“…Nanobiotechnology has become an interesting area for the synthesis of nanostructures among researchers due to its low cost, nontoxicity, simplicity, and Eco-friendliness. In the biological synthesis of ZnO nanostructures, scientists used various plant extracts such as Vitextrifolia L.(leaf) [73,74], Zingiber officinale (rhizome) [75], Nepheliumlappaceum L. (fruit peel) [76], Eucalptus globules (leaf) [77] Cappariszeylanica [78], Musa acuminata peel extract [79], ananas comosus [75]. Jamdagni et al [80] used Nyctanthes arbor-tristisdivaricate flower extract to synthesize ZnO NPs in the particle size range of 12-32 nm.…”

Background:The zinc oxide nanostructures have been using in the textile industry since the early 2000s. However, the efficiency of dye removal, antibacterial and UV protection were enhanced by researchers using different techniques. Objective: This review focuses on the latest research of dye removal, UV protection and antibacterial activity with mechanisms, to discover the most efficient methods to apply ZnO nanostructures effectively for the textile industry. Findings: The photocatalytic activity and photosensitivity of ZnO nanostructures were enhanced by doping materials such as Cu, Fe 2 O 3 , Co, Ce, Al, and Mn. The UV protection of ZnO nanostructures was efficient even with low loading percentages and effectively retained in the textiles. However, the dye removal efficiency was increased with pH due to the high concentration of hydroxyl radicals in the media. Although the UV protection ability of ZnO nanostructures in the textile industry was hindered by photocatalytic activity, scientists had overcome this issue by doping impurities such as SiO 2 , cobalt, and manganese. The antibacterial properties of ZnO nanostructures were changed according to the loaded amount of zinc oxide nanostructures on the textile surface. In most of the research, Escherichia coli and Staphylococcus aureus were used as test organisms to study the antibacterial property of ZnO nanostructures. The green synthesis of ZnO nanostructures is more favorable for all applications due to their nontoxicity and eco-friendly nature.

“…Zinc oxide (ZnO) is an inorganic semiconductor in the form of a powder that has a wide band gap compared to other metal oxides [1][2][3]. In addition, ZnO also has unique physical properties [4], capable of absorbing radiation [5], high catalyst activity, and non-toxic properties [5].…”

“…Likewise, rock salt cubic structure is rarely observed [1]. ZnO could be obtained from plant extracts such as aloe vera leaf extract [9], rambutan peel extract [10], polygala tenuifolia root extract [11], rosa canina fruit extract [12], ginger rhizome extract [13], Garcia mangostana fruit extract [14] and pineapple peel extract [15,3,2]. Pineapple fruit is easy to obtain, and the price is low, so the more pineapple production increases, the more waste is generated.…”

The use of pineapple peel has not been paid attention to because of the lack of public knowledge regarding the content and benefits of pineapple skin. However, it can use pineapple skin for herbal drinks and animal feed. Pineapple peel has phytochemical compounds and bioactive compounds such as ZnO. Therefore, this study was conducted to determine ZnO's crystalline phase and the functional group from pineapple peel extract. Synthesis of ZnO from pineapple peel extract used the green synthesis method, with the following steps: pineapple peel was pounded and stirred by heating at 80°C, and then ultrasonicated. The solution was added with NaOH and centrifuged at 4000 rpm. This result is heated at a temperature of 120°C with a 6 and 12 hours holding time. After that, it cooled to room temperature. The results of XRD analysis obtained the optimal ZnO crystalline phase at a holding time of 12 hours according to the pdf cards database (96-210-7060) and nanocrystalline size of 17.55 nm. The FTIR results on the ZnO sample had an absorption peak of 4000-400cm-1 with functional groups O-H alcohol and phenol, -C=C alkene, C=O, C-O, C-N, and Zn-O. It is hoped to be applied later in the medical and industrial fields by obtaining ZnO samples from pineapple peel extract

“…The nanoparticles are synthesized by various ways which involves, the use of hazardous chemicals. It is need of time to develop the environmentally friendly protocols with non-toxic by-products, mild reaction conditions, safety natural material as capping agent as part of the reducing agent (9)(10)(11). It has been observed that the nanomaterial prepared from the plant part as the capping agent are safer, best with good particle morphology and stable (12).…”

In the world industries are growing very rapidly resulting in fast development. Various industries are coming up such as that of dyes, paints, pharmaceuticals etc. Dyes are used in various industries and release pollutants in the environment. It is necessary to remove such pollutants from the environment. Euphorbia neriifolia L. grow as the weed in the forests of the konkan region in waste land area. This weed is a typical latex bearing plant. This latex can be converted into the powder under sun drying process. This powder can be used for the preparation of Fe nanoparticles. The plant assisted synthesized nanoparticles have good particle size, morphology and band gap. These nanoparticles used for the degradation of the dye like Methylene Blue and Methylene Red from the industrial waste. It gives very good results. We can develop new catalyst for the degradation of the dyes from the industrial waste. It act as good catalyst by the simple non form of the catalyst. This catalyst is derived from the plant Euphorbia neriifolia L. latex.
