摘要

这项工作展示了通过在450°C的氮气流下对普鲁士蓝(PB)/氧化石墨烯杂化物进行一步热处理，制备纳米多孔碳化铁-氧化铁/还原性氧化石墨烯(IC-IO/ rGO)杂化物。通过静电相互作用将PB纳米颗粒原位沉积在氧化石墨烯薄片上，初步制备了PB/GO杂化物。形貌分析表明，IC-IO纳米颗粒在氧化石墨烯纳米片上均匀覆盖，碳(C)、氧(O)和铁(Fe)在氧化石墨烯纳米片上均匀分布。由于杂化的组成和控制的形貌，得到的IC-IO/rGO杂化物的表面积(~40 m2/g)比煅烧的氧化石墨烯片和PB纳米颗粒(不含氧化石墨烯)的表面积显著增强。

Fabrication and Characterization of Prussian Blue-Derived Iron Carbide-Iron Oxide Hybrid on Reduced Graphene Oxide Nanosheets

This work demonstrates the fabrication of a nanoporous iron carbide-iron oxide/reduced graphene oxide (IC-IO/ rGO) hybrid via a controlled one-step thermal treatment of Prussian blue (PB)/GO hybrid at 450 °C under N2 flow. The PB/GO hybrid is initially prepared through the in-situ deposition of PB nanoparticles on the GO sheets through electrostatic interactions. The morphological analysis of the hybrid reveals the uniform coverage of the rGO sheets by IC-IO nanoparticles and the even distribution of carbon (C), oxygen (O), and iron (Fe) on the rGO nanosheets. As a result of the hybrid composition and controlled morphology, the surface area of the obtained IC-IO/rGO hybrid (~40 m2/g) is significantly enhanced compared to those of the calcined GO sheets and PB nanoparticles (without GO).
