摘要

摘要: 采用溶剂热法制备了金属有机骨架-氧化石墨烯(MOF/GO)复合材料,通过氮吸附/脱附、红外光谱对其比表面积和孔结构、表面官能团进行了表征,考察了其吸附苯和乙醇的性能。结果表明,当氧化石墨烯的添加量为5.25 wt%时,复合材料的比表面积和孔容最大。该材料对苯和乙醇有很高的吸附容量,其最大吸附容量可分别达到72 和 77 cm³/g。MOF-5/GO复合材料吸附挥发性有机物(VOCs)的容量不仅受孔结构的影响,其表面特性也对吸附性能有重要作用。氧化石墨烯含量为3.5 wt%的GO/MOF复合材料对乙醇的吸附容量显著增强是由于其含有大量的含氧官能团。

Abstract: Graphene/metal-organic composites were synthesized by a solvothermal method and characterized by nitrogen adsorption, SEM and IR and their adsorption properties for benzene and ethanol were investigated. It was found that the surface area and pore volume both have maximum values for a graphene oxide (GO) percentage of 5.25 wt%. The composites have high adsorption capacities for both benzene and ethanol, and the maximum uptakes reach 72 and 77 cm³/g, respectively. The adsorption capacities of volatile organic compounds are determined by both the pore structure and the surface properties. The maximum ethanol adsorption capacity for the composite with a GO percentage of 3.5 wt% is due to its abundant oxygen-containing functional groups.
