“…The XRD patterns of ZnO and Ti-ZnO in Figure 5 show the diffraction angles at 2θ of 31.7°, 34.5°, 36.2°, 47.5°, 56.6°, 62.9°, and 68.0° indexed to the crystal planes of (100), (002), (101), (102), (110), (103), and (122), respectively [ 22 , 25 ]. The patterns corresponded well with the hexagonal wurtzite structure of ZnO, according to the standard JCPDS no.…”

“…The other peaks were marked as residuals, including organic compounds and water. The peaks at 1321 and 1644 cm −1 were assigned to C−O stretching and C=O stretching vibrations, respectively [ 22 ]. The peak at 820 cm −1 was attributed to the OH libration, caused by the Zn(OH) 2 phase, and it was consistent with the impurity peak in the XRD results.…”

“…The band gap energy (E g ) was investigated from the diffuse reflectance absorption spectra for ZnO and Ti-ZnO using an ultraviolet-visible-near infrared (UV–Vis-NIR) spectrophotometer (UV-3101 PC, Shimadzu). The recorded spectra were then analyzed according to the Tauc’s relation (Equation (2)) [ 20 , 21 , 22 ]: (αhν) 1/n = A(hν − E g ) where α, A, h, and υ are the optical absorbance coefficient, constant, Planck’s constant, and frequency, respectively. For a direct electron transition material, including ZnO, the parameter n is 1/2.…”

ZnO and Ti-doped ZnO (Ti-ZnO) nanoparticles were synthesized using rapid combustion. The morphology of ZnO and Ti-ZnO featured nanoparticles within cluster-like structures. The ZnO and Ti-ZnO structures exhibited similar hexagonal wurtzite structures and crystal sizes. This behavior occurred because Zn2+ sites of the ZnO lattice were substituted by Ti4+ ions. The chemical structure characterization implied the major vibration of the ZnO structure. The physisorption analysis showed similar mesoporous and non-rigid aggregation structures for ZnO and Ti-ZnO using N2 adsorption–desorption. However, Ti-ZnO demonstrated a specific surface area two times higher than that of ZnO. This was a major factor in improving the photocatalytic degradation of methylene blue (MB). The photocatalytic degradation analysis showed a kinetic degradation rate constant of 2.54 × 10−3 min−1 for Ti-ZnO, which was almost 80% higher than that of ZnO (1.40 × 10−3 min−1). The transformation mechanism of MB molecules into other products, including carbon dioxide, aldehyde, and sulfate ions, was also examined.

“…The relatively wide and distinct peak observed at 3411 cm −1 is indicative of the presence of moisture or the OH band. Finally, the remaining peak at 3016 cm −1 is associated with the stretching of CH bonds 38–40 . During the synthesis of zinc nanoparticles, a noticeable change in color of the solution was observed, transitioning from yellow‐green to white.…”

The utilization of zinc nanoparticles as a bacterial protective layer in the food industry is highly favored. Additionally, the presence of antioxidant and polyphenol compounds in certain herbs can enhance this protective effect. In this study, zinc nanoparticles were synthesized using a green method involving the extract of Anethum graveolens leaves. To assess their antibacterial protection on camel meat against Escherichia coli O157:H7 and Listeria monocytogenes, three protective materials (A. graveolens L., ZnNPs, and Zn [NO3]2) were evaluated at concentrations ranging from 0% to 1% over a period of 20 days. The results demonstrated that ZnNPs (1%) exhibited the best performance, leading to a reduction in the microbial population (Log CFU g−1) of E. coli O157:H7 and L. monocytogenes from 5 to 2.4 and 2.6, respectively. A. graveolens L. extract was the second most effective protective agent. However, it was observed that higher concentrations of all tested substances resulted in improved protection. For instance, the reduction in E. coli O157:H7 count decreased from 5 to 3.25 (Log CFU g−1) with A. graveolens L. (1%), while for L. monocytogenes, it decreased from 5 to 3.5 (Log CFU g−1). Moreover, parameters such as peroxide value (PV), pH, protein carbonyl content, total volatile basic nitrogen (TVB‐N), and thiobarbituric acid reactive substances (TBARS) were effectively controlled, preventing rapid increases. The protective effect of the meat led to lower values of these parameters compared with the control sample. Cytotoxicity assessments confirmed the non‐toxic nature of both A. graveolens L. and ZnNPs. Overall, the findings of this study highlight the potential of combining chemical methods with natural materials to significantly enhance the effectiveness of ZnNPs, ensuring the health and quality of food products.

“…Few studies of Lamiaceae-mediated synthesis of ZnO NPs have been reported on the effect of reaction temperature on the structure, morphology, and properties of ZnO NPs. Algarni et al [93] reported R. officinalis-mediated ZnO synthesised by heating at 80 • C and R. officinalis-mediated ZnO synthesised by autoclaving at 180 • C. According to the TEM results, the ZnO NPs prepared at 80 • C were observed to be predom-inantly spherical with particle sizes ranging from 18 to 40 nm whereas ZnO NPs prepared at 180 • C were mostly elongated with particle sizes from 20 to 123 nm. The particle size of the ZnO NPs increased with an increase in reaction temperature.…”

Antibacterial and Photodegradation of Organic Dyes Using Lamiaceae-Mediated ZnO Nanoparticles: A Review

2022

View full text Add to dashboard Cite

The green synthesis of zinc oxide nanoparticles (ZnO NPs) using plant extracts has been receiving tremendous attention as an alternative to conventional physical and chemical methods. The Lamiaceae plant family is one of the largest herbal families in the world and is famous for its aromatic and polyphenolic biomolecules that can be utilised as reducing and stabilising agents during the synthesis of ZnO NPs. This review will go over the synthesis and how synthesis parameters affect the Lamiaceae-derived ZnO NPs. The Lamiaceae-mediated ZnO NPs have been utilised in a variety of applications, including photocatalysis, antimicrobial, anticancer, antioxidant, solar cells, and so on. Owing to their optical properties, ZnO NPs have emerged as potential catalysts for the photodegradation of organic dyes from wastewater. Furthermore, the low toxicity, biocompatibility, and antibacterial activity of ZnO against various bacteria have led to the application of ZnO NPs as antibacterial agents. Thus, this review will focus on the application of Lamiaceae-mediated ZnO NPs for the photodegradation of organic dyes and antibacterial applications.
