn, Sn, S and O inSnSO3/ZnSO3. Electrochemical study in three electrode system, exhibits voltammogramof bell-shaped curve. Operational potential window is 1.6 V. Chronopotentiometry depicts the quasi-triangular curves, demonstrating pseudocapacitor behavior. Specific capacitances at 1 A/g current density is 117.8 F/g. Nyquist plot for SnSO3/ZnSO3 assures pseudocapacitor behavior and suggests that the system is found to be stable.
