Benzoxazole and benzimidazole heterocycle-grafted graphene for high-performance supercapacitor electrodes

31-Oct-2012 | Wei Ai; Weiwei Zhou; Zhuzhu Du; Yaping Du; Hua Zhang; Xingtao Jia; Linghai Xie; Mingdong Yi; Ting Yu; Wei Huang, Journal of Materials Chemistry, 2012

An efficient method for the preparation of benzoxazole and benzimidazole covalently grafted graphene and their application as high performance electrode materials for supercapacitors is reported. The synthesis of such covalently functionalized graphene materials first involves a cyclization ...


Influence of pH on the Fluorescence Properties of Graphene Quantum Dots Using Ozonation Pre-oxide Hydrothermal Synthesis

31-Oct-2012 | Feng Yang; Meilian Zhao; Baozhan Zheng; Dan Xiao; Li Wu; Yong Guo, Journal of Materials Chemistry, 2012

Recent research in graphene-based materials is largely focused on graphene quantum dots (GQDs) and their optical properties. A facile method has been developed to extract GQDs from graphene sheets (GSs) by ozonation pre-oxide. The as-prepared GQDs, which are 2 - 4 nm in diameter, exhibit strong ...


Fabrication of two-dimensional hybrid sheets by decorating insulating PANI on reduced graphene oxide for polymer nanocomposites with low dielectric loss and high dielectric constant

31-Oct-2012 | Mi Li; Xingyi Huang; Chao Wu; Haiping Xu; Pingkai Jiang; Toshikatsu Tanaka, Journal of Materials Chemistry, 2012

Novel polyaniline decorated reduced graphene oxide (rPANI@rGO) two-dimensional (2D) hybrids sheets were successfully prepared by in situ polymerization of aniline on graphene oxide (GO) sheets and successive reduction by hydrazine. PANI is heavily reduced, thus it is electrically insulating. The ...


The synergistic effect of graphene and polyoxometalates enhanced electrocatalytic activities of Pt-{PEI-GNs/[PMo12O40]3−}n composite films regarding methanol oxidation

31-Oct-2012 | Zhongshui Li; Xiaomei Huang; Xiaofeng Zhang; Lian Zhang; Shen Lin, Journal of Materials Chemistry, 2012

The {PEI-GNs/PMo12}n composite films are prepared by an LBL electrostatic assembly technique, and their uniform and homogeneous traits have been verified by UV-vis and cyclic voltammetry. The {PEI-GNs/PMo12}n composite films are used as a novel catalyst support for electro-deposition of Pt ...


Large-scale patterning by the roll-based evaporation-induced self-assembly

25-Oct-2012 | Won Kyu Park; TaeYoung Kim; Hyeongkeun Kim; Yena Kim; Tran Thanh Tung; Zhiqun Lin; A-Rang Jang; Hyeon Suk Shin; Jong ..., Journal of Materials Chemistry, 2012

The large-scale fabrication of highly regular polymer stripes was achieved either on rigid or flexible substrates via the roll-based evaporation-induced self-assembly (EISA) method. A control of stripe size was rendered by an adjustment of the jig speed and the polymer concentration. Large-scale ...


Fingerprinting photoluminescence of functional groups in graphene oxide

17-Oct-2012 | Ming Li; Scott K. Cushing; Xuejiao Zhou; Shouwu Guo; Nianqiang Wu, Journal of Materials Chemistry, 2012

Chemically modified graphene oxide (GO) sheets exhibit three “fingerprinting” photoluminescent (PL) peaks, which originate from the σ* → n, π* → π and π* → n electronic transitions between the antibonding and the bonding molecular orbitals. The three PL peaks are associated with the C–OH, the ...


Facile preparation route for graphene oxide reinforced polyamide 6 composites via in situ anionic ring-opening polymerization

17-Oct-2012 | Xiaoqing Zhang; Xinyu Fan; Hongzhou Li; Chun Yan, Journal of Materials Chemistry, 2012

In this study, a new and facile route has been developed to prepare graphene oxide (GO) reinforced polyamide 6 (PA6) composites and synthesize simultaneously PA6 grafted GO hybrid materials: ε-caprolactam (CL) was firstly fixed onto the GO sheets coupling by 4,4′-methylenebis(phenyl isocyanate), ...


An efficient oxygen reduction electrocatalyst from graphene by simultaneously generating pores and nitrogen doped active sites

17-Oct-2012 | Thangavelu Palaniselvam; Harshitha Barike Aiyappa; Sreekumar Kurungot, Journal of Materials Chemistry, 2012

A simple way to simultaneously create pores and nitrogen doped active sites on graphene for the electrochemical oxygen reduction reaction (ORR) is developed. The key aspect of the process is the in-situ generation of Fe2O3 nanoparticles and their concomitant dispersion on graphene by pyrolyzing ...


Hybridization of graphene sheets and carbon-coated Fe3O4 nanoparticles as synergistic adsorbent of organic dyes from water

17-Oct-2012 | Wei Fan; Wei Gao; Chao Zhang; Weng Weei Tjiu; Jisheng Pan; Tianxi Liu, Journal of Materials Chemistry, 2012

Magnetic graphene/Fe3O4@carbon (GFC) hybrids with hierarchical nanostructures have been synthesized and its application as an adsorbent for removal of organic dyes from water has been investigated. Graphene/Fe3O4 hybrids have been first prepared via a facile one-pot solvothermal process, and then ...


Reduced Graphene Oxide-MnO2 Hollow Sphere Hybrid Nanostructures as High-performance Electrochemical Capacitors

17-Oct-2012 | limin Wu, Journal of Materials Chemistry, 2012

This paper presents the first successful fabrication of reduced graphene oxide (RGO)-MnO2 hollow sphere (HS) hybrid electrode materials through a solution-based ultrasonic co-assembly method. The porous structure of these MnO2 hollow spheres and the excellent dispersion of active materials give ...
