Multi-redox phenazine/non-oxidized graphene/cellulose nano hybrids as ultrathick cathodes for high-energy organic batteries

Youngjin Ham¹, Vitalii Ri², Jin Kim¹, Yeoheung Yoon³, Jinho Lee¹, Kisuk Kang⁴, Ki-Seok An³ (✉), Chunjoong Kim² (✉), and Seokwoo Jeon¹ (✉)

An ultrathick (≈ 1 mm) organic cathode is developed by utilizing the synergetic effect of the non-covalent functionalized graphene flakes and robust cellulose nanofiber-intermingled architecture. Due to the well-developed ion/electron pathways throughout the entire cathode thickness, the multi-redox phenazine-based organic rechargeable batteries exhibit high energy of 9.4 mWh·cm⁻² (= 864 Wh·kg⁻¹), as well as enhanced cycling stability.

Self-assembly of semiconductor nanoparticles toward emergent behaviors on fluorescence

Xiao Li^1,2, Zhili Lu³, and Tie Wang^1,2,4 (✉)

In this review, we highlight the recent advances in the fluorescence of individual semiconductor nanoparticles, inter-nanoparticles coupling and thus emergent fluorescence behaviors of assemblies. The coupling is the necessary pathway for assemblies beyond individual building blocks to produce emergent fluorescence properties.

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
