In the present work, a green synthesis of copper oxide nanoparticles (CuO NPs) has been performed through a precipitation method using three different copper precursors and sylvestrys leaf extract as a capping agent. Morphology and structure of the obtained CuO NPs were confirmed by X‐ray diffraction (XRD), ultraviolet‐visible (UV/Vis), Fourier transform infrared (FT‐IR) and Raman spectroscopy, as well as scanning electron microscopy (SEM). Moreover, their thermal behavior and catalytic performance were studied using thermogravimetry (TG) and differential scanning calorimetry (DSC). Four isoconversional kinetic methods have been applied to the DSC data obtained at different heating rates in order to determine the kinetic triplets. The results showed that the introduction of CuO NPs has noticeably lowered the thermal decomposition temperature by 91.7, 89.9, and 83.0 °C, and increased the exothermic enthalpy by 1053, 832, and 962 J·g–1 for AP‐CuO‐S, AP‐CuO‐N, and AP‐CuO‐Cl, respectively. Furthermore, CuO NPs were found to reduce the activation energy of AP decomposition. Besides that, ammonium perchlorate decomposes following different reaction models g(α), depending on the decomposition stage and the addition of CuO NPs. These results indicate further that the green synthesized CuO nanoparticles are promising ballistic modifiers for composite solid propellants.

“…The peaks for Cu 2p3/2 and Cu 2p 1/2 occurred at 933 and 953 eV, respectively, with a separation of 20 eV [ 36 ]. Shake−up satellite peaks for both Cu 2p 3/2 and 2p 1/2 were observed at approximately 9 eV higher binding energy [ 37 ]. The shape and peak positions of the copper spectra and their shake−ups are consistent with the spectra of CuO [ 38 , 39 , 40 ].…”

This study explores a simple method of fabricating hybrid supercapacitor electrodes, which could potentially broaden the application of this technology. The method involves electrospinning a uniform solution of Matrimid/Metal−Organic Polyhedra 18 (MOP−18) followed by carbonization at a relatively low temperature of 700 °C in air, rather than in an inert atmosphere, to create free−standing, redox−active hybrid supercapacitor electrodes. Additionally, the synthesis procedure requires no stabilization or activation steps, which enhances the cost effectiveness of the synthesized electrode materials. The resulting C/CuO composite was used as the working electrode, with a polyacrylonitrile (PAN)/Poly(methyl methacrylate) (PMMA) carbon nanofiber (CNF) electrode as the counter and 6 M KOH as the electrolyte in a T−cell configuration. The cell performance and redox activity were evaluated using cyclic voltammetry (CV), galvanostatic charge–discharge (GCD), electrochemical impedance spectroscopy (EIS) and cycling stability tests. Additionally, the physical and chemical structures of the electrode materials were assessed using X−ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron spectroscopy (TEM), X−ray diffractometry (PXRD), surface area analysis and other characterization techniques. The electrode material demonstrated a specific capacitance of up to 206 F/g. Supercapacitors utilizing this material display an energy density of 10.3 Wh/kg (active material) at a current density of 1 A/g in electrochemical testing.

“…It can be utilized in a broad range of fields, such as photodetectors, batteries, supercapacitors, magnetic recording devices, and catalysis, among many others. Scientists are now motivated to manipulate its size and shape for optimal performance because of these characteristics (Ibupoto et al, 2018;Xu et al, 2020;Zhao et al, 2021). Effective biotic chemicals called copper compounds are frequently utilized in pesticide formulations and medical applications (Naika et al, 2015).…”

In recent times, environmental pollution has become a pressing issue. Different methods have been developed to detach hazardous materials from H2O bodies. Among these techniques, photo-catalysis has emerged as a low-cost and advanced method. However, finding a potent photocatalyst has been a topic of considerable research. Our study prepared CuO from copper acetate using hydrothermal treatment in an autoclave at 170 ºC for 14 hours. We introduced various quantities of Fe by adding FeSO4 mixture to Cu (CH3COO)2, following the identical method for preparing CuO. The resulting precipitate was cleaned with deionized H2O and dried at 100 °C. The prepared substance was then heated at 450 ºC in a muffle furnace for 60 minutes. We characterized the manufacture of photocatalysts utilizing various techniques such as Ultraviolet (UV), FT-IR, SEM, EDX, and XRD. Our Ultraviolet (UV) spectrum analysis helped us recognize the adsorption spectroscopic analysis of un-doped and doped CuO with various ratios of Fe. FTIR spectroscopic analysis helped us identify functional groups in CuO NPs. Our XRD study showed the monoclinic composition of copper oxide nanoparticles. The SEM picture suggested that NPs exist in a spherical shape. We studied the catalytic activity of synthesized NPs concerning crystal violet (CV) colorant degradation below a direct ray of light irradiation. Our results showed that the degradation productiveness, as compared to CV colorant, was about 93.52% in 180 min. This research is of great importance in the quest for effective and sustainable solutions to environmental problems. The examination of electrical properties highlighted the promising aspects of Fe-doped CuO, particularly at 6% doping. This variant demonstrated superior dielectric parameters, lower tangent loss, semiconductor-like impedance behavior, and enhanced electrical conductivity, emphasizing its potential for applications in electrical and energy storage domains.
