| Sumario: | In recent years, graphene-based aerogels (GAs) have been extensively studied owing to the excellent characteristics of low density, high specific surface area and porous structure, which show great potential in many applications. The disadvantages of traditional bulk graphene-based aerogels, for instance, strong device-dependence, large size and poor scalable production, limit their practical application and development. Meanwhile, conventional preparation techniques ignore the requirements of materials shape and size for specific application scenarios. As a new aerogels display form with novel structure, graphene-based aerogel microspheres (GAMs) not only have various advantages of GAs but possess properties of flexible and controllable size and scalable production, which tremendously enrich the application scenarios of GAMs.The fabrication methods and structure of GAMs, as well as the application fields of water pollution treatment, electromagnetic wave absorption and electrocatalysis were elaborated in this review.Meanwhile, the internal mechanism of GAS during molding assembly process was also pointed out. |
