This review attempts to illustrate the different alternatives in the field of 2D materials (single-layers) from graphene to alternative inorganic materials such as metal chalcogenides, oxides, hydroxides, and metal–organic frameworks.

This Review discusses the interesting mechanism of field emission for N-doped CNTs and electronic structures of N-doped GNRs.

The band gap expansion of graphene ribbon has been clarified as arising from the undercoordination-induced bond contraction and quantum entrapment.

Simultaneous production of graphene flakes and carbon nanotubes in arc discharge, followed by the effective magnetic separation and deposition at different surfaces is demonstrated by splitting the high-temperature growth and low-temperature separation zones of the discharge using a non-uniform magnetic field and custom-designed catalyst.

Polyelectrolyte and carbon nanotube multilayer films are prepared from ionic liquid solutions, demonstrating the potential of ionic liquids as a non-aqueous working solvent for layer-by-layer assembly.

A simple method of fabricating few-layer and single-layer graphene which could be used for production on a gram scale is described.

We report a novel nanolithography technique for self-aligned polymer patterning on metallic nanowires and graphene ribbons. We show that by dissolution of polymers through localized heating, nanoscale trench structures can be fabricated to selectively expose the underlying conductive material, providing potential use for site-specific modification or functionalization of nanostructure devices.

In this paper, a novel method for the preparation of a nanostructured polyaniline/graphene hybrid material was developed. In addition to its thin, uniformity and flexible merits, it also shows excellent electrochemical performances than pristine individuals for supercapacitors.

Covalent functionalization of the graphene oxide with ferrocene on solid phase alumina results in intercalation and exfoliation of graphene oxide to single-layer ferrocene–graphene oxide.

We examine the SERS excitation profile for graphene with Au nanoparticles attached by means of chemical reduction. A charge-transfer resonance is observed at 2.09 eV.

We demonstrate the use of large-sized CVD grown graphene films configured as field-effect transistors for real-time biomolecular sensing.

Sequence-specific detection of DNA targets by combining molecular beacons with graphene oxide.

A facile chemical procedure capable of aligning CuO nanoparticles on graphene oxide in a water–isopropanol system is described.

We observe rotational misorientation in 2, 4 and 6 layers of suspended graphene sheets, which gives Moiré patterns in the HRTEM.

Graphene oxide in a mixture of DMAc and water can be easily reduced to graphene by simply heating it.

The electronic structure and the persistent current of zigzag hexagonal graphene rings are studied, determined by the even or odd quality of the ring width, which may be experimentally observable.

Herein, we report the fabrication of hydrogen gas sensors based on noble nanometal decorated one dimensional multi walled carbon nanotubes and two dimensional graphene by a simple drop casting technique.
