一步法由离子液体制备多孔含氮碳材料

The Synthesis of Nitrogen-cantain Porous Carbon Material from the Ionic Liquid via one Step Methed

以1-氰甲基-3-丁基咪唑二三氟甲磺酰亚胺盐为前体,采用一步法直接煅烧得到高含氮量的多孔含氮碳材料.通过氮气吸脱附、X射线衍射、透射电镜、元素分析及X射线光电子能谱分析对材料进行表征.研究发现,在800℃温度下煅烧1 h所得到的材料不但具有较高的比表面积(543.9210 m2/g),而且含氮量高达13.94%.

A template - free synthesis of high nitrogen contain porous carbon material using ionic liquid （1- cyanomethyl- 3 -butylimidazolium bis （trifluoromethylsulfonyl） imide ） as carbon precursors was discussed. This material was characterized by nitrogen adsorption -desorption, X -ray diffraction （XRD） , transmission electron microscopy（ TEM ）, elemental analysis and X -Ray photoelectron spectroscopy（XPS）. The results show that after calcined at 800℃ hour the resulting material not only has a high surface area （543. 9210 m2/g） , but also has a high nitrogen content of up to 13.94%.
