  Abstract:

  Graphene, a one-atom-thick two-dimensional (2D) carbon material, has attracted increasing attention in the past several years due to its high surface area, remarkable thermal conductivity, excellent electronic conductivity and mechanical properties. Different from most porous carbon materials, the surface area of graphene depends on its solid surface, but not the porosity. However, graphene sheets tend to form irreversible agglomerates or even restack to form graphite due to their strong p–p stacking and van der Waals interactions between the intersheet of graphene, resulting in a dramatic decrease of the surface area.

  In order to make full utilization of the high intrinsic surface area of graphene, recently, porous graphene materials including graphene nanomesh, crumpled graphene and graphene foam, have attracted tremendous attention and research interest, owing to their exceptional porous structure (high surface area, and high pore volume) in combination with the inherent properties of graphene, such as high electronic conductivity, good thermal stability, and excellent mechanical strength. Interestingly, porous graphene materials and their derivatives have been explored in a wide range of applications in the fields of electronic and photonic devices, energy storage, gas separation/storage, oil absorption and sensors.
