摘要

In order to develop efficient and environment benign sorbents for water purification, a simple hydrothermal process for fabrication of the halloysite (HNTs)/graphene oxide (GO) composite aerogels comprising HNTs anchored on graphene oxide sheets was developed. The morphology and structure of the materials were characterized by scanning electron microscopy (SEM), nitrogen adsorption-desorption, and Fourier transform infrared (FT-IR). The results demonstrated that the composites exhibit large surface area (S-BET = 361.3778m(2)g(-1)) and high pore volume (V-p = 1.2432cm(3)g(-1)) with only 10wt% of HNTs, higher than that of the ture GO aerogel (S-BET = 142.8816m(2)g(-1), V-p = 0.6106cm(3)g(-1)). The adsorption properties of the pure GO aerogels and n-HNTs/GO composite aerogels with 10wt% of n-HNTs were measured using a UV-Vis spectrophotometer. The results reflected that the adsorptivity of MB by the n-HNTs/GO composite aerogels was 99.3%, much higher than the pure GO aerogels (89.4%).
