以1-氰甲基-3-甲基咪唑四氯化铁盐([MCNIm]+[FeCl4]-)为前体， SBA-15为模板，采用硬模板纳米浇筑法合成碳/碳化铁复合介孔材料.研究了合成温度和时间对所得材料比表面积的影响.利用氮气吸附-脱附、 X 射线衍射、透射电子显微镜及 X 射线光电子能谱等对材料进行表征.结果显示，在800℃下煅烧能够得到相对较大比表面积的材料，同时延长煅烧时间可以得到高比表面积、孔径分布均匀且结构较完整的材料，其最大比表面积可达517.96 m2/ g.此外，氢气吸附测试表明，此种材料具有一定的储氢性能.

Using 1-cyanomethyl-3-methylimidazolium tetrachloridoferrate( Ⅲ) as precursor and SBA-15 as template, the mesoporous iron carbide frameworks were synthesized by the hard template method, and the structure and morphology were characterized by X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy and N2 adsorption-desorption isotherms. The influences of the synthesis temperature and calcination time on the material surface area were also investigated. The results showed that mesoporous carbide with large specific surface area was obtained under 800 ℃. Moreover, uniform pore size distribution and complete structure and specific surface(517. 96 m2 / g) could be built with prolonging calcination time. Furthermore, hydrogen adsorption isotherm revealed that the material exhibited medium hydrogen storage capacity.
