Covalently interconnected three-dimensional (3D) scaffolds of nanomaterials have received much attention of late, and carbon nanotubes (CNTs), graphene, graphene oxide (GO) etc. are some of such materials that could be interconnected to produce 3D structures. These nanoengineered 3D architectures could have high and tunable surface area, porous structure and interesting electron transport and mechanical properties and several applications related to electrical, mechanical, electrochemical, sensor and bio-medical could be explored using these structures.  Even though there are some recent efforts to build covalent junctions between nanotubular structures of CNTs, graphene and GO, the creation of three-dimensionally engineered nanoporous architectures via covalently interconnected nanoscale building blocks remains one of the fundamental challenges in nanotechnology. Another popular approach is the creation of covalent junctions between CNTs and graphene. In most reported works, additive elements such as boron, sulphur are used to create the interconnections and hence the 3D nanostructured architecture. Here, we shall discuss the synthesis of highly porous and covalently interconnected 3D-CNT framework without additive elements. Combination of excellent physical and chemical properties of such 3D porous architecture will be discussed here.
