“…Classic reducing agents, such as sodium hydroxide and urea, are usually used for the in situ synthesis of ZnO on PET textiles [11,12]. However, the use of green reducing agents for nanoparticle synthesis is increasing due to health and environmental concerns [13]. In some cases, both classical and plant-derived reducing agents have been used for the in situ synthesis of nanoparticles on textiles [14,15].…”

This article presents green in situ synthesis of ZnO directly on polyethylene terephthalate (PET) fabrics using pomegranate peel extract. The surface of PET was activated by environmentally friendly oxygen plasma, and the process was compared to alkali treatment where the extract of wood ash was used instead of classical chemicals. Sorption analysis showed that the hydrophilic character of the plasma-treated sample was much better than that of the alkali-treated and untreated samples. Both treatments slightly decreased the breaking strength and elongation of the fabric. Scanning electron microscopy, colour measurements, dispersive X-ray spectroscopy, and antioxidant activity investigations showed that the ZnO particles were successfully synthesised on alkali- and plasma-treated PET. The liquid chromatography-mass spectrometry results showed that ellagic acid and punicalagin were the most abundant compounds in the pomegranate peel extract that enabled the synthesis of ZnO. The UV protection, amount of ZnO, and uniformity were the highest for the ZnO prepared on the PET samples by the plasma-assisted green synthesis. Additional optical assessment of fabric porosity and thickness measurements confirmed that these fabrics have excellent UV protection due to the presence of ZnO.

“…These natural biomolecules were mainly composed of polyphenols, which have been found to play an active role in the biosynthesis of nanoparticles from any plant extract capable of forming various shapes and sizes of nanoparticles with enhanced active surface area, characteristics and properties [16]. Therefore, biosynthesis can be considered the safe and environmentally friendly approach for many applications that have used TiO2 nanoparticles [20,21].…”

A New Combination Method of N-doped TiO2 Nanoparticles Synthesis for Heavy Metal Ions Cr(VI) Photoreduction Applications

Through a combination of biosynthetic and hydrothermal methods, N-doped TiO2 photocatalyst has been successfully synthesized using various concentrations of ammonia as a nitrogen source, namely 10% w/w (NTO10), 20% w/w (NTO20), 35% w/w (NTO35), and 50% w/w (NTO50). The synthesis of TiO2 was conducted using Aloe vera (L) Burm F. rind extract as a natural capping agent via the biosynthetic method, followed by a nitrogen doping process via the hydrothermal method. The X-ray Diffraction (XRD) analysis revealed that all phases were anatase. According to the results of the UV-Vis Diffuse Reflectance Spectroscopy (UV-Vis DRS) analysis using the Tauc-Plot method, all N-doped TiO2 samples showed a decrease in the energy gap compared to the TO sample. This indicates that the doping of TiO2 using nitrogen has been successfully doped into TiO2. The photocatalytic activity of N-doped TiO2 was evaluated for the photoreduction of the Cr(VI) model pollutant using a 24-watt LED lamp as a visible light source for 120 minutes. The results indicate that the NTO35 is the best-prepared N-doped TiO2, which showed a reduced rate for the Cr (VI) model pollutant of 50.88%, or two times greater than that of undoped TiO2.

“…The green chemistry‐based synthesis of the NPs is now well recognized as an eco‐friendly paradigm for the fabrication of multifunctional NPs. Green synthesis of the NPs possesses certain advantages like it includes a simple one‐step process, cost‐effectiveness, and easy scaling up to large‐scale production 12 . It has been well‐established that the phytoextracts stabilization of the NPs leads to enhance activity and biocompatibility as compared with the NPs synthesized via chemical and physical routes 13,14 .…”

Phytoextracts modulated synthesis of nano‐scaled spherical lanthanum oxide nanoparticles (La2O3 NPs) are reported using the aqueous extracts of Hyphaene thebaica as a bioreducing and chelating agent. X‐ray diffraction (XRD) pattern revealed sharp peaks and single‐phase purity. The Debye–Scherrer approximation indicated an average crystallite size of 37 nm, whereas W‐H plot revealed a crystallite size of 59 nm, complemented by the high‐resolution transmission electron microscopy (HR‐TEM). The infrared spectroscopy revealed characteristic La‐O band at 426 and 648 cm−1. K‐M function revealed the bandgap of 5.6 eV, whereas broad intense emission peaks between 345 and 750 nm. The Raman spectra revealed peaks at 182, 325, 384, and 491 cm−1. Elemental composition was confirmed using energy‐dispersive X‐ray spectroscopy (EDS) spectrum, and the spotty rings from selected area electron diffraction (SAED) indicated the crystalline nature of the HT‐La2O3 NPs. In addition, the HT‐La2O3 NPs were investigated for in vitro antioxidant, anticancer, antiangiogenic, and cytotoxic potentials. DPPH free radical scavenging activity was highest, that is, 49.54 ± 0.88% at 1000 μg/mL. MTT assay on MCF‐7 and 3T3 cell lines revealed a median lethal concentration of 114 and 43 μg/mL, respectively. The antiangiogenic effect examined by chick chorioallantoic membrane (CAM) assay indicated inhibition of 57.14 ± 0.96% at 1000‐μg/mL concentration with an IC50 of 551 μg/mL. IC50 for the brine shrimp lethality assay was 314.2 μg/mL. Our study indicates cytotoxicity of HT‐La2O3 NPs, and it further concluded that HT‐La2O3 NPs were more potent against 3T3 cells as compared with MCF‐7 cells. Further research on the biological synthesis and anticancer studies are recommended for the large‐scale applications of the La2O3 NPs.
