以二茂铁和四氯乙烯作为反应物,采用热解法在600℃反应10h得到一种高产率的剪纸状的碳片.扫描电镜的结果表明,剪纸状碳材料的厚度为20～40nm,宽度为100～200nm.通过氮气吸附-脱附等温曲线计算出产物的比表面积高达1 209m2/g,孔径分布在0.58～1.2nm之间.一系列对比实验表明,合成剪纸状碳材料的最佳条件为:0.093g二茂铁,反应温度为600℃,反应时间为10h.通过调整二茂铁与四氯乙烯的比例,可控制产物的形貌从剪纸状转化为空心球.剪纸状碳对于苯酚的吸附性能(82%)要远高于对罗丹明B的吸附性能(48%),并对其给出了可能的解释.
Using ferrocene and tetrachlorethylene as reactants, pyrolysis method was used to react at 600 ℃ for 10h to obtain a high yield of paper-cut carbon chips.The results of scanning electron microscopy showed that the thickness of paper-cut carbon materials was 20 ~ 40nm, Width of 100 ~ 200nm.According to nitrogen adsorption-desorption isotherm curve calculated product specific surface area up to 1 209m2 / g, pore size distribution between 0.58 ~ 1.2nm.A series of comparative experiments show that the best synthesis of paper-cut carbon materials The conditions are as follows: 0.093g ferrocene, reaction temperature 600 ℃, reaction time 10h. By adjusting the ratio of ferrocene to tetrachlorethylene, the morphology of the product can be controlled from paper-cut to hollow sphere. Adsorption of phenol (82%) is much higher than that of rhodamine B (48%) and gives a possible explanation.
