载镍碳分子筛的制备与性能研究

以间苯二酚一甲醛溶胶为碳前驱体，Ni（N03）z·6Hz0为金属源，PS为硬模板，F127为表面活性剂，碱性条件下由溶剂挥发诱导自组装合成碳分子筛。初步探索了镍加入量，炭化温度等合成条件对碳分子筛结构的影响，并制备了碳分子筛复合材料。采用XRD、N2吸/脱附、FTIR、TG等手段对材料进行表征。结果表明：金属镍已成功掺杂到碳分子筛复合材料中，所得材料微孔含量较高；在间苯二酚和甲醛摩尔比1：3，Ni（N03）2·6H20．1g，F1270．75g，PSl．5g，700℃碳化条件下所制备的碳分子筛比表面积为357．65rn2/g，总孔容可达到0．50417cm^3/g。

Study on the preparation and properties of carbon molecular sieve

Carbon molecular sieve（CMS） was obtained in alkaline atmosphere by solvent-evaporation - induced self- assembly using resorcinol formaldehyde （RF） polymer as carbon source, Ni（NO3 ） 2 . 6H20 as metal source, PS as template, F127 as surface active agent. The influence of synthetic con ditions such as the amount of nickel doping, carbonization temperature on the structure of carbon mo lecular sieve was investigated. Finally, carbon molecular sieve composites were prepared. The materi als were investigated with the measurements of X-ray diffraction, nitrogen sorption/desorption, Fourier transform infrared spectrometer, Thermo-gravimetric analysis and so on. The results show： Nickel has been successfully doped into the carbon molecular sieve composites and the material ob tained has high microporous levels;Under the condition of the molar ratio 1：3 of resorcin and formal dehyde, Ni（NO3）2 . 6H20 0. lg, F127 0. 75g,PS 1. 5g, 700℃ of carbonization temperature, the ob- tained material has a BET surface area of 357. 65 m2/g,a total pore volume of 0. 50417 cm^3/g.
