Preparation of graphene/metal-organic composites and their adsorption performance for benzene and ethanol

Publication date: December 2015 Source:New Carbon Materials, Volume 30, Issue 6 Author(s): Guo-qiang Liu, Ming-xi Wan, Zheng-hong Huang, Fei-yu Kang 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.
