In this report, NiCo₂S₄ nanoparticles (NPs) are successfully synthesized by a simple cost effective one step hydrothermal method using dissimilar sulfur sources (thiourea- NTU, thioacetamide- NTA) separately. The influence of sulfur source on structure, morphological, surface area and electrochemical performance are examined carefully. The X-Ray Diffraction Pattern of both samples displays the cubic phase of spinel NiCo₂S₄ crystal structures. TEM studies reveal Uniform Spherical (19–21nm) and spheroidal (22–23nm) shaped NPs. XPS spectra of both sample conforms the coexistence of Ni³⁺ and Ni²⁺ valence states of spinel cubic NiCo₂S₄. The surface area of NTA- NiCo₂S₄ found superior (91.23 m² g⁻¹) than NTU- NiCo₂S₄ (43.12 m² g⁻¹)_. The Electrochemical performance of NTA based NiCo₂S₄/Ni foam electrode results in showing high specific capacity values of 1051.49 C g⁻¹ (292 m A h g⁻¹) compare with NTU- NiCo₂S₄ (690 C g⁻¹/191 m A h g⁻¹) at a current density of 2 A g⁻¹ moreover, NTA- NiCo₂S₄ holds exceptional Capacity retention of 98 % after 10,000 GCD cycles at current density of 6 A g⁻¹ with excellent energy density of 88.377 W h Kg⁻¹ with power density of 2179.15 W kg⁻¹.The admirable electrochemical performance of NTA- NiCo₂S₄ brings out potential anticipation in supercapacitor applications.
