Abstract High-performance energy storage electrode materials are emerging demand in near future for the construction of supercapacitor with high energy and power densities. Herein, Nickel (II) Diethyldithiocarbamate was used as single source precursor for Nickel Sulfide (Ni9S8) two dimensional (2D) nanosheets preparation and hexadecylamine as shape directing agent via simple solvothermal method. The orthorhombic structure of Ni9S8 nanosheets was confirmed by X-ray diffraction (XRD) pattern. Scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM) images revealed that as-prepared Ni9S8 nanoparticles possess sheet-like morphology. Besides, the thermal stability of Ni(DTC)2 complex was studied by Thermo-gravimetric/Derivative thermo gravimetric(TG/DTG) with Differential scanning calorimetric (DSC) analysis. The electrochemical properties of Ni9S8 nanosheets was studied using galvanostatic charge-discharge (GCD) and cyclic voltammetry (CV) techniques. From the charge-discharge study of Ni9S8 nanosheets, a high specific capacitance of 281 Fg− 1 was obtained at a current density of 1 Ag− 1, and up to 82 % retentivity was achieved after 5000 cycles. Thus, the prepared Ni9S8 nanosheets could be one of the attractive potential active electrode materials for the application of supercapacitor.

We report on the synthesis, MS, UV-vis, NMR, HPLC and electrochemical characterization of magnesium sulfanyl porphyrazine with 2-[2-(4-nitrophenoxy)ethoxy]ethylsulfanyl substituents in the periphery. The electrochemical properties of novel macrocycle were studied by cyclic voltammetry and differential pulse voltammetry in non-aqueous electrolyte. The experimental data indicated the occurrence of clearly defined four redox couples corresponded to one-electron reactions of the [Formula: see text]-conjugated porphyrazine ring and substituents in the periphery. Multiwalled carbon nanotube/sulfanyl porphyrazine hybrids deposited on a glassy carbon electrode allowed for the evaluation of the effect of nitro peripheral groups on the electrochemical properties. The electrochemical behavior of immobilized nitro porphyrazine was consistent with the reduction mechanism for the various arylnitro compounds in aqueous media, with two processes characteristic of the redox transitions of the arylnitro group to the corresponding arylhydroxylamine and/or arylhydroxylamine–arylnitroso groups.
