通过掺杂策略增强水热法制备的钡掺杂CoSnO3的电容特性

The pollution and energy crises are serious problems, there is an immediate desire for sustainable and affordable energy-storing technology. In this work, Ba-doped perovskite cobalt tin oxide (CoSnO 3 ) was produced via a hydrothermal procedure for usage as a supercapacitor charge storage medium. Physical and electrochemical characteristics of samples were studies through Brunauer Emmett Teller (BET) analysis, X-ray diffraction (XRD) technique, galvanostatic charge/discharge (GCD) and cyclic voltammetry (CV) study, respectively. Electrodes composed of Ba-doped CoSnO 3 demonstrated faradaic behavior, achieving a specific capacitance of 1006.21 F/g over current density (C d ) of 1 A/g in contrast the pure CoSnO 3 revealed a lower specific capacitance (471.52 F/g). The charge transfer resistance (R ct ) of Ba-doped CoSnO 3 measured at 0.65 Ω was derived from the Nyquist plot. CoSnO 3 encountered considerable challenges with elemental contamination, limiting its application as active electrode materials in supercapacitors because of insufficient cycling stabilities. A doping technique was established to deal with these drawbacks and a hydrothermal process was utilized to develop Ba-doped CoSnO 3 . Doping optimise the adsorption of OH − ions on the material interface, hence accelerating electrochemical properties. The improved electrochemical performance of Ba-doped CoSnO 3 revealed that it has potential to be utilized for supercpacitor applications.
