以凌霄花瓣为生物模板、蔗糖为炭源、氯化钠为造孔剂、氢氧化钾为活化剂,采用生物诱导法合成了分级多孔炭,确定了最佳工艺参数并研究了各工艺参数对该多孔炭显微结构及吸附性能的影响.结果表明：最佳合成工艺参数为蔗糖、NaCl、KOH 溶液质量分数分别为1．0％,2．0％,1．0％,体积比为1∶1∶1,活化温度为650℃,活化时间为60 min；制备的多孔炭基本保留了凌霄花瓣的微观形貌,孔径分布较窄,比表面积高达357 m2.g－1；该多孔炭具有极强的吸附能力,在120 mg.L－1的亚甲基蓝溶液中,在120 min时达到吸附饱和,吸附量可达60 mg.g－1.
With campsis grandiflora as bio-template,sucrose as carbon source,NaCl as pore-forming agent and KOH as activator,hierarchical porous carbon was prepared by biological induced method.The optimum process parameters were determined and the effects of different process parameters on the microstructures and adsorption properties of the porous carbon were investigated.The results show that the optimum synthesis process parameters were obtained as follows:1.0wt% sucrose solution,2.0wt% NaCl solution and 1.0wt% KOH solution with volume ratio of 1∶1∶1;activation temperature of 650 ℃;activation time of 60 min.The obtained porous carbon retained the microstructure of campsis grandiflora and had a relatively narrow pore size distribution and a relatively high specific surface area of 357 m2.g-1 .The adsorption property of the porous carbon was excellent.In the methylene blue solution of 120 mg.L-1 ,the porous carbon reached the adsorption saturation at 120 min with the adsorption capacity of 60 mg.g-1 .
