Several mesostructured cellular foams (MCFs) were prepared and modified for NO adsorption. TMB, NH₄F and n-heptane were used as swelling agents, and APTES was used as the modified agent. The morphological structure, chemical composition, thermostability were tested to study the effects of the preparation process on the characterizations of materials. NO adsorption ability of the materials were studied and discussed. NH₄F and n-heptane had better pore swelling effects compared to TMB, however adding TMB together with NH₄F and n-heptane could not enlarge the pore structure further. The MCFs materials could keep steady below 800 °C, but after grafting APTES on the surface of the materials, the thermogravimetric curve of materials began to decrease at 300 °C. The materials using NH₄F and n-heptane as the swelling agents, and modified by APTES had better NO adsorption ability, and the selectivity of the materials were decided by the molecular polarity of the adsorbates. After the modification, the hydrophobic effect of the samples could increase because of the alkyl groups in APTES. The adsorption capacity of the materials could keep steady for ten times without the coexisting component, H₂O, CO₂ and SO₂ all had negative effects on the regeneration of the materials.

制备了几种介孔泡沫（MCFs）并进行了NO吸附改性。将TMB，NH ₄ F和正庚烷用作膨胀剂，将APTES用作改性剂。测试了形态结构，化学组成，热稳定性，以研究制备过程对材料表征的影响。对材料的NO吸附能力进行了研究和讨论。与TMB相比，NH ₄ F和正庚烷具有更好的孔溶胀效果，但是与NH ₄ F和正庚烷一起加入TMB不能进一步扩大孔结构。MCFs材料可以稳定在800以下 °C，但将APTES接枝到材料表面后，材料的热重曲线在300  °C时开始下降。以NH ₄ F和正庚烷为溶胀剂并经APTES改性的材料具有较好的NO吸附能力，材料的选择性由被吸附物的分子极性决定。改性后，由于APTES中的烷基，样品的疏水作用会增强。在不存在共存成分的情况下，材料的吸附能力可以保持十倍稳定，H ₂ O，CO ₂和SO ₂均对材料的再生没有负面影响。
