Conductive two-dimensional titanium carbide ‘clay’ with high volumetric capacitance
TL;DR: This capacitance report reports a method of producing two-dimensional titanium carbide ‘clay’ using a solution of lithium fluoride and hydrochloric acid that offers a much faster route to film production as well as the avoidance of handling hazardous concentrated hydrofluoric acid.
Journal ArticleDOI
NMR reveals the surface functionalisation of Ti3C2 MXene
Michael A. Hope,Alexander C. Forse,Kent J. Griffith,Maria R. Lukatskaya,Michael Ghidiu,Yury Gogotsi,Clare P. Grey +6 more
TL;DR: The internal surface terminations of Ti3C2Tx MXene are identified and quantified and there are found to be significantly fewer -OH terminations than -F and -O, with the proportions highly dependent on the synthesis method.
Journal ArticleDOI
Highly Conductive Optical Quality Solution-Processed Films of 2D Titanium Carbide
Andrew D. Dillon,Michael Ghidiu,Alex Krick,Justin Griggs,Steven J. May,Yury Gogotsi,Michel W. Barsoum,Aaron T. Fafarman +7 more
TL;DR: In this paper, it is shown that 2D Ti3C2 can be assembled from aqueous solutions into optical quality, nanometer thin films that, at 6500 S cm−1, surpass the conductivity of other solution-processed 2D materials, while simultaneously transmitting >97% of visible light per-nanometer thickness.
Journal ArticleDOI
Ion-Exchange and Cation Solvation Reactions in Ti3C2 MXene
Michael Ghidiu,Joseph Halim,Joseph Halim,Sankalp Kota,David L. Bish,Yury Gogotsi,Michel W. Barsoum +6 more
TL;DR: In this article, the authors investigated the effects of the presence of LiCl during the chemical etching of the MAX phase Ti3AlC2 into MXene Ti3C2Tx (T stands for surface termination) and found that the resulting MXene has Li+ cations in the interlayer space.
Journal ArticleDOI
Synthesis and characterization of two-dimensional Nb4C3 (MXene)
Michael Ghidiu,Michael Naguib,Chenyang Shi,Olha Mashtalir,L. M. Pan,B. Zhang,Jian Yang,Jian Yang,Yury Gogotsi,Simon J. L. Billinge,Simon J. L. Billinge,Michael Barsoum +11 more
TL;DR: The structure of this, only second MXene with formula M4X3, was investigated with pair distribution function analysis, and the resistivity of a cold-pressed disc was 0.0046 Ω m, rendering this MXene one of the most conductive to date.
