B,N,S tri-doped Reduced Graphite Oxide-Cobalt Oxide Composite: A Bifunctional Electrocatalyst for Enhanced Oxygen Reduction and Oxygen Evolution Reaction

26-Jun-2018 | Sagar Ingavale; Indrajit Patil; Haridas Babaso Parse; Niranjan S Ramgir; Bhalchandra Anand Kakade; Anita Swami, New Journal of Chemistry, 2018

In the present study, we followed a unique approach to synthesize a nanocomposite of B,N,S tri-doped graphite oxide and cobalt oxide. Initially, B,N,S tri-doped carbon quantum dots were prepared by hydrothermal method using boric acid and L-cysteine as precursors, which were further immobilized ...

Reactions of SO2 and NH3 with epoxy groups on the surface of graphite oxide powder

31-May-2018 | Wenjing Xie; Lu-Tao Weng; Chak-Keung Chan; King Lun Yeung; Chi-Ming Chan, Physical Chemistry Chemical Physics, 2018

Graphite oxide powder was obtained using the modified Hummers’ method and characterized using X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS). The XPS results indicated that the epoxy groups were the main functional groups on the graphite oxide ...

Large-scale synthesis of fluorinated graphene by rapid thermal exfoliation of highly fluorinated graphite

30-May-2018 | Michael Herraiz; Marc Dubois; Nicolas Batisse; Samar Hajjar-Garreau; Laurent Simon, Dalton Transactions, 2018

Weakly fluorinated graphene nanosheets were efficiently prepared via fast thermal exfoliation of highly fluorinated graphite. This scalable method consists of a fast temperature increase (around 10 °C s−1) of fluorinated HOPG performed under an argon atmosphere, without any post-treatment. The ...

Electrochemically controlled winding and unwinding of substrate-supported carbon nanoscrolls

30-May-2018 | H. Tarábková; Z. Zelinger; P. Janda, Physical Chemistry Chemical Physics, 2018

Carbon nanoscrolls (CNSs) formed spontaneously on the basal plane of highly ordered pyrolytic graphite (HOPG) show winding and unwinding movements when potential steps from 0 V to −0.5 V, −0.6 V and −0.9 V are applied on HOPG immersed in an aqueous electrolyte solution (0.1 M H2SO4). Reversible ...
