摘要
采用具有较高水热稳定性、较厚孔壁的介孔分子筛MTS-9为模板,合成一种新型的介孔碳分子筛:C-MTS-9,并通过X射线粉末衍射、热重分析、透射电镜和氮气吸附/脱附等方法对其进行表征.结果表明,C-MTS-9分子筛具有较高的BET比表面,孔径达到5 nm,且孔分布比较均一;电化学的循环伏安测量表明,C-MTS-9具有较好的电化学性质.
A new type of mesoporous carbon （ denoted as C-MTS-9） was synthesized with icate MTS-9 as template. The template MTS-9 prepared from zeolite ＂ seed solution＂ mesoporous titanosilhas some common structural characters including the thicker wall, the higher hydrothermal stability, disorder in some extent, zeolite-like connectivities in the wall. The mesoporous carbon sieve C-MTS-9 was investigated by XRD, TG, TEM, and N2 adsorption/desorption techniques. The characteristic results show that the mesoporous carbon sieve C-MTS-9 has larger BET surface areas than conventional CMK-3. In addition, the mesoporous carbon sieve C-MTS-9 exhibits narrower pore size distribution. In particular, the mesoporous carbon sieve C-MTS-9 shows interesting electrochemical double-layer capacitance （EDLC） behavior resulted from regular 3D interconnected mesopores.
