使用前体碳化物衍生的碳（CDC）通过涉及石墨氧化和微波还原的大规模湿化学合成路线生产微/中孔还原氧化石墨（MMRGO）纳米片，所述前体碳化物衍生的碳（CDC）在1200摄氏度的高温下生产。X射线衍射（XRD）和透射电子显微镜（TEM）分析表明，MMRGO纳米片具有2-3层结构和波纹状形貌。N-2吸附等温线证实了CDC的RGO样品中微孔/介孔共存。在锂离子电池的阳极应用中，该RGO样品在0.1C倍率和1C倍率下具有增强的容量性能，在第100次循环时分别与1200 mAh g（-1）相似，在第200次循环时与1000 mAh g（-1）相似。皇冠版权所有（C）2015由爱思唯尔有限公司出版。保留所有权利。
Micro/meso-porous reduced graphite oxide (MMRGO) nanosheets were produced using precursor carbide-derived carbon (CDC), which was produced at a high temperature of 1200 degrees C, through a massive wet chemistry synthetic route involving graphite oxidation and microwave reduction. X-ray diffraction (XRD) and transmission electron microscopy (TEM) show that the MMRGO nanosheets were fabricated with 2-3 layers and ripple-like corrugations. N-2 sorption isotherms confirmed that micro/meso-pores coexisted in the RGO sample from CDC. In the anode application of Li-ion batteries, this RGO sample had an enhanced capacity performance at the 0.1 C rate and 1 C rate, with similar to 1200 mAh g(-1) at the 100th cycle and similar to 1000 mAh g(-1) at the 200th cycle, respectively.
