Abstract

A series of carbon-mineral composites with the carbon content varying from 1.5 to 12.2 wt.% was synthesized by MgO carbonization in 1,3-butadiene at 600 oC. The synthesized carbon-mineral composites were studied by EPR, XRD and transmission electron microscopy. It was shown by EPR that the MgO surface was completely covered with carbon after depositing 8-10 wt.% C. MgO from the composite was dissolved by treatment in hydrochloric acid. The surface area of the carbon samples obtained after the acid treatment was studied by thermal desorption of argon. It was shown that the synthesized carbon material consisted of several graphene layers. Specific surface area of the synthesized graphene had a maximum about 1800-1900 m2/g for samples obtained from C-MgO composites containing 8-10 wt.% C.

模板法合成石墨烯

以1,3-丁二烯为原料，在600℃下用MgO炭化法制备了碳含量在1.5 ~ 12.2 wt.%的碳-矿物复合材料。采用EPR、XRD和透射电镜对合成的碳矿物复合材料进行了表征。EPR表明，沉积8-10 wt.% c后，MgO表面完全被碳覆盖，复合材料中的MgO在盐酸中溶解。采用氩气热解吸法对酸处理后碳样品的表面积进行了研究。结果表明，合成的碳材料由多层石墨烯组成。对于含有8-10 wt.% C的C- mgo复合材料样品，合成的石墨烯的比表面积最大约为1800-1900 m2/g。
