Journal ArticleDOI
Highly effective visible-light-induced H(2) generation by single-layer 1T-MoS(2) and a nanocomposite of few-layer 2H-MoS(2) with heavily nitrogenated graphene.
TL;DR: Two sorts of MoS2 : A single-layer, metallic form of MoM2 (1T-MoS2) and a nanocomposite of a second form ofmoS2 (few-layer 2H-Mo S2) with heavily nitrogenated reduced graphene oxide (NRGO; N content ca. 15 %) show outstanding performance in the production of H2 under visible-light illumination.
Journal ArticleDOI
Graphene analogues of inorganic layered materials.
TL;DR: This Review provides an up-to-date account of these emerging two-dimensional nanomaterials and important aspects such as spectroscopic and optical properties, magnetic and electrical properties, as well as applications.
Journal ArticleDOI
Oxygen redox chemistry without excess alkali-metal ions in Na2/3[Mg0.28Mn0.72]O2

TL;DR: Na2/3[Mg0.28Mn0.72]O2 exhibits an excess capacity and it is shown that this is caused by oxygen redox, even though Mg2+ resides in the TM layers rather than alkali-metal (AM) ions, which demonstrates that excess AM ions are not required to activate oxygenRedox.
Journal ArticleDOI
Superstructure control of first-cycle voltage hysteresis in oxygen-redox cathodes
Robert A. House,Urmimala Maitra,Miguel A. Pérez-Osorio,Juan G. Lozano,Juan G. Lozano,Liyu Jin,James W. Somerville,Laurent Duda,Abhishek Nag,A. C. Walters,Ke-Jin Zhou,Matthew R. Roberts,Peter G. Bruce +12 more
TL;DR: In oxygen-redox intercalation cathodes, voltage hysteresis can be avoided by forming cathode materials with a ‘ribbon’ superstructure in the transition metal layers that suppresses transition metal migration.
Journal ArticleDOI
Comparative Study of Potential Applications of Graphene, MoS2, and Other Two-Dimensional Materials in Energy Devices, Sensors, and Related Areas
TL;DR: The hydrogen evolution reaction facilitated by graphene, MoS2, and related materials is examined and should be useful in making a judicious choice of which 2D material to use for a particular application.
