Abstract: | "Water vapor often present in the atmosphere will influence the adsorption of volatile organic compounds (VOCs). The competitive adsorption behavior of toluene and water vapor on synthesized zeolitic imidazolate framework-8 (ZIF-8) and graphene oxide (GO) hybrid composites was investigated in a humid atmosphere. The ZIF-8/GO composites were successfully prepared in a methanol system at room temperature and exhibited tunable nanoscale morphology and surface area, both determined by the GO content. A series of characterization techniques confirmed the formation of strong interactions between ZIF-8 and GO in the synthesized composites. Adsorption experiments demonstrated that the ZIF-8/GO composites with a GO content of 4 wt% had the highest toluene adsorption capacity of 116 mg g(-1) at a relative humidity (RH) of 55%, increased by 19% compared with pristine ZIF-8, and the recyclability of the adsorbent was investigated. The results showed that the synthesized ZIF-8/GO composites exhibited a higher toluene uptake capacity than pristine ZIF-8 crystals even at relatively high humidity, indicating that the ZIF-8/GO composites could be effective adsorbents in a humid atmosphere" |
