Abstract

Bu çalışmada, MnCo2S4 nanoteller 3D-nikel köpük üzerinde hidrotermal yöntemle iki aşama da sentezlendi ve süperkapasitör elektrot malzemesi olarak araştırıldı. MnCo2S4 nanotellerinin kristal yapısı ve morfoloji analizleri yapıldı. Elektrokimyasal ölçümler 1 M potasyum hidroksit sulu elektrolit çözeltisi yapıldı. 0.5 A g−1 akım yoğunluğunda alınan GCD ölçümünden elde edilen spesifik kapasitans değeri 450 F g−1'dir. Ayrıca, numune 3000 şarj-deşarj döngüsünden sonra başlangıçtaki spesifik kapasitansın % 46'sını koruyarak iyi bir döngü kararlılığı gösterdi.

Two-step synthesis of MnCo2S4 nanowires for supercapacitor electrode

Abstract

In this study, MnCo2S4 nanowires were synthesized on 3D-Ni foam by the hydrothermal process in two-step and investigated as supercapacitor electrode material. Crystal structure and morphology analyzes of MnCo2S4 nanowires were performed. Electrochemical measurements were taken in 1 M of a potassium hydroxide aqueous electrolyte solution. The specific capacitance value calculated from GCD measurement taken at a current density of 0.5 A g−1 from the sample was 450 F g−1. Furthermore, the sample have good cycling stability by keeping 46% of the initial specific capacitance after 3000 cycles.
