▎ 摘　　要

Graphene aerogel is a three-dimensional macroscopic material assembled from two-dimensional graphene sheets. Due to its high porosity , large specific surface area and low density , it has a broad application prospect in the adsorption and removal of water pollutants and has become a research hotspot. However, most of the related researches focused on bulk graphene aerogels, and few researches on graphene-based aerogel beads. This review summarizes the preparation methods of graphene-based aerogel beads, including electrostatic spray, electrostatic spinning , microfluidic technology and wet spinning. Taking the wet spinning method as the representative , the influencing factors for aerogel beads formation are analyzed, such as the concentration and viscosity of GO dispersion, extrusion parameters, the type and concentration of coagulation bath, etc. Furthermore , the factors of adjusting the pore size of the material are further analyzed. For example, the pore size of the material can be adjusted within a certain range by controlling the GO concentration, the GO layer sizes, and the temperature of freezing treatment. In view of the different treatment objects in the wastewater, the design of graphene-based aerogel beads with excellent adsorption performance, recycling performance and controllable micromorphology and the optimization and innovation of preparation methods are still the key points of exploration in future.
