2022年2月15日 · In this study, NiF 2 /porous carbon (NPC) nanocomposites were synthesized by confining a nickel precursor to porous carbon and performing heat treatment with ammonium fluoride (NH 4 F). The Ni precursor is converted to (NH 4) x NiF y via reactions with the decomposition products of NH 4 F at 100 °C, and then to NiF 2 at 200 °C.

2021年8月1日 · Transition metal fluorides nanoparticles were prepared by co-precipitation method. As-prepared materials were characterized by XRD, SEM, FTIR, TGA, DSC and CV studies. The electrochemical performances of NiF 2 NPs significantly improved up to 0.12 mAg −1 as compared to CoF 2 NPs and NH 4 MnF 3.

Nickel(II) fluoride is the chemical compound with the formula NiF 2. It is an ionic compound of nickel and fluorine and forms yellowish to green tetragonal crystals. Unlike many fluorides, NiF 2 is stable in air. Nickel(II) fluoride is also produced when nickel metal is exposed to fluorine.

2020年7月28日 · Superstructures or self-assembled nanoparticles open the development of new materials with improved and/or novel properties. Here, we present nickel fluoride (NiF 2) self-assemblies by successive preparatory methods.

2024年8月14日 · In this study, we introduce for the first time a novel nickel compound with two anions, displaying a high theoretical energy density—the Ni 4 OHF 7 nanomaterial. We provide a comprehensive analysis of its structure and its electrochemical performance in …
