Journal ArticleDOI
Improved Synthesis of Graphene Oxide
Daniela C. Marcano,Dmitry V. Kosynkin,Jacob M. Berlin,Alexander Sinitskii,Zhengzong Sun,Alexander S. Slesarev,Lawrence B. Alemany,Wei Lu,James M. Tour +8 more
TL;DR: An improved method for the preparation of graphene oxide (GO) is described, finding that excluding the NaNO(3), increasing the amount of KMnO(4), and performing the reaction in a 9:1 mixture of H(2)SO(4)/H(3)PO(4) improves the efficiency of the oxidation process.
Journal ArticleDOI
Longitudinal unzipping of carbon nanotubes to form graphene nanoribbons
Dmitry V. Kosynkin,Amanda L. Higginbotham,Alexander Sinitskii,Jay R. Lomeda,Ayrat M. Dimiev,B. Katherine Price,James M. Tour +6 more
TL;DR: A simple solution-based oxidative process for producing a nearly 100% yield of nanoribbon structures by lengthwise cutting and unravelling of multiwalled carbon nanotube (MWCNT) side walls is described.
Journal ArticleDOI
Effect of Synthesis on Quality, Electronic Properties and Environmental Stability of Individual Monolayer Ti3C2 MXene Flakes
Alexey Lipatov,Mohamed Alhabeb,Maria R. Lukatskaya,Alex Boson,Yury Gogotsi,Alexander Sinitskii +5 more
TL;DR: In this article, a modified synthetic method is reported for producing high-quality monolayer 2D transition metal carbide Ti3C2Tx flakes, and their electronic properties are measured.
Journal ArticleDOI
Spontaneous high-concentration dispersions and liquid crystals of graphene
Natnael Behabtu,Jay R. Lomeda,Micah J. Green,Amanda L. Higginbotham,Alexander Sinitskii,Dmitry V. Kosynkin,Dmitri E. Tsentalovich,A. Nicholas G. Parra-Vasquez,Judith Schmidt,Ellina Kesselman,Yachin Cohen,Yeshayahu Talmon,James M. Tour,James M. Tour,Matteo Pasquali +14 more
TL;DR: It is shown that graphite spontaneously exfoliates into single-layer graphene in chlorosulphonic acid, and dissolves at isotropic concentrations as high as approximately 2 mg ml(-1), which is an order of magnitude higher than previously reported values.
Journal ArticleDOI
Lower-Defect Graphene Oxide Nanoribbons from Multiwalled Carbon Nanotubes
TL;DR: The new, optimized method, which introduces a second, weaker acid into the system, improves the selectivity of the oxidative unzipping presumably by in situ protection of the vicinal diols formed on the basal plane of graphene during the oxidation, and thereby prevents their overoxidation and subsequent hole generation.
