TLDR
The protocol allows the wet chemical synthesis of graphene from a new form of graphene oxide that consists of an intact hexagonal σ-framework of C-atoms that can be easily reduced to graphene that is no longer dominated by defects.Abstract:
A suitable technology for the preparation of graphene based on versatile wet chemistry is presented for the first time. The protocol allows the wet chemical synthesis of graphene from a new form of graphene oxide that consists of an intact hexagonal σ-framework of C-atoms. Thus, it can be easily reduced to graphene that is no longer dominated by defects.read more

Mechanism of graphene oxide formation.
Ayrat M. Dimiev,James M. Tour +1 more
TL;DR: This work shows that formation of GO from graphite constitutes three distinct independent steps, and that the reaction can be stopped at each step, and the corresponding intermediate products can be isolated, characterized, and stored under appropriate conditions.

High-quality graphene via microwave reduction of solution-exfoliated graphene oxide
Damien Voiry,Jieun Yang,Jacob Kupferberg,Raymond Fullon,Calvin Lee,Hu Young Jeong,Hyeon Suk Shin,Manish Chhowalla +7 more
TL;DR: A simple, rapid method to reduce GO into pristine graphene using 1- to 2-second pulses of microwaves is reported using microwave-reduced GO (MW- rGO) as the channel material and into particularly high activity for MW-rGO catalyst support toward oxygen evolution reactions.

Electric Field Effect in Atomically Thin Carbon Films
Kostya S. Novoselov,Andre K. Geim,Sergey V. Morozov,Da Jiang,Y. Zhang,S. V. Dubonos,Irina V. Grigorieva,A. A. Firsov +7 more
TL;DR: Monocrystalline graphitic films are found to be a two-dimensional semimetal with a tiny overlap between valence and conductance bands and they exhibit a strong ambipolar electric field effect.
Journal ArticleDOI
The rise of graphene
TL;DR: Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments.
