Ti3C2 MXene as a High Capacity Electrode Material for Metal (Li, Na, K, Ca) Ion Batteries
TL;DR: Compared to materials currently used in high-rate Li and Na ion battery anodes, MXene shows promise in increasing overall battery performance and is predicted by first-principles density functional calculations.
Journal ArticleDOI
Janus Monolayer Transition-Metal Dichalcogenides
Jing Zhang,Shuai Jia,Iskandar Kholmanov,Liang Dong,Dequan Er,Weibing Chen,Hua Guo,Zehua Jin,Vivek B. Shenoy,Li Shi,Jun Lou +10 more
TL;DR: High basal plane hydrogen evolution reaction activity is discovered for the Janus monolayer, and DFT calculation implies that the activity originates from the synergistic effect of the intrinsic defects and structural strain inherent in theJanus structure.
Journal ArticleDOI
Synthesis of two-dimensional titanium nitride Ti4N3 (MXene)
Patrick Urbankowski,Babak Anasori,Taron Makaryan,Dequan Er,Sankalp Kota,Patrick L. Walsh,Meng-Qiang Zhao,Vivek B. Shenoy,Michel W. Barsoum,Yury Gogotsi +9 more
TL;DR: The first two-dimensional transition metal nitride, Ti4N3-based MXene is synthesised using a molten fluoride salt to etch Al from a Ti4AlN3 powder precursor at 550 °C under an argon atmosphere and delaminated the resulting MXene to produce few-layered nanosheets and monolayers of Ti4n3Tx.

Janus Monolayer Transition Metal Dichalcogenides
Jing Zhang,Shuai Jia,Kholmanov Iskandar,Liang Dong,Dequan Er,Weibing Chen,Hua Guo,Zehua Jin,Vivek B. Shenoy,Li Shi,Jun Lou +10 more
TL;DR: In this article, a novel crystal configuration of sandwiched S-Mo-Se structure (Janus SMoSe) at the monolayer limit has been synthesized and carefully characterized.
Journal ArticleDOI

TL;DR: It is shown that efficient charge injection and the presence of naturally occurring sulfur vacancies are responsible for the observed increase in catalytic activity of the 2H basal planes of monolayer MoS2 nanosheets.
