“…The degradation of MB dyes occurs when the strong oxidizing component (HO • ) attacks them forming carbon dioxide and the water molecule as byproducts (Eq. 14) [33a,61–63] . As shown in the reactions, the O 2 • − and HO • are two leading reactive species for the photodegradation of the MB dyes.…”

Novel bio‐fabricated ZnO nanoparticles were made from the solution of zinc nitrate in the presence of bio‐components of Jasminum grandiflorum L. The bio‐fabricated ZnO nanoparticles, represented as Jg‐ZnO NPs, were suitably characterized by several state‐of‐the‐art tools. The UV‐Vis absorption band at λmax=370 nm and the characteristic XRD peaks at appropriate positions suggest the formation of ZnO NPs. The XRD pattern revealed the formation of highly crystalline, hexagonal phase and impurity free Jg‐ZnO NPs. The presence of biomolecules on the surface of ZnO NPs was confirmed by FTIR spectral analysis. These NPs have hexagonal structures and flake‐like morphology as revealed by their TEM and SEM analysis, respectively. Further, the Jg‐ZnO NPs exhibit excellent photocatalytic activity against the MB dye under sunlight with a dye degradation efficiency of 99.8 %. Besides, the Jg‐ZnO NPs were also remarkably effective in inhibiting the growth of gram‐positive (S. aureus) as well as gram‐negative (P. aeruginosa and K. pneumoniae) pathogenic bacteria.

“…The surface plasmon resonance (SPR) peak serves as a crucial indicator for determining nanoparticle size and uniformity. In this instance, the distinctness of the SPR peak suggests the formation of monodisperse ZnO NPs [65]. Typically, ZnO NPs display a maximum absorption peak wavelength within the 300-380 nm range.…”

The fruit extract of Buchanania Obovata and the eutectic-based ionic liquid were utilized, in an eco-friendly, inexpensive, simple method, for synthesizing zinc oxide nanoparticles (ZnO NPs). The influence of the reducing, capping and stabilizing agents, in both mediums, on the structure, optical, and morphological properties of ZnO NPs was extensively investigated. The surface plasmon resonance peaks were observed at 340 nm and 320 nm for the fruit-based and the eutectic-based ionic liquid mediums, respectively, indicating the formation of ZnO NPs. XRD results confirmed the wurtzite structure of the ZnO NPs, exhibiting hexagonal phases in the diffraction patterns. The SEM and TEM images display that the biosynthesized ZnO NPs exhibit crystalline and hexagonal shape, with an average size of 40 nm for the fruit-based and 25 nm for the eutectic-based ionic liquid. The BET surface area analysis, revealed a value ~13 m2 g−1 for ZnO NPs synthesized using the fruit extract and ~29 m2 g−1 for those synthesized using the eutectic-based ionic liquid. The antibacterial activity of the biosynthesized ZnO NPs was assessed against clinically isolated Gram-negative (E. coli) and Gram-positive (S. aureus) bacterial strains using the inhibition zone method. The ZnO NPs produced from the eutectic-based ionic liquids confirmed superior antibacterial activity against both S. aureus and E. coli compared to those mediated by the utilized fruit extract. At a concentration of 1000, the eutectic-based ionic liquid mediated ZnO NPs displayed a maximum inhibition zone of 16 mm against S. aureus, while against E. coli, a maximum inhibition zone of 15 mm was observed using the fruit extract mediated ZnO NPs. The results of this study showed that the biosynthesized ZnO NPs can be utilized as an efficient substitute to the frequently used chemical drugs and covering drug resistance matters resulted from continual usage of chemical drugs by users.

Zinc oxide (ZnO) has several industrial applications due to its versatile properties, which lead to its continuously increasing demand in different industrial sectors. Additionally, ZnO nanostructures possess unique photocatalytic activity, and because of this, they are being applied to degrade organic dyes through photocatalysis for wastewater treatment. Nevertheless, chemical synthesis methods to develop ZnO nanostructures have raised concerns related to environmental issues, furthermore, these methods are found to be costly and tedious. As a result, the synthesis of ZnO nanostructures using green methods is gaining popularity due to its low cost and eco‐friendly mode, while avoiding the use of toxic chemicals. Green synthesis of ZnO nanostructures using different biological approaches involving plants, algae, and different microorganism‐derived bioactive compounds has been well reported for diverse applications. Among different applications, ZnO nanostructures that enable photocatalysis to degrade dye have been found to be imperative for wastewater treatments. Therefore, the current review explores recent studies on green synthesis approaches to prepare ZnO nanostructures via adopting different biological methods that rely on plants, algae, and bacterial microorganisms. The properties of ZnO nanostructures, along with their green synthesis routes and feasible mechanisms, have also been discussed in this review. This review focuses on the use and efficiency of green route synthesized ZnO nanostructures as nanophotocatalysts for the degradation of organic dyes in wastewater treatment. Additionally, existing challenges in green synthesis methods and the efficiency of ZnO nanostructures to degrade organic dyes following photocatalysis has been discussed.
