A series of micro-mesoporous structure ZSM-5/MCM-41 composites with different mesopore sizes were successfully fabricated through surfactant-mediated recrystallization method using the template agents with different alkyl chain length. Mesopore pore sizes were tuned from 2.11 nm to 5.09 nm. Taking ethyl acetate as the VOC probe molecule, the adsorption and desorption properties were evaluated by the dynamic adsorption breakthrough curves and TPD experiments. Results showed that the adsorption capacity was enhanced under dry and humid condition owing to the introduction of mesopore size structure. Especially for ZSM-5/MCM-41 (C12), its adsorption capacity reached up to 208.92 mg·g⁻¹ and 82.29 mg·g⁻¹ at dry and saturated humidity (4 v/v% H₂O). Simultaneously, the hierarchical molecular sieves exhibited an excellent regeneration performance. Even after the fifth cycle, above 86% adsorption capacity remained under humid condition. Moreover, the adsorption kinetics of ethyl acetate on ZSM-5/MCM-41 composites followed the Bangham model. The results indicated that hierarchical composite molecular sieve can be considered as a potential adsorbent for VOCs removal.

采用不同烷基链长度的模板剂，通过表面活性剂介导的重结晶方法，成功制备了一系列具有不同介孔尺寸的微介孔结构ZSM-5/MCM-41复合材料。中孔孔径从 2.11 nm 调整至 5.09 nm。以乙酸乙酯为VOC探针分子，通过动态吸附突破曲线和TPD实验评价其吸附和解吸性能。结果表明，由于介孔尺寸结构的引入，在干燥和潮湿条件下吸附能力均得到增强。尤其是ZSM-5/MCM-41(C12)，在干燥饱和湿度(4 v/v% H ₂ O)下，其吸附容量分别达到208.92 mg·g ^-1和82.29 mg·g ^{-1 。}同时，分级分子筛表现出优异的再生性能。即使在第五次循环后，在潮湿条件下仍保持86%以上的吸附能力。此外，ZSM-5/MCM-41复合材料上乙酸乙酯的吸附动力学遵循Bangham模型。结果表明，分级复合分子筛可作为去除VOCs的潜在吸附剂。
