Abstract

The synthesis of porous carbon materials was carried out by mechanochemical dehydrochlorination of polyvinyl chloride in the presence of alkalis (KOH, LiOH) using a high-energy planetary mill and the subsequent two-stage heat treatment of the obtained polyvinylenes (polymers with a conjugated double bond system)—carbonization to 400°C and carbon dioxide at 850°C or alkaline activation and 800°C, respectively. The structure of the obtained products was studied by Raman spectroscopy and transmission electron microscopy, analysis of isotherms of low-temperature adsorption/desorption of nitrogen. The resulting products are (micro-, meso-) porous amorphous carbon materials with specific surface S_BET from 460 to 605 m²/g, micropore volume from 0.09 to 0.21 cm³/g, and mesopore volume from 0.09 to 0.6 cm³/g

碱存在下聚氯乙烯的机械活化在多孔碳材料合成中的应用

摘要

多孔碳材料的合成是使用高能行星磨在碱（KOH，LiOH）存在下，通过对聚氯乙烯进行机械化学脱氯化氢，然后对得到的聚亚乙烯（具有共轭双键的聚合物）进行两阶段热处理键合系统）-分别在850°C或碱活化和800°C碳化至400°C和二氧化碳。通过拉曼光谱和透射电子显微镜研究了所得产物的结构，分析了氮的低温吸附/解吸的等温线。生成的产品是（微，中观）多孔无定形碳材料，比表面积S _BET为460至605 m ² / g，微孔体积为0.09至0.21 cm ³/ g，中孔体积从0.09到0.6 cm ³ / g
