“…According to the literature, Fe/CuO nanoparticles were created. [35] In a typical experiment, 0.15 mol urea, Cu(NO 3 ) 2 .3H 2 O, and FeSO 4 .7H 2 O were mixed in 0.015 mol (the Fe to Cu mole ratio was 5 %) and dissolved in 150 mL of deionized water while stirring. The mixed solution was transferred to a stainless-steel Teflon-lined autoclave with a capacity of 200 mL.…”

Among various enzyme-free sensors, transition metals and their oxides have been used as suitable modifiers for the design of glucose electrochemical sensors due to their availability and low cost. In the present study, a flexible, enzyme-less, nonwoven fabric-based glucose sensor was developed. We synthesized the Fe-doped CuO (Fe/CuO) chemically and used it as a modifier to the carbon paste to achieve this. A working electrode was created by stabilizing the paste on a nonwoven fabric. The fabric used did not require any pre-preparation except cleaning. The synthesized Fe/CuO was characterized using scanning electron microscopy (SEM), energy-dispersive Xray spectroscopy (EDX), electrochemical impedance spectro-scopy (EIS), diffuse reflectance spectroscopy (DRS), and X-ray diffraction (XRD). The electrochemical properties of the Fe/CuO nanocomposite on the textile electrode were investigated using cyclic voltammetry, amperometry, and electrochemical impedance spectroscopy. In the proposed enzyme-free sensor, Fe/CuO catalyzed the oxidation of glucose on the electrode surface. The sensor has high sensitivity, a wide linear range (2.5 × 10 À 3 -6.57 mM), a low detection limit (8.0 × 10 À 4 mM), long-term stability, and good selectivity. Finally, the sensor was used to determine the amount of glucose in a human sweat sample.

In the last decade the metal oxide NPs are the promising applications in the research field. The lot of methods to available in the synthesis of NPs, but co-precipitation method is very simple, low cost and environmental friendly. The different percentage (Fe 2+ ) doped copper oxide (CuO) NPs prepared by co-precipitation method. XRD pattern confirms the samples are crystalline in monoclinic structure identified by the JCPDS Card. No (80-0076). The doping concentration increases the crystalline size also decreases. CuO NPs based functional groups are identified from FTIR spectra. UV-Vis Spectroscopy the Fe doped CuO has a band gap is determined in the range of 3.57 to 3.62 eV. The Pl emission spectra revealed a blue shift after introducing Fe into CuO structure, from these studies is better for the preparation of CuO nanoparticles. SEMthe surface morphology of the as prepared CuO nanoparticles has identified by SEM studies the indefinite and closely packed grain is observed. The EDAX spectra showed presence copper, Fe and oxygen atoms.

Porous manganese (Mn)-doped copper (II) oxide (CuO) microplates were synthesized by a facile hydrothermal method. The as-prepared samples were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Brunauer-Emmett-Teller N 2 adsorption-desorption analysis and Fourier transform infrared spectroscopy. It is shown that the morphologies of samples can be transformed from hierarchical porous microspheres to microplates by doping with manganese ions. The manganese-doped copper (II) oxide (10%) has a wide pore size distribution from micropore to macropore, and its surface area is 16·82 m 2 /g, which is 2·4 times that of copper (II) oxide microspheres (6·92 m 2 /g). It shows excellent adsorption properties for potassium ethyl xanthate. The saturated adsorption capacity of porous manganese-doped copper (II) oxide (10%) microplates for potassium ethyl xanthate is 5219 mg/g, which is 6·4 times that of copper (II) oxide microspheres (813 mg/g). The excellent adsorption property is mainly attributed to the intrinsic structure and the large specific surface area. This approach is expected to be extended to the preparation of other porous materials.Langmuir constrants m mass of the sample (g) q e adsorption capacity (mg/g) V volume of solution
