Abstract

Novel graphene oxide–carbon nanotubes (GO–CNTs) hybrid aerogels were fabricated via a freeze-drying method using aqueous solutions of GO and CNTs. The resulting aerogels were characterized by scanning electron microscopy, X-ray diffraction, Fourier transformed infrared spectroscopy and thermal gravity analysis. The three-dimensional GO–CNTs aerogels were used to remove uranium(VI) from aqueous solutions. The results showed that GO–CNTs aerogels had high removal ability to uranium(VI) and could be a promising sorbent for many environment applications.
