Scanning electron microscopy and X-ray diffraction revealed that the CuO FMs are phase-pure monoclinic crystallites and comprised of CuO nanoflakes. The concentration of NaOH has a large effect on the size of the CuO FMs. The possible formation mechanism is discussed. The CuO FMs are electrocatalytically active towards the oxidation of H2O2, and this has resulted in a sensor for H2O2. To our knowledge, this is the simplest way to obtain clean CuO FMs. Figure A facile electrochemical route, which is carried out at room temperature (25°C), is introduced for the fast fabrication of CuO flower-like microspheres (CuO FMs). The CuO FMs modified glassy carbon electrode exhibits good electrocatalytic activity towards the oxidation of H2O2.
