A novel reduced graphene oxide‐montmorillonite three‐dimensional composite aerogel (rGO‐MMT aerogel) was synthesized successfully. The rGO‐MMT aerogel with good adsorption and recyclable property due to special 3D interconnection porous structure and good mechanical strength. The preparation process was carried out in aqueous solution under atmosphere pressure without any toxic agents or special instruments, which is a facile, green, and low‐cost method. The aerogel was characterized by X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FT‐IR), Transmission electron microscopy (TEM), Brunner‐Emmet‐Teller (BET) and X‐ray photoelectron spectroscopy (XPS). The adsorptive capacity and recycling of the aerogel were studied, including remove organic dyes (such as Methyl orange and Methylene blue) from wastewater and cycled five runs. The adsorption equilibrium data, adsorption process, and thermodynamic parameters were investigated. Moreover, the rGO‐MMT aerogel absorbent could be easily and directly separated with tweezers. The rGO‐MMT aerogel may find important environmental applications.
