2020年3月24日 · We report an optimized chemical vapor transport method, which allows growing FeP single crystals up to 500 mg in mass and 80 mm3 in volume. The high quality of the crystals obtained by this method was confirmed by means of EDX, high-resolution TEM, low-temperature single crystal XRD and neutron diffraction experiments.

2021年11月15日 · The FeP, N-Carbon HNSs, Fe, P, N-Carbon HNSs exhibited a better ORR performance than the FeP, N-Carbon HNSs, owing to their unique nanostructure and favorable chemical components that exposed more active sites. The findings provide insights into the controlled synthesis of transition-metal-heteroatom-codoped carbon nanomaterials for the ...

Fe2P and FeP are thermodynamically stable at the Earth’s inner core pressures and 0 K according to the obtained results, whereas Fe3P stabilizes with respect to decomposition to Fe + Fe2P at ...

设计合成了一种多壳层中空多孔结构的磷化铁 (FeP)微球, 通过扫描电子显微镜 (SEM)、 透射电子显微镜 (TEM)、 X射线衍射 (XRD)和X射线光电子能谱 (XPS)对微球的表面形貌和物相组成等进行表征, 并通过电化学工作站测试了材料的析氢性能. 结果表明, FeP微球和掺杂导电剂碳纳米管...

2025年3月5日 · In view of the impurity of P-poor Fe 2 P phase in FP x CT materials, the molar ratio of P to Fe is increased so as to achieve high-capacity FeP phase in the final products of FeP@C/Ti 3 C 2 materials (FPCT-460). The XRD patterns of FPCT-460 and FPC-460 without Ti 3 C 2 Mxene demonstrate that the crystal size of FeP in FPCT-460 materials is ...
