Abstract The porous organic polymers (POPs) and its carbonized materials are having excellent textural properties with promising applications towards gas adsorption. The melamine based porous organic polymer is synthesized by one-pot condensation reaction and the porous carbon materials are prepared by carbonization with/without activator at 700 °C. The porous structure of the materials is confirmed by SEM and HR-TEM analysis. The prepared porous polymer is used to study the gas (CO2, CH4, N2) uptake application. The polymer exhibits considerable CO2 uptake and good selectivity. The monolayer adsorption of CO2 and heterogeneous surface of the polymer are studied by the Langmuir and Freundlich isotherms. Thermodynamic parameters (ΔG0, ΔH0 and ΔS0) of the adsorption process confirm the spontaneity, physisorption nature and randomness of the process. Qst values also confirm physisorption process. The porous carbonized materials have a high surface area, microporous surface area and total pore volume.

用于 CO2 吸收研究和碳化材料制备的富氮多胺多孔网络

摘要 多孔有机聚合物（POPs）及其碳化材料具有优异的结构特性，在气体吸附方面具有广阔的应用前景。三聚氰胺基多孔有机聚合物是通过一锅缩合反应合成的，多孔碳材料是通过在700℃下有/无活化剂碳化制备的。通过SEM和HR-TEM分析证实了材料的多孔结构。制备的多孔聚合物用于研究气体（CO2、CH4、N2）吸收应用。该聚合物表现出可观的 CO2 吸收和良好的选择性。通过 Langmuir 和 Freundlich 等温线研究 CO2 的单层吸附和聚合物的异质表面。吸附过程的热力学参数（ΔG0、ΔH0 和 ΔS0）证实了该过程的自发性、物理吸附性质和随机性。Qst 值也证实了物理吸附过程。多孔碳化材料具有高表面积、微孔表面积和总孔容。
