“…The intermediate position of this peak suggests that the grapefruit extract produces NiO nanoparticles with a distinct characteristic compared to the other two extracts but shares some similarities with both. The shifts in the absorption peaks among the different fruit extracts highlight the influence of the phytochemical properties of the extracts on the optical properties of NiO nanoparticles, and the results are comparable to the literature [16][17][18]. These variations are a result of the size and morphology differences of the NiO nanoparticles, as well as the type of fruit extracts capping the nanoparticle surfaces.…”

“…This technique takes advantage of plant biodiversity and phytochemicals present in the leaves, fruits and roots, which can influence parameters such as solvent, temperature, pressure, and pH.Several studies have prepared NiO NPs by green syntheses using different plants as capping agents. Various plants/roots/fruit extracts have been reported in the green preparation of NiO NPs are Moringa oleifera [11], Agarose [12], Agathosma betulina [13], Callistemon viminalis [14], Tamarix serotine [15], G. wallichianum leaves extract [16], Peels of fresh Punica granatum [17] and Nephelium lappaceum [18]. However, no report on the use of fresh fruits such as grapes, strawberries and grapefruit.…”

Environmental pollution is a threat to human health, with methyl red dye used in printing and textile dyeing being a notable pollutant that can cause eye, skin, and digestive system irritation. This study investigates the degradation of methyl red dye using nanoparticles of Nickel Oxide (NiO NPs) as photocatalysts. NiO NPs were synthesised at room temperature through thermal decomposition using antioxidant-rich extracts from strawberries (Fragaria ananassa), grapes (Vitis vinifera), and grapefruits (Citrus paradisi). Characterisation of the NiO NPs was performed using FTIR, UV-Vis spectroscopy and SEM. FTIR spectra confirmed the formation of NiO NPs with peaks between 577 – 585 cm–1. UV-Vis spectroscopy showed absorption wavelengths between 322-326 nm for the synthesised NiO NPs and a blue shift to 422-470 nm during methyl red degradation. This study presents a sustainable method for synthesising NiO nanoparticles and demonstrates their effectiveness in environmental remediation, specifically for the removal of pollutant dyes.

“…The band gap energy was found to be 3.47 eV, which was lower than that of the bulk NiO (4.0 eV) due to the quantum confinement effect. Similar studies have reported band gap energies for NiONPs of 4.6 and 3.5 eV using extracts of Stevia rebaudiana and Punica granatum L. (pomegranate) [30,31]. The variation in the band gap energy may be attributed to the difference in the amount of plant extract utilized, the quantity of precursors, the synthesis temperature, as well as the type of extract employed [32].…”

The current study evaluated the biogenic synthesis of nickel oxide nanoparticles (SP-NiONPs) from the root extract of (Salvadora persica) S. persica and their biological properties. The nanoparticles were characterized using spectroscopic and microscopic techniques and then evaluated for their antimicrobial properties against 10 oral pathogens. The ultraviolet-visible (UV–Vis) spectra exhibited a distinctive resonance spectrum at 334 nm for the SP-NiONPs produced from S. persica. The fourier transform infrared (FTIR) analysis revealed the presence of functional groups of biomolecules of S. persica that served as reducing and capping agents of the SP-NiONPs. The scanning electron microscope (SEM) and transmission electron microscopy (TEM) analyses showed that the nanoparticles were spherical-shaped, tightly packed, and ranged in size from 18.20 nm to 45.12 nm. The energy dispersive x-ray (EDX) analysis confirmed 69.9% of the nickel (Ni) content by weight, and the X-ray diffraction (XRD) results showed the face-centered cubic (FCC) crystalline structure of the formed SP-NiONPs. The antioxidant activity of the SP-NiONPs exhibited a dose-dependent profile with an IC50 value of 51.45 ± 0.65 and a 54.13 ± 0.98 DPPH• and ABTS•+ radical scavenging activity, respectively. The SP-NiONPs showed an antibacterial activity against all the test strains; however, E. cloacae was found to be the most sensitive strain, with an inhibition zone of 31 ± 0.50 mm. The SEM image of the E. cloacae cells treated with SP-NiONPs showed irregular shapes and ruptured, destroyed cell membranes. Our findings revealed that SP-NiONPs could be used as excellent antibacterial agents against oral pathogens.

Development of the sustainable materials for consolidation of the energy sustainability needs special emphasis in the current era of the increasing energy demand. In compliance with this, present investigation reports first investigation on the amended sustainable production conjugated with the microwave process of the strontium oxide (SrO) and zinc oxid (ZnO) forming SrO–ZnO nanoscale heterostructure. The band gap of the prepared green nanomaterial was tuned reducing it from 5.8 to 3.6 eV upon the formation of the nanocomposite. With the mixed cubic and hexagonal phase, these particles have average crystallite size of 66.4 nm and irregular shape. The electro‐catalytic assays have expressed the bifunctional role of the SrO–ZnO towards generation of the oxygen and hydrogen. However, it has an excellent hydrogen production capacity with the lower overpotential of 126 mV and Tafel slopes 123.6 mV dec−1. In addition, this nanomaterial has also exhibited superior electrochemical charge storage for batter applications with the unit capacity of 541.7 mAH g−1 and Rs = 0.4 Ω, reflecting facilitated diffusion at the interface. In terms of photovoltaic applications, SrO–ZnO nanocomposite has effectively passivated the perovskite solar cells by improving efficiency from 7.2% to 15.1%. Such an improved performance is associated with the chemical synergism.
