氮掺杂多孔超交联聚合物的二氧化碳吸附性能研究
Study on CO2 adsorption performances of nitrogen-doped porous hypercrosslinked polymers
摘要
Abstract
With the increasingly severe problem of global warming,carbon dioxide(CO2)capture technology based on solid porous adsorption materials has received widespread attention as an important carbon emission reduction strategy.A series of nitrogen-doped porous hypercrosslinked polymers(HCPs)were prepared using benzimidazole(BMZ),carbazole(CBZ),diphenyl imidazole(DMZ)and azobenzene(ABZ)as reaction monomers.Characterization methods including SEM,N2 adsorption/desorption,elemental analysis and FT-IR were employed to analyze the influence of different monomer structures on the microstructure and pore structure of the HCPs.Static adsorption,dynamic adsorption and cyclic stability tests were carried out to evaluate their CO2 adsorption performance.The results show that the HCPs exhibit a fibrous microstructure with tightly arranged pore structures on the fibers.The smaller the size of the reaction monomer,the larger the specific surface area and micropore area of the prepared HCPs.Among them,the specific surface area of HCP-ABZ reaches 875.5 m2/g.The HCPs demonstrate excellent CO2 adsorption performance.The static CO2 adsorption capacity of HCP-CBZ at 273 K reaches 4.30 mmol/g,and the saturation adsorption capacity of HCP-BMZ during the dynamic CO2 adsorption process reaches 1.13 mmol/g.After five adsorption/desorption cycles,the CO2 adsorption capacity of HCP-BMZ remains basically unchanged,indicating excellent cyclic stability.The study provides a reference for the development of efficient CO2 adsorption materials.关键词
