“…From 145 °C to 220 °C, around 1.45 % weight loss of the precursor relates to the removal of the absorbed water. The total weight loss of the precursor is about 27.21 % from 220 °C to 280 °C, which is chiefly ascribed to the transformation of NH 4 MnF 3 to MnF 2 , NH 3 and HF, The reaction equation as follows: NH 4 MnF 3 →MnF 2 +NH 3 ↑+HF↑ . The XPS is applied to confirm the component of Mn element, as displayed in Figure b.…”

Porous MnF2 hollow spheroids are synthesized by using a facile solvothermal method. As‐synthesized MnF2 exhibits excellent electrochemical properties. The high reversible capabilities of 0.533 Ah/g at 0.057 A/g and 0.453 Ah/g at 0.577 A/g are obtained after 150 cycles for lithium‐ion batteries. Furthermore, the same MnF2 displays a high reversible specific capacity of 0.199 Ah/g at 2.308 A/g. As to sodium‐ion batteries, an initial reversible capability of 0.41 Ah/g at 0.01 A/g can be acquired and 0.154 Ah/g at 0.05 A/g can be retained after 150 cycles. It is noteworthy that as‐synthesized MnF2 could be a promising anode material in both sodium‐ and lithium‐ion batteries.

“…surfaces showed that low friction can be obtained for the commensurate layers, both under low normal load and high normal load. Likewise, the literature presents a comprehensive account of theoretical and experimental studies into the structural, microstructural, electronic, interface, thermodynamic, and magnetic properties of various types of nitride-based materials [47][48][49][50].…”

CrN, one of the most investigated transition metal nitrides, is noted for its wear, corrosion, and oxidation resistance. It also has many other unique chemical and mechanical properties. In the present study, we conducted a density functional theory (DFT) analysis to probe the structural, electronic, and optical properties of pristine and Mo-doped CrN structures in non-crystalline phases using different combinations in which one or two Cr and/or N atoms were substituted by Mo. This study found that the Cr 4 Mo 2 N 2 structure was chemically and energetically the most stable species among the six considered clusters (

Herein, CoF 2 was synthesized by a solvothermal method. The characterization results of the phase and morphology of the sample show that it was successfully synthesized and its morphology is composed of micron particles with uneven size and shape. The electrochemical test results of SCs in different electrolytes show that CoF 2 has electrochemical activity only in alkaline electrolytes. Notably, the electrochemical behavior of CoF 2 in LiOH solution is different from that in other alkaline solutions in that charge-discharge curve has a quasi-isosceles triangle shape and the CV curve has no obvious redox peak. That is, it has pseudocapacitance behavior in LiOH. Furthermore, CoF 2 as catalyst for HER requires an overpotential of only 168 mV to obtain current density of 10 mA cm À 2 and a Tafel slope of 116 mV dec À 1 in 1 M KOH solution. This research provides a novel way to explore excellent performance electrode materials for SC and HER.
