“…Nickel oxide is a wide bandgap semiconductor of the p-type variety, presenting a bandgap that spans from 3.4 eV to 4.0 eV. It has practical applications in the development of antibacterial coatings [4], catalysts, gas sensors, cathodes, dye-sensitized solar cells, antiferromagnetic layers, and electrochromic devices [5][6][7]. Copper oxide is a narrowband semiconductor of the p-type variety with a bandgap that spans from 1.2 to 2 eV [7].…”

This work presents the synthesis of CuO-NiO nanocomposites under different synthesis conditions. Nanocomposites were synthesized by merging a green synthesis process with a microwave-assisted hydrothermal method. The synthesis conditions were as follows: concentration of the metal precursors (0.05, 0.1, and 0.2 M), pH (9, 10, and 11), synthesis temperature (150 °C, 200 °C, and 250 °C), microwave treatment time (15, 30, and 45 min), and extract concentration (20 and 40 mL of 1 g saponin/10 mL water, and 30 mL of 2 g saponin/10 mL water). The phases and crystallite sizes of the calcined nanocomposites were characterized using XRD and band gap via UV-Vis spectroscopy, and their morphologies were investigated using SEM and TEM. The XRD results confirmed the formation of a face-centered cubic phase for nickel oxide, while copper oxide has a monoclinic phase. The calculated crystallite size was in the range of 29–39 nm. The direct band gaps of the samples prepared in this work were in the range of 2.39–3.17 eV.

NiO thin films of different preferred orientations have been growth successfully by sol-gel technique using methanol solvent. The resulting film was analyzed by X-ray diffraction. Phase analysis of the sample was carried out by XRD shown the relative severity of the peak (111) represents a high crystalline of nickel oxide structure. Antibacterial properties of NiO based film against two types of gram-negative bacteria Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) have been evaluated using mac varland method. The antimicrobial activity of the sample was determined through counting the number of colonies on each plate which was reported as colony-forming unit (CFU) per milliliter. Results showed that NiO has high activation efficiency against (E. coli) and (S. aureus).

“…[ 8 ] NiO NPs are utilized for many applications including medicine and drug delivery, [ 9,10 ] colour, catalytic activity, [ 10,11 ] cancer treatment, [ 12 ] optoelectronics and magnetic devices, [ 13,14 ] and ferromagnetic materials. [ 15 ] Some methods have been used for fabrication of NiO NPs, such as sol–gel synthesis, [ 16 ] biosynthesis [ 17 ] and photoirradiation methods. [ 18 ] In general, some of these methods need complicated and expensive equipment set‐ups or need a time‐consuming process as the gelation of the precursor takes a longer period and requires higher annealing temperatures for the as‐prepared samples.…”
