Journal ArticleDOI
Pyridinic N doped graphene: synthesis, electronic structure, and electrocatalytic property
Zhiqiang Luo,San Hua Lim,Zhiqun Tian,Jingzhi Shang,Linfei Lai,Brian MacDonald,Chao Fu,Zexiang Shen,Ting Yu,Ting Yu,Jianyi Lin +10 more
TL;DR: In this article, a single layer graphene was synthesized with pure pyridinic N by thermal chemical vapour deposition of hydrogen and ethylene on Cu foils in the presence of ammonia.
Journal ArticleDOI
One-step synthesis of NH2-graphene from in situ graphene-oxide reduction and its improved electrochemical properties
Linfei Lai,Linfei Lai,Luwei Chen,Da Zhan,Li Sun,Jinping Liu,San Hua Lim,Chee Kok Poh,Zexiang Shen,Jianyi Lin +9 more
TL;DR: In this paper, primary amine modified graphene (NH2-G) is used to obtain a high specific capacitance with a current density of 0.4 A/g, superior over commercially available GO, chemically reduced GO, activated carbon, and CNT.
Journal ArticleDOI
Thickness-dependent reversible hydrogenation of graphene layers.
Zhiqiang Luo,Ting Yu,Ki-Jeong Kim,Zhenhua Ni,Yumeng You,San Hua Lim,Zexiang Shen,Shanzhong Wang,Jianyi Lin +8 more
TL;DR: Hydrogen coverage investigation and micro-X-ray photoelectron spectroscopy characterization demonstrates that the hydrogenation of single layer graphene on SiO(2)/Si substrate is much less feasible than that of bilayer and multilayer graphene.
Journal ArticleDOI
A glucose biosensor based on electrodeposition of palladium nanoparticles and glucose oxidase onto Nafion-solubilized carbon nanotube electrode.
TL;DR: The co-deposited Pd-GOx-Nafion CNT bioelectrode retains its biocatalytic activity and offers an efficient oxidation and reduction of the enzymatically liberated H2O2, allowing for fast and sensitive glucose quantification.
Journal ArticleDOI
Pt Nanoparticles Supported on Nitrogen-Doped Porous Carbon Nanospheres as an Electrocatalyst for Fuel Cells
TL;DR: In this article, Nitrogen-doped porous porous carbon nanospheres (PCNs) with a high surface area were prepared by chemical activation of nonporous carbon nanoscheres (CNs).
