新型酚醛树脂软模板法制备微孔碳

Preparation of Microporous Carbon by New Phenolic Resin Soft Template Method

针对微孔碳的制作工艺复杂、成本较高的缺点,采用新型酚醛树脂软模板法试验制备了微孔碳,该方法工艺简单、成本较低,通过改变酚醛树脂的原料配比和搅拌方式来考察上述因素对微孔碳的形貌和孔径的影响。结果表明,当m(苯酚)∶m(甲醛溶液)∶m(H_2O)∶m(Na_2CO_3)为1∶6∶80∶0.010和m(葡萄糖酸)∶m(ZnCl_2)∶m(HCl)∶m(H_2O)为1∶2∶6∶20时,制备的微孔碳球直径在2～5μm,比表面积达670 m^2·g^(-1),平均孔径在0.37 nm。

In order to overcome the shortcomings of complex preparation process and high cost of microporous carbon,a new type of phenolic resin soft template method was used to prepare microporous carbon.This method is simple in process,low in cost and has high research value.The effects on the morphology and pore diameter of microporous carbon were investigated by changing the ratio of phenolic resin materials and the stirring method.The results showed that the microporous carbon sphere was 2-5μm in diameter,with a specific surface area of 670 m^2·g^-1 and an average pore diameter of 0.37 nm when m(phenol)∶m(formaldehyde solution)∶m(H 2O)∶m(Na 2CO 3)=1∶6∶80∶0.010 and m(gluconic acid)∶m(ZnCl 2)∶m(HCl)∶m(H 2O)=1∶2∶6∶20.
