Graphene-based materials with aerogel structures were developed in recent years for various adsorption applications. In the present study, a hydrothermal process was developed to prepare graphene aerogel by using graphene oxide as a precursor, and the obtained aerogel was employed as a template for the growth of carbon nanotubes (CNTs). Various techniques were employed to study the morphology, surface property and composition of aerogel samples. The results showed that CNTs were in-situ grown on the sheet of graphene aerogel, endowing the material a hierarchical structure with enhanced surface area and meso- and micro-scale pores. These improved properties made the hybrid aerogel a superior material for the selective adsorption of a variety of organics and oils from water.
Graphical abstractA hybrid aerogel consisting of carbon nanotubes (CNTs) and graphene was prepared. The growth of CNTs on the graphene sheets in the hybrid aerogel endowed the material a hierarchical structure with low density, excellent hydrophobicity and oleophilicity to the organic compounds. The aerogel can adsorb a variety of oily liquids with outstanding reusability.Download high-res image (203KB)Download full-size image
