Abstract In order to explore new adsorbent materials, graphene oxide was prepared by modified Hummers oxidation method. Furthermore, graphene oxide was reduced by using glucose as the reducing agent and the cross-linking agent to connect graphene nanosheets, and SiO₂ nano-powder was added to construct graphene-nano-SiO₂ aerogels with the three-dimensional porous structure. The surface morphology and microstructure of graphene-nano-SiO₂ aerogels were observed and characterized by scanning electron microscopy and fully automatic surface analyzer. The adsorption characteristics of graphene-nano-SiO₂ aerogels on the volatile organic compound crotonaldehyde were studied. The results show that the three-dimensional porous structure of graphene-nano-SiO₂ aerogel provides a larger specific surface. The optimum addition amount of SiO₂ nano-powder in composite aerogel is 58.8%, and its adsorption value for crotonaldehyde was 127.1 mg/g.
