Coal gangue causes a series of environmental problems due to its low utilization rate and high amount of hoarding. However, the preparation of porous materials with coal gangue is an effective method of resource utilization. Mesoporous silica and meso-microporous ZSM-5 were prepared with alkali melting activation-acid leaching and hydrothermal synthesis, respectively. The orthogonal experiment was used to explore the optimal preparation conditions for mesoporous silica. Meso-microporous ZSM-5 were characterized with instruments. The adsorption and desorption performance of the porous material was explored by dynamic adsorption/desorption on volatile organic compounds (VOCs).

利用煤矸石制备对 VOCs 具有优异吸附脱附性能的高硅多孔材料

煤矸石因利用率低、囤积量大而引发一系列环境问题。然而，利用煤矸石制备多孔材料是一种有效的资源化利用方法。分别采用碱熔活化-酸浸和水热合成制备介孔二氧化硅和介孔微孔ZSM-5。通过正交实验探索了介孔二氧化硅的最佳制备条件。用仪器对中微孔 ZSM-5 进行了表征。通过对挥发性有机化合物（VOCs）的动态吸附/解吸研究了多孔材料的吸附和解吸性能。
