“…2, a single strong diffraction peak at 20°(2θ scale) can be found obviously, indicating the existence of the Cu phase, which can be further confirmed by another weaker peak at 25°. Besides, four other weak diffractions at approximately 35, 39, 51 and 60°can also be detected, which just corresponded to the diffraction peaks from the −111, 111, −202, to −113 planes of CuO [30,31]. Therefore, the XRD of the deposited nanoparticles indicated that Cu and CuO nanoparticles were present on the surface of the modified electrode.…”

A new electrochemical sensor for H 2 O 2 was constructed by depositing copper doped CuO nanosheets on a glassy carbon electrode (GCE). The morphology and composition of the modified electrode were characterized via scanning electron microscopy, energy dispersive X-ray spectroscopy and X-ray diffraction. The electrochemical properties of the electrode were studied using cyclic voltammetry and electrochemical impedance spectroscopy. The catalytic performance of the sensor was studied in 100 mM NaOH solution via differential pulse voltammetry and revealed the sensor to display significantly improved electrocatalytic activity with respect to the analysis of the H 2 O 2 in comparison to a plain GCE or a GCE modified with copper only. The response to H 2 O 2 at a working voltage of −0.46 V (vs. Ag/AgCl) is linear in the 0.003 -8 mM concentration range, and the detection limit is 0.21 mM (at an S/N ratio of 3). Satisfactory results were obtained in the analysis of tap, rain and river waters spiked with H 2 O 2 . The analytical performance of this electrode compares favorably to the results obtained with other commonly used techniques for analysis of H 2 O 2 .

“…9. Emission peaks at 352 nm and 462 nm were observed in the sample, which indicated CuO emission [27,28]. The main emission peak observed around 352 nm is attributed due to the near-band-edge (NBE) UV emission.…”
