The preparation, characterization, and application of Nickel oxide (NiO)–Copper oxide (CuO)–Zinc oxide (ZnO) transition nanometal oxides have significantly enhanced their tunable properties for superior multifunctional performances compared with well-known metal oxides. NiO–CuO–ZnO nano transition metal oxides were synthesized by a simple eco-friendly solution combustion method. X-ray diffraction studies revealed distinct phases such as monoclinic, cubic, and hexagonal wurtzite for CuO, NiO, and ZnO, respectively, with NiO having the highest composition. The particle sizes were found to be in the range between 25 and 60 nm, as determined by powder X-ray diffraction. The energy bandgap values were found to be 1.63, 3.4, and 4.2 eV for CuO, ZnO, and NiO, respectively. All metal oxides exhibited a moderate degradation efficiency for AR88 dye. The results of ultraviolet–visible absorption spectra helped identify the bandgap of metal oxides and a suitable wavelength for photocatalytic irradiation. Finally, we concluded that the electrochemical studies revealed that the synthesized materials are well suitable for sensor applications.

The search for novel materials has recently brought research attention to alkali metal-based chalcogenides (ABZ) as a new class of semiconducting inorganic materials. Various theoretical and computational studies have highlighted many compositions of this class as ideal functional materials for application in energy conversion and storage devices. This Perspective discusses the expansive compositional landscape of ABZ compositions that inherently gives a wide spectrum of properties with great potential for application. In the present paper, we examine the technique of synthesizing this particular class of materials and explore their potential for compositional engineering in order to manipulate key functional properties. This study presents the notable findings that have been documented thus far in addition to outlining the potential avenues for implementation and the associated challenges they present. By fulfilling the sustainability requirements of being relativity earth-abundant, environmentally benign, and biocompatible, we anticipate a promising future for alkali metal chalcogenides. Through this Perspective, we aim to inspire continued research on this emerging class of materials, thereby enabling forthcoming breakthroughs in the realms of photovoltaics, thermoelectrics, and energy storage.

The solution combustion approach was used to synthesize the CuO-doped ZnO (CuO@ZnO) nanoparticles (NPs) from pure CuO at various concentrations of 5, 10, and 15%. Electron microscopy and X-ray diffraction (XRD) techniques were used to identify the production and structural studies of CuO@ZnO NPs (SEM). For the (111) strong peak, the average crystallite size was determined and was shown to decrease as the concentration of CuO increased. Kubelka-Munk theory was used to determine the optical band gap (Eg) of CuO@ ZnO NPs. The Eg values were found to be 2.6, 2.3, 2.20, and 2.16 eV for pure CuO, 5, 10, and 15 wt.% CuO@ZnO NPs, respectively. This corroborates that the optical band gap reduces with increasing the CuO atoms in the ZnO lattice. Under visible light illumination, the direct green (DG) and fast blue (FB) decolorization methods were used to estimate the photocatalytic performance of CuO with 10%ZnO NPs. These NPs' photocatalytic capabilities can be utilized in environmental applications to purify water. Electrochemical analysis using cyclic voltammetry revealed an improved redox potential output in the electrode crafted with graphite powder in 0.1 N HCl electrolyte solution. These CuO@ZnO electrodes were used because of their capacity to detect an extremely dangerous chemical like arsenic.
