ABSTRACT
Graphene, a two-dimensional single-layer sheet of sp2-hybridized conjugated carbon lattice, has attracted intense interest for its potential in various applications such as hydrogen storage, carbon capture, and electrode material in electrochemical energy devices. Graphene oxide sheets generally prepared by the chemical exfoliation of graphite, possessing various reactive functional groups such as hydroxyl, epoxy, and carboxylic groups, are a vital building block to fabricate functional porous materials. Graphene-based porous materials have been prepared by various methods such as the cross-linking method, in situ reduction method, chemical activation, and template-directing method. The as-prepared graphene-based porous materials show improved or excellent performance in various elds. In this chapter, we will summarize the preparation of graphene-based porous materials, and their applications in the adsorption of gas and organic dyes. Furthermore, graphene-based porous materials can be scaled up for practical application in the future due to their facile preparation, low cost, and excellent adsorption performance.
