- W4282979866 abstract "The cobalt sulfide (Co 9 S 8 ) nanoparticles (NPs) have been synthesized by the solvothermal techniques by utilizing Cobalt diethyldithiocarbamate (Co[DTC] 2 ) as single-source precursor and hexadecylamine (HDA) as shape directing agent. As-prepared Co 9 S 8 NPs were characterized with structural, morphological, thermal, Spectroscopic and surface analysis using PXRD, TEM, SEM-EDS, TG/DTA, FTIR, Raman and XPS studies respectively. The electrochemical performances were investigated by galvanostatic charge-discharge (GCD), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS) analysis with Co 9 S 8 NPs modified working electrode. The Co 9 S 8 NPs modified electrode delivered excellent specific capacitances of 502 Fg −1 at current densities of 1 Ag −1 . The capacitance retention of Co 9 S 8 was found to be 87 % over the examination even after 7000 cycles. Furthermore, a hybrid supercapacitor (HSC) device assembled with cathode and anode materials delivers a high energy density of 15.47 Wh kg −1 with power density of 1274.9 W kg −1 . • Co 9 S 8 nanoparticles have been successfully synthesized by simple solvothermal reflex method. • PXRD and SEM exhibit the cubic crystalline structure and spherical-like morphology for Co 9 S 8 nanoparticles. • Co 9 S 8 electrode material exhibits Faradic pseudo capacitive behaviour. • An enhanced high specific capacitance of 502 Fg −1 and current density of 1 Ag −1 . • The Co 9 S 8 electrode material exhibits 87 % energy retention in cyclic test after 7000 cycles." @default.
