CuO nanoleaf electrode: facile preparation and nonenzymatic sensor applications
We have prepared a CuO nanoleaf electrode by single-step chemical oxidation of a copper foil immersed in alkaline solution. The CuO nanoleaves obtained in this way are perpendicularly orientated towards the copper substrate and are mechanically stable. This results in a high electron transfer rate b...

| description | We have prepared a CuO nanoleaf electrode by single-step chemical oxidation of a copper foil immersed in alkaline solution. The CuO nanoleaves obtained in this way are perpendicularly orientated towards the copper substrate and are mechanically stable. This results in a high electron transfer rate between CuO and the substrate. Scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and cyclic voltammetry were employed to characterize the morphology, growth, structure, and electrochemical properties of the CuO nanoleaf electrode.
