Abstract
Recent progress of graphene research has triggered wide interest in 2D nanomaterials
and related porous nanocomposites other than carbons. Here we will firstly present
efficient exfoliation of graphene, aiming at the large-scale production of high-quality,
thin layers, solution-processable graphene sheet materials. We will further demonstrate
a bottom-up assembly approach to the fabrication of porous nanosandwiches based
on chemically derived graphene. Different graphene-based porous nanosheets such
as carbon, metal, metal oxide, and nanohybrides will be produced to possess the
intriguing features such as thin thickness, large aspect ratio, high monodispersity and
large surface area. Further, nanosandwiches based on graphene coupled with organic
porous materials will be produced. The porous features of such graphene/organic porous
materials can be tailored at the molecular level. Finally, 3D macroporous architectures
will be built up based on the assembly of graphene sheets and nanosandwiches. These
materials show hierarchical porous structures with high surface areas which can
facilitate the diffusion of guest ions or molecules in many electrochemical systems. As
the consequence, graphene-based 2D nanohybrid materials may hold great potential in
the areas of catalysis, sensors, supercapacitors and batteries.
