“…S9 of the ESI. These images are similar to those reported by Lam et al in their study of the effect on sunlight on films of LDPE doped with photocatalytic particles of ZnO and Fe-ZnO [ 29 ] and reflect the ability of these particles, as with those of TiO 2 , to degrade the encapsulating polymer.…”

“…However, although some self-sterilising work has been conducted on plastic substrates, the photocatalytic films usually comprise a loose coating of photocatalyst powder on the plastic [ 18 , 27 ], which renders them active but neither robust, or flexible. Encouragingly, Lam and his co -workers have used a solvent casting technique to produce films of polyethylene, polystyrene and LDPE impregnated with ZnO-based photocatalysts which exhibit antibacterial activity, although the method of production doesn't appear appropriate for the scalable production of very thin and flexible films [ 28 , 29 ].…”

“…It is noteworthy that plant extracts are composed of numerous biomolecule compounds, such as polyphenols, flavonoids, carbonyl, and protein compounds. These biomolecule compounds could serve as green capping agents and templates and, accordingly, could play pivotal roles in the fabrication process [ 9 ].…”

“…The precipitation method has been used extensively to prepare ZnO NPs [ 9 , 10 , 11 , 12 , 13 , 14 ]. Recently, Lam et al synthesized iron-doped ZnO (Fe-ZnO) nanoparticles according to a simple and green method utilizing Hibiscus rosa-sinensis leaf extract, reporting the properties of these nanoparticles for the inactivation of Escherichia coli ( E. coli ) under sunlight irradiation [ 9 ]. Another example of this method has been reported with Gliricidia sepium leaf extract using direct-sunlight-driven selective photodegradation of methylene blue [ 12 ], showing that it is possible to obtain a high percentage of degradation and selectivity of the material with certain types of dyes.…”

In this work, the assessment of Azadirachta indica, Tagetes erecta, Chrysanthemum morifolium, and Lentinula edodes extracts as catalysts for the green synthesis of zinc oxide nanoparticles (ZnO NPs) was performed. The photocatalytic properties of ZnO NPs were investigated by the photodegradation of methylene blue (MB) dye under sunlight irradiation. UV-visible (UV-Vis) spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy, Transmission Electron Microscopy (TEM), X-ray Diffraction (XRD), Thermogravimetric (TGA), and Brunauer-Emmett-Teller analysis (BET) were used for the characterization of samples. The XRD results indicate that all synthesized nanoparticles have a hexagonal wurtzite crystalline structure, which was confirmed by TEM. Further, TEM analysis proved the formation of spherical and hemispherical nanoparticles of ZnO with a size in the range of 14–32 nm, which were found in aggregate shape; such a size was well below the size of the particles synthesized with no extract (~43 nm). ZnO NPs produced with Tagetes erecta and Lentinula edodes showed the best photocatalytic activity, matching with the maximum adsorbed MB molecules (45.41 and 58.73%, respectively). MB was completely degraded in 45 min using Tagetes erecta and 120 min using Lentinula edodes when subjected to solar irradiation.

The ubiquitous presence of microplastics in the environment has raised serious environmental and health concerns. These tiny plastic particles can enter the food chain, posing a significant threat to human health. Researchers worldwide have focused their efforts on developing strategies to mitigate microplastic pollution. This review focuses on the potential of nano/microstructured metal oxide semiconductors as effective photocatalysts for microplastic degradation. The review is divided into two sections: static metal oxides and dynamic micromachines based on metal oxides. The modifications made to nano/microstructured metal oxides such as TiO2, ZnO, bismuth oxyhalides (BiOX), NiO, Cu2O/CuO, perovskite‐like Bi2WO6, Fe3O4, etc., to enhance their degradation efficiency are thoroughly discussed and reviewed. Additionally, the photocatalytic pathways for the conversion of microplastics into C2 fuel and other value‐added products are also elaborated. The current developments in the realm of dynamic, self‐propelled, and controlled micromotors for the photodegradation of microplastics are also highlighted. The review concludes by proposing future perspectives and challenges to facilitate the remediation of microplastics in water and wastewater systems in a more effective, scalable, and environmentally friendly manner. Overall, the review emphasizes the potential of photocatalysis using nano/microstructured metal oxide semiconductors as an eco‐friendly and promising approach for microplastic degradation.
