Abstract

Nanoporous solids with high accessible specific surface area and pore volume, high chemical and mechanical stability are considered as one of the key materials to solve many energy and environment-related problems. Abundant porous carbon materials have attracted great attention in hydrogen/methane storage, and carbon capture. Graphene-based materials are relatively new members of the carbon family and opened up great scope for molecular sorption, storage and separation due to the flexibility in designing functionalized surfaces and tuneable porosities. In this chapter, we describe recent research efforts to synthesize a variety of graphene-based structures, starting with layered, expanded graphite, intercalation, exfoliation, chemical reduction, pillaring layers, self-assembly, surface functionalization, doping, metal dispersion, porous template, chemical activation, and hierarchical pore structures for hydrogen/methane storage and carbon capture.
