TiO₂ Nanocrystals Grown on Graphene as Advanced Photocatalytic Hybrid Materials

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

Xiaojun Zhang^1,2, Wenhui Shi¹, Jixin Zhu¹, Weiyun Zhao¹, Jan Ma¹, Subodh Mhaisalkar^1,3, Tuti Lim Maria^4,5, Yanhui Yang⁶, Hua Zhang¹, Huey Hoon Hng¹ (), and Qingyu Yan^1,3 ()

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.

Advanced Asymmetrical Supercapacitors Based on Graphene Hybrid Materials

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

Asymmetrical supercapacitors have been fabricated by coupling a Ni(OH)₂/graphene electrode with a RuO₂/graphene electrode. Growth of Ni(OH)₂ and RuO₂ nanocrystals on high quality graphene sheets affords high-performance hybrid materials for supercapacitors, and the combination of the two materials leads to asymmetrical supercapacitors with high energy and power densities for energy storage applications.

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.
