Iron nitride nanoparticles encapsulated in nitrogen‐doped carbon bulk is fabricated by a simple costep nitridation of Fe2O3 and carbonization of polyaniline. The microstructure and elemental composition of the materials are analyzed by transmission electron microscope, scanning electron microscope, X‐ray diffraction, and X‐ray photoelectron spectroscopy. The pore size distribution and specific surface area of the materials are identified using nitrogen adsorption and desorption method. The results illustrate that iron nitride nanoparticles with 5–20 nm in size are uniformly dispersed in the carbon bulk. The presence of carbon bulk effectively prevents the agglomeration of iron nitride nanoparticles, making the electrochemical performance of iron nitride nanoparticles/carbon nitride composite nanomaterials superior to that of pure iron nitride nanomaterials. At a current density of 0.5 A g−1, the specific capacitance (257.5 F g−1) of the iron nitride nanoparticles/nitrogen‐doped carbon bulk is much higher than that (119.5 F g−1) of pure iron nitride.

聚苯胺/ Fe2O3共混物中掺氮碳块中包埋的氮化铁纳米粒子及其电化学性能
通过对Fe 2 O 3进行简单的共步氮化来制备包裹在掺氮碳块中的氮化铁纳米颗粒和聚苯胺的碳化。通过透射电子显微镜，扫描电子显微镜，X射线衍射和X射线光电子能谱分析材料的微观结构和元素组成。使用氮气吸附和解吸方法确定材料的孔径分布和比表面积。结果表明，尺寸为5–20 nm的氮化铁纳米颗粒均匀分散在碳块中。碳本体的存在有效地防止了氮化铁纳米颗粒的团聚，使得氮化铁纳米颗粒/氮化碳复合纳米材料的电化学性能优于纯氮化铁纳米材料。在0.5 A g -1的电流密度下，比电容（257.5 F g-1）的氮化铁纳米颗粒/氮掺杂的碳堆积比（119.5 F G高得多-1纯氮化铁的）。
