Journal ArticleDOI
Two-dimensional transition metal carbides.
Michael Naguib,Olha Mashtalir,Joshua Carle,Volker Presser,Jun Lu,Lars Hultman,Yury Gogotsi,Michel W. Barsoum +7 more
TL;DR: Evidence is presented for the exfoliation of the following MAX phases by the simple immersion of their powders, at room temperature, in HF of varying concentrations for times varying between 10 and 72 h followed by sonication.
Journal ArticleDOI
Cation Intercalation and High Volumetric Capacitance of Two-Dimensional Titanium Carbide
Maria R. Lukatskaya,Olha Mashtalir,Chang E. Ren,Yohan Dall'Agnese,Patrick Rozier,Pierre-Louis Taberna,Michael Naguib,Patrice Simon,Patrice Simon,Michel W. Barsoum,Yury Gogotsi +10 more
TL;DR: This study demonstrates the spontaneous intercalation of cations from aqueous salt solutions between two-dimensional (2D) Ti3C2 MXene layers, and provides a basis for exploring a large family of 2D carbides and carbonitrides in electrochemical energy storage applications using single- and multivalent ions.
Journal ArticleDOI
Intercalation and delamination of layered carbides and carbonitrides
Olha Mashtalir,Michael Naguib,Vadym Mochalin,Yohan Dall'Agnese,Min Heon,Michel W. Barsoum,Yury Gogotsi +6 more
TL;DR: Intercalation of hydrazine, and its co-intercalation with N,N-dimethylformamide, resulted in increases of the c-lattice parameters of surface functionalized f-Ti3C2, from 19.5 to 25.48 and 26.8 Å, respectively.
Journal ArticleDOI
Amine-Assisted Delamination of Nb2C MXene for Li-Ion Energy Storage Devices
TL;DR: Freestanding, flexible paper is produced that exhibits high capacity and excellent stability when used as the electrode for Li-ion batteries and capacitors.
Journal ArticleDOI
One-step synthesis of nanocrystalline transition metal oxides on thin sheets of disordered graphitic carbon by oxidation of MXenes.
Michael Naguib,Olha Mashtalir,Maria R. Lukatskaya,Boris Dyatkin,Chuanfang (John) Zhang,Volker Presser,Yury Gogotsi,Michel W. Barsoum +7 more
TL;DR: It is shown that heating 2D Ti3C2 in air results in TiO2 nanocrystals enmeshed in thin sheets of disordered graphitic carbon structures that can handle extremely high cycling rates when tested as anodes in lithium ion batteries.
