Abstract

Comparative studies of the characteristics of high-molecular organic matter (cotton lint), subjected to pyrolytic carbonization under conditions of high-intensity microwave radiation in various gaseous media (N2, CO2, Ar), have been carried out. The following methods were applied: determination of the adsorption activity by methylene blue indicator, X-ray fluorescence analysis, transmission electron microscopy with microanalysis, and X-ray phase analysis. Electrodes were fabricated from carbon materials obtained by microwave carbonization using different gases, and symmetric cells were assembled according to the two-electrode scheme. Their electrochemical properties were investigated using cyclic voltammetry and galvanostatic charge–discharge methods. The materials obtained using a CO2 gaseous medium were found to possess the best characteristics.

纤维素微波热解炭化过程中不同气体介质对所得活性炭性能的影响
对高分子有机物(棉絮)在不同气体介质(N2、CO2、Ar)的高强度微波辐射条件下的热解碳化特性进行了对比研究。采用亚甲蓝指示剂测定吸附活性、x射线荧光分析、透射电镜微量分析和x射线相分析。用不同气体微波碳化得到的碳材料制备电极,并按双电极方案组装对称电池。采用循环伏安法和恒流充放电法对其电化学性能进行了研究。用CO2气体介质获得的材料具有最好的特性。
