The impact of different surfactants on the structure, surface area, and electrochemical properties of hydrothermally synthesized spinel NiCo2O4 nanoparticles

NiCo 2 O 4 Nanoparticles have been synthesized by a facile hydrothermal method followed by annealing at a temperature decided based on differential thermal (DTA). Different additives and surfactants were used in preparation under the same synthesis conditions and their effects on the physical proper...

Description
Summary:NiCo 2 O 4 Nanoparticles have been synthesized by a facile hydrothermal method followed by annealing at a temperature decided based on differential thermal (DTA). Different additives and surfactants were used in preparation under the same synthesis conditions and their effects on the physical properties of spinel nickel cobaltite nanoparticles have been investigated in a fair comparison study. The synthesis products have been characterized by using DTA and TGA measurements, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and Fourier transform infrared spectroscopy. Modification on the synthesis of the spinel nanoparticles provided high specific capacitance of 2253 F g −1 at 1 A g −1 and long-term cyclic stability for 10,000 cycles with 90% capacitance retention.
