摘要
以钴基多孔骨架(FJU-29)为模板,调控其炭化温度构建三例含钴氮的多孔碳(Co-N-C500、Co-N-C700和Co-N-C900)。通过PXRD、FTIR和SEM初步表征材料的结构及形貌,表明700℃为最佳炭化温度,Co-N-C700中Co的特征吸收峰最强,且表现出明显的磁吸现象。亚甲基蓝(MB)溶液吸附实验证明Co-N-C700具有最佳的吸附容量为47.8mg/g,且对MB的去除率可达100%,吸附行为符合准二级动力学模型。
Three porous carbon materials containing cobalt and nitrogen elements(Co-N-C500,Co-N-C700 and Co-N-C900)were prepared by controlling the carbonization temperature based on FJU-29 and characterized by PXRD,FTIR and SEM.The results showed that the best carbonization temperature was 700℃ and the absorption peak of which is the strongest for Co,accompanying with the obvious magnetic attraction.Methylene blue(MB)as a model dye was employed to assess them adsorption performance.Co-N-C700 exhibited excellent adsorption performance for MB with a high adsorption capacity of 47.8 mg/g and the removal rate of 100%.Meanwhile,its adsorption behavior was following the quasi-secondary kinetic model.
