2020年2月24日 · This study demonstrates a potentially scalable, solvent free and phase selective synthesis of uncapped α-NiS, β-NiS and α-β-NiS composites using nickel alkyl (ethyl, octyl) xanthate...

NixSy in various crystal phases (NiS, NiS2, and Ni3S4) was synthesized on thermally reduced graphene oxide (TRGO) by a one-step hydrothermal process. Microstructures and morphologies of...

The XRD patterns of Te@NiS and SGCN/Te@NiS, show a minor shift towards the lower angles, demonstrating the effective doping of Te into NiS and the coupling of SGCN with Te@NiS...

2024年3月1日 · Nickel sulfide (NiS) electrode materials has emerged attention as a promising candidate due to its high value of specific capacitance and outstanding redox activities. This study includes synthesis, characterization, and study the electrochemical properties of the layer structured single-phase β-NiS electrode.

2013年10月1日 · The morphology, structure, and composition of the as-synthesized nanostructures have been confirmed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Optical properties of as-prepared sample were investigated by photoluminescence spectroscopy; the emission peak is at 555.04 nm and shows the blue shift.

2007年11月13日 · The results shown were correlated with factor group analysis, confirmed with X-ray diffraction (XRD), and compared with previous studies. These results provide a standard reference for the Raman spectra of Ni 3 S 2, important for studying the interactions between sulfur and nickel (or nickel-based alloys) in a sulfur-containing atmosphere.

In this work, three-dimensional hierarchically porous nanogranular NiS (NiS-3D-Nf) and wrinkle-shaped NiS (w-NiS-3D-Nf) structures were fabricated directly on nickel foam by a simple...

3 天之前 · XRD patterns of NiS electrodes are given in Fig. 2. NiS electrodes grown on cubic NiF (JCPDS: 98-005-3807) have a hexagonal crystal system (JCPDS: 01-074-7239). XRD peaks confirm the polycrystalline nature of NiS samples grown on NiF. With increasing deposition time, the peaks for the NiS-30 sample slightly shifted to the right and new peaks ...

Nickel acetate was used as a precursor to prepare pure NiS nanoparticle. Sodium sulphide and Sodium hydroxide is added to this solution. On calcinating the sample at 5000C and 10000C for 1 hour, β-NiS nanoparticle was obtained. The prepared sample has been characterized by powder XRD and UV-VIS Spectroscopy.
