A graphitic nanoribbons (GNRs) encapsulated with Fe nanoparticles (NPs) hybrids derived from pyrrole and FeCl₃ through polymerization, freeze drying and catalytic graphitization process showed excellent capacitive and cycle performance using as pseudo-capacitive material for supercapacitors (SC). The precursor of FeCl₃ ingeniously served as oxidant for polymerization of pyrrole, catalyst for graphitization of polypyrrole and pseudo-capacitive material for SC successively. The obtained Fe@GNRs electrode exhibited a remarkable pseudocapacitance performance with a high specific capacitance of 526.7 F g⁻¹ at a discharge current density of 1 A g⁻¹. GNRs obtained by catalytic graphitization of polypyrrole under metallic Fe could effectively protect and stabilize the encapsulated Fe NPs showing ~100% capacitance retention rate after 10,000 cycles under 10 A g⁻¹.

通过聚合、冷冻干燥和催化石墨化过程，用衍生自吡咯和 FeCl _{3 的}Fe 纳米粒子 (NPs) 杂化包封的石墨纳米带 (GNRs)显示出优异的电容和循环性能，用作超级电容器 (SC) 的赝电容材料。FeCl ₃的前驱体巧妙地先后作为吡咯聚合的氧化剂、聚吡咯石墨化的催化剂和SC的赝电容材料。获得的Fe@GNRs电极表现出显着的赝电容性能，在1 A g ^{- 1}的放电电流密度下具有526.7 F g ^{- 1}的高比电容. 通过聚吡咯在金属 Fe 下催化石墨化获得的 GNR 可以有效地保护和稳定封装的 Fe NPs，在 10 A g ^{- 1}下 10,000 次循环后显示 ~100% 的电容保持率。
