An amine-modified ZSM-5/SBA-16 (ZS) micro-/mesoporous composite was synthesized for CO₂ capture using nonionic tri-block copolymer pluronic (F127) as a template, tetraethyl orthosilicate (TEOS) as a silicon source and ZSM-5 zeolite as part of silicon aluminum source by embedding method. The amine-bifunctionalized samples were prepared by first grafting with aminepropyltriethoxysilane (APTES) and then impregnating with different concentrations of tetraethylenepentamine (TEPA). The amine efficiency, adsorption kinetics, thermal stability, regeneration performance and the effects of impregnated amine loadings (30–60%) and temperatures (30–90 °C) on the CO₂ adsorption performance were investigated using a thermal gravimetric analyzer (TGA) in the mixed gases (15 vol% CO₂ and the balance of N₂). The best adsorbent after modification of ZSM-5/SBA-16 composite material was screened to study CO₂ adsorption mechanism and adsorption kinetics. With the increase of the TEPA amount, the adsorption capacity of amine-bifunctionalized material first increased and then decreased. At 90 °C, the bifunctionalized ZSM-5/SBA-16 displayed the highest CO₂ adsorption performance of 1.630 mmol/g at the TEPA loading of 55%. The CO₂ adsorption mechanism of the bifunctionalized material was the synergistic effect of physical adsorption and chemical adsorption. After five adsorption/desorption cycle regenerations, the saturated adsorption capacity of the composite material was 1.496 mmol/g, which was only 8.2% lower than the original adsorption capacity. The composites exhibited good CO₂ adsorption performance, indicating the promising industrial applications for CO₂ capture form actual flue gas after desulfurization.

以非离子三嵌段共聚物普朗尼克 (F127) 为模板，原硅酸四乙酯 (TEOS) 为硅源，ZSM合成了胺改性的 ZSM-5/SBA-16 (ZS) 微孔/介孔复合材料用于 CO ₂捕获-5沸石作为硅铝源的一部分，采用嵌入法。通过首先用胺丙基三乙氧基硅烷 (APTES) 接枝，然后用不同浓度的四亚乙基五胺 (TEPA) 浸渍来制备胺双官能化样品。使用热重分析仪 (TGA) 研究了胺效率、吸附动力学、热稳定性、再生性能以及浸渍胺负载 (30–60%) 和温度 (30–90 °C) 对 CO ₂吸附性能的影响在混合气体中（15 vol% CO ₂和 N ₂的余额）。筛选出ZSM-5/SBA-16复合材料改性后的最佳吸附剂，研究CO ₂吸附机理和吸附动力学。随着TEPA用量的增加，胺双官能化材料的吸附量先增加后降低。在 90 °C 时，双功能化的 ZSM-5/SBA-16在 TEPA 负载量为 55% 时表现出最高的 CO ₂吸附性能，为 1.630 mmol/g。二氧化碳₂双功能化材料的吸附机理是物理吸附和化学吸附的协同作用。经过5次吸附/解吸循环再生后，复合材料的饱和吸附容量为1.496 mmol/g，仅比原来的吸附容量低8.2%。该复合材料表现出良好的CO ₂吸附性能，表明脱硫后从实际烟气中捕获CO _{2 的}工业应用前景广阔。
