![عکس صفحه اول مقاله: Design of highly electrocatalytically active carbon sphere chains/Au architectures Design of highly electrocatalytically active carbon sphere chains/Au architectures](/preview/png/180305.png)
An advanced carbon paper (CP) macro-substrate (current collector)/submicro-carbon sphere chains, CSCs (catalyst support)/Au (nanocatalyst) architecture was designed and constructed. Gold was deposited onto the surface of CSCs (several microns in length) through pulsed laser deposition to produce a porous ultra-thin film. In sulfuric acid solution, the CSC/Au electrode exhibited a high real surface area of about 36 times higher than that exhibited by a Au wire electrode. The potential utility of the CSC/Au electrode was demonstrated by investigating the electrocatalytic oxidation of glucose, an important clinical biomolecule for both biosensors and implantable biofuel cells. The CSC/Au electrode displayed a prominent response towards the electrocatalytic oxidation of glucose with a peak current of about 676 times superior to that delivered by a Au wire electrode.
► We design and construct current collector-carbon sphere chains-Au thin film layered electrodes.
► High electroactive surface area.
► High catalytic activity for glucose electro-oxidation.
