Yongye Liang§, Hailiang Wang§, Hernan Sanchez Casalongue, Zhuo Chen, and Hongjie Dai ()

A graphene/TiO2 nanocrystals hybrid has been prepared by directly growing TiO2 nanocrystals on graphene oxide (GO) sheets by a two-step method, in which TiO2 was first coated on GO sheets by hydrolysis and subsequently crystallized into anatase nanocrystals by hydrothermal treatment. The graphene/TiO2 nanocrystals hybrid shows superior photocatalytic activity to other TiO2 materials in the degradation of rhodamine B, with an impressive three-fold photocatalytic enhancement over P25

Synthesis of Porous NiO Nanocrystals with Controllable Surface Area and Their Application as Supercapacitor Electrodes

Porous NiO nanocrystals with controlled morphology and total surface area have been formed by controlled thermal decomposition and re-crystallization of β-Ni(OH)2. Electrochemical analysis revealed the structure-dependence of the specific charge capacitance for these porous NiO nanocrystals, e.g., 390 F/g for nanocolumns due to their large surface area as high as 102 m2/g, but only 176 F/g for nanoslices with a surface area of 11 m2/g.

The effect of the substrate on the Raman and photoluminescence emission of single-layer MoS2

Michele Buscema (*), Gary A. Steele (*), Herre S. J. van der Zant, and Andres Castellanos-Gomez (*)

We study the Raman and photoluminescence (PL) emission from single-layer molybdenum disulfide (MoS2) on dielectric and conducting substrates. We find that the substrate can strongly affect the Raman and PL emission. We attribute this effect to changes in the substrate-induced doping level and in the decay rates of the excitonic transitions. Our results provide a method to quantitatively study the Raman and PL emission from MoS2-based vertical heterostructures and represent the first step in ad hoc tuning the PL emission of 1L MoS2 by selecting the proper substrate.
