改性葡萄糖基炭材料的CO_(2)吸附性能研究

Study on CO_(2)Adsorption Performance of Modified Glucose-based Carbon Material

多孔材料因具有孔隙结构丰富、表面特性易改善等优点,在CO_(2)捕集方面展示出广阔的应用前景。本文以葡萄糖和尿素为原料,采用水热炭化和KOH活化法制备掺氮炭材料,并对其进行TEPA浸渍改性,考察其对CO_(2)的吸附性能。研究结果表明:氮改性和TEPA改性都可以提升炭材料的CO_(2)吸附性能。

Porous materials show broad application prospects in CO_(2) capture because of their abundant pore structure and easy improvement of surface properties.In this paper,a nitrogen-doped carbon material was prepared by hydrothermal carbonization and KOH activation with glucose and urea as raw materials.And the carbon material was modified by TEPA,and their adsorption performance for CO_(2) were investigated.The results show that both nitrogen and TEPA modification can improve the CO_(2) adsorption capacity of carbon materials.
