Abstract
In recent decades, super capacitor is considered to be a prime candidate for the next generation of electrochemical applications. In the present work, nano structured pure Co2SnO4 nanoparticles (Co2SnO4 NPs) were successfully synthesized by a facile hydrothermal method using sodium hydroxide as a mineralizer. This synthesized product calcinated at 900 °C was used to the formation of cubic structured Co2SnO4 NPs, which is confirmed through TG/DT analysis. Crystalline phase and the mean crystalline size of the Co2SnO4 NPs were evaluated from the XRD study. Surface morphology of Co2SnO4 NPs was confirmed by FE-SEM and HRTEM analysis. Hydrodynamic size distribution and surface potential were measured by using dynamic light scattering. From the FT-IR study, the presences of Co–O and Sn–O vibrations were identified. Cyclic voltammetry measurement, the specific capacitance value was calculated as 596 F g−1 at a scan rate 2 mV s−1 for Co2SnO4 NPs which paves way for the super capacitor applications.
