Hydrothermally Synthesized CoSn(OH)6 Nanoparticles for Electrochemical Performance

Abstract

Cubic phase CoSn(OH)₆ nanoparticles were successfully synthesized by a facile hydrothermal method using NaOH as a mineralizer. The prepared sample was analyzed by using X-ray diffraction (XRD) and the analysis confirmed that the CoSn(OH)₆ nanoparticles have a spinel cubic structure with lattice space group Pn3m and mean crystalline size of 25 nm. Field emission scanning electron microscope (FE -SEM) study showed that the cubic with polyhedral shaped surface morphology of the CoSn(OH)₆ nanoparticles was seen. The specific capacitance value of 450 Fg^-1 was calculated at the scan rate of 2 mVs^-1 as measured by using cyclic voltammetry. In the present investigation, the prepared CoSn(OH)₆ nanoparticles are suggested as a potential candidate for supercapacitor applications.
