离子液体制备氮掺杂石墨化炭纳米囊及其CO2捕获性能
Synthesis of nitrogen-doped graphitic carbon nanocapsules from a poly( ionic liquid) for CO2 capture
摘要
Abstract
A poly(ionic liquid) was prepared from an ionic liquid monomer that was obtained by the reaction of 1-vinylimid-azole, 4-vinyl-benzene chloride with 2,6-di-tert-butyl-4-methylphenol. The poly(ionic liquid) was mixed with K3[Fe(CN)6] and a 5 nm silica colloidal sol, carbonized at 900℃ for 4 h, and sequentially treated with HNO3 and NaOH to remove the iron and silica to obtain nitrogen-doped graphitic carbon nanocapsules. The iron and silica acted as a graphitization catalyst and template, respec-tively. The nitrogen-doped graphitic carbon nanocapsules have a diameter of 50 nm and a wall thickness of 6 nm and have a high ad-sorption capacity and good recyclability for CO2 capture. The addition of SiO2 nanoparticles in the synthesis significantly increased the specific surface area from 100. 4 to 865. 7 m2·g-1 and the CO2 adsorption capacity from 0. 76 to 2. 14 mmol·g-1 .关键词
