摘要:

以生物质糖蜜为原料, K2CO3为活化剂制备了糖蜜基多孔炭. K2CO3的使用改善了传统活化剂KOH对设备腐蚀的问题, 避免了传统活化剂ZnCl2可能引发的致毒性. 分析了活化条件对产率的影响. 采用扫描电子显微镜(SEM)、 X射线衍射(XRD)、 N2吸附-脱附分析(BET)和傅里叶变换红外光谱(FTIR)表征了糖蜜基多孔炭, 结果表明其为石墨化层堆结构, 表面富含羟基、 羧基、 酯基或醚基等官能团, 具有丰富的孔结构, 比表面积可达1219 m2/g, 并证实了800 ℃为最佳的活化温度. 电化学测试结果表明, 糖蜜基多孔炭具有优良的双电层储能性能.

Abstract:

A facile method for the synthesis of porous carbon from molasses with K2CO3 as the activator(KPCs) was present. Effects of different conditions on the yield of KPCs were analyzed. The samples were characterized with scanning electron microscopy(SEM), X-ray diffraction(XRD), N2 adsorption-desorption analysis and Fourier transform infrared spectroscopy(FTIR). The results show that the KPCs have graphitized layer stack structure, and have surface functional groups of hydroxyl, carboxyl, ester and ether group. Also, the KPCs have porous structure and their specific surface area is up to 1219 m2/g. The optimized activation temperature was 800 ℃. The porous carbon based molasses will be an ideal electric double layer capacitors material in the field of energy storage.
