炭-镍微晶复合材料的制备及对噻吩的吸附性能

Study on the fabrication of carbon-nickel microcrystalline composites and its adsorption of thiophene

以D001型苯乙烯系强酸性阳离子交换树脂为炭前驱体,经镍离子交换、炭化与CO2活化制备了炭-镍复合材料,热重分析与红外光谱结果表明离子交换树脂的磺酸基经高温炭化-活化处理后,发生了热解反应,并生成一定的耐热砜基,负载的金属主要为单质镍。制备的炭材料外观为均匀有光泽的黑色球形颗粒,主要为炭-镍单质微晶复合结构,以微孔为主,比表面积为343.23m2/g,对噻吩吸附能力可达13.20mg/g。

carbon-nickel microcrystalline composites were synthesized by cation exchange of type D001 cation exchange resin followed by carbonization and activation. Thermogravimetry and infrared spectrum analysis showed that the sulfonic group of cation exchange resin oceured pyrolysis and generated sulfonyl group followed by carbonization and activa- tion. The appearance of carbon materials was glossy black spherical particles, was made up of carbon-nickel microcrystalline composite structure,mainly for microporous, specific surface area and adsorption capacity of thiophene were 343. 23m2/g and 13.20mg/g,respectively.
