Synthesis of Graphite Oxide-Wrapped CuO Nanocomposites for Electrocatalytic Oxidation of Glucose

Abstract

GO/CuO nanocomposite had been successfully synthesized by electrostatic interactions method. X-ray powder diffraction(XRD), Scanning electron microscopy(SEM), transmission electron microscope(TEM), selective-area electron diffraction(SAED), Fourier transform infrared spectroscopy(FT-IR), and Raman spectra confirmed the structure of the CuO and GO/CuO nanocomposite. The property of GO/CuO nanocomposite for electrocatalytic oxidation of glucose was investigated by cyclic voltammetry. The experimental results indicate that the GO/CuO nanocomposite modified electrode allows highly sensitive and low working potential of glucose and is promising for the future development of non-enzymatic glucose sensors.

Preparation and characterization of copper oxide nanoparticles decorated carbon nanoparticles using laser ablation in liquid

“…The peaks have well consent with the standard pattern of monoclinic CuO (JCPDS Card No. 05-0661) [18]. In addition, typical diffraction peak of Cu2O (110) and Cu (111) is observable in the XRD pattern for carbon doped by copper oxide nanoparticles at 2θ= 43.2° and 29.56° respectively.…”

Copper Oxide Nanoparticle-Decorated Carbon Nanoparticle Composite Colloidal Preparation through Laser Ablation for Antimicrobial and Antiproliferative Actions against Breast Cancer Cell Line, MCF-7

“…These data are in agreement with the previously reported results [ 41 ]. However, the CNP/CuO NP pattern showed new peaks at 38.5° and 48.64° at 2 θ , corresponding to the (111) and (202) crystal planes, respectively, of CuO, with a monoclinic phase (JCPDS:05-0661) [ 42 ]. This result is consistent with the data previously recorded [ 43 ].…”

In situ growth of copper-based energetic complexes on GO and an MXene to synergistically promote the thermal decomposition of ammonium perchlorate

“…The peak at 532.5 eV in the O 1s spectra is caused by the ionization of O ions (which are formed by the interaction of specific coordination bonds), giving strong evidence that Cu( ii ) coordinates with the O-containing group of GO. 37 Similarly, there are two peaks on the Cu 2p 3/2 curves at 932.9 eV and 935.6 eV (Fig. 8e), which are labeled as Cu–N and C–O–Cu bonds, respectively.…”
