不同结构中孔炭材料的制备和热稳定性研究

摘要

利用溶剂挥发自组装的方法制备了2种不同孔结构中孔炭材料。低温N2吸脱附、SAXS、HRSEM和TEM测试表明,所制备的材料分别具有柱状结构和墨水瓶状的中孔结构。考察了不同炭化温度对2种结构中孔炭的影响,结果表明柱状结构的中孔炭材料具有较好的热稳定性。%In this manuscript, two kinds of mesoporous carbons （MCs） with different pore structures were prepared by soft-templating method. The microstructue of MCs was studied by high resolution transmission electron microscope, nitrogen adsorption-desorption isotherms and small angle X-ray scattering. Results showed that MCs with cylinder pore structure had the better thermal stability than that of MCs with ink-bottle like pore structure.
