“…A definite peak broadening indicates that the synthesized material contains the particles in the nanoscale range was obtained at λ ¼ 1.54 A 0 by using X-Ray Diffractometer No: 36-1451 (Figure 5). There was the similarity of the lattice planes reported in previous literature of ZnO nanoparticles synthesis from Ixora Coccinea leaf extract [72], Cinnamomum Tamala [76], Laurus nobilis [77], and Costus pictus leaf extracts [56]. Therefore, it was confirmed that the synthesized ZnO nanoparticles exhibit a hexagonal wurtzite structure with slight agglomeration.…”

The plant extracts are known for their anti-inflammatory, antifungal, antiviral and antibacterial properties. The use of plant extracts in the preparation of bio-materials increases their biological application. In this concern, herein reporting an eco-friendly procedure which is also a simple and cost effective, for the synthesis of Zinc Oxide nanoparticles (ZnONPs) using Saussurea lappa plant root (rhizome) extract as a fuel. The prepared nanoparticles were confirmed using various characterization techniques. The Dynamic light scattering data showed 123.5 nm particle size with -99.9 mv zeta potential which indicates excellent stability of the particles. The peak at 541 cm À1 in the IR spectrum is assigned to the stretching frequency of the zinc-binding to oxygen. The X-ray diffraction peaks confirm the close association with JCPDS Data Card No: 36-1451. The FESEM data revealed a hexagonal wurtzite structure with a hexagonal shape of synthesized ZnO nanoparticles. The antibacterial studies indicate the gram-negative strains showed better inhibition activity than gram-positive strains. Among Fungal strains, Aspergillus niger and flavus, Fusarium oxysporum, and Rhizopus oryzae showed good inhibition activity at higher concentrations. The cytotoxic data indicates the 5 μg/mL of the ZnO particles showed cytotoxicity on the CHO cell line and with IC 50 value 3.164 AE 0.8956 μg/mL.

“…Similarly, the FTIR peak analysis of CT-Fe 3 O 4 NPs revealed that a broadband 3280 cm −1 was due to O-H stretching from the eugenol-OH present in the aqueous extract of CT leaf. The other significant bands at 1620 cm −1 (for carbonyl stretching) match well with the reported CT extract IR at 1638 cm −1 [54]; 2922 cm −1 (for C-H stretching) and 1059 cm −1 (for C-O stretching vibration) confirmed the formation of CT leaves extract-coated MNPs [55] (Figure 3b). Similarly, the FTIR peak analysis of CT-Fe3O4 NPs revealed that a broadband 3280 cm −1 was due to O-H stretching from the eugenol-OH present in the aqueous extract of CT leaf.…”

Adsorption of organic pollutants, toxic metal ions, and removal of harmful bacteria can give us clean and pure drinkable water from wastewater resources. Respective magnetite nanoparticles (MNPs) were synthesized using a cheaper and greener way in an open-air environment with the use of crude latex of Jatropha curcas (JC) and leaf extract of Cinnamomum tamala (CT). Characterization of MNPs had been performed by dynamic light scattering (DLS), Ultraviolet-visible (UV-vis) spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, powdered X-ray diffraction (XRD), and field emission scanning electron microscope (FE-SEM). The size ranges of the synthesized MNPs were observed in between 20–42 nm for JC-Fe3O4 and within 26–35 nm for CT-Fe3O4 by FE-SEM images. The effect of synthesized magnetic nanoparticles in wastewater treatment (bacterial portion), dye adsorption, toxic metal removal as well as antibacterial, antioxidant, and cytotoxic activities were studied. This purification will lead to an increase in the resources of pure drinking water in the future.

“…Figure 5 presents results of XRD analysis for ZnO NPs synthesised in microwave reactor at 450 W. Phase analysis revealed that pure zinc oxide with a zincite structure was present. The diffractogram confirmed the presence of a peak at the following 2 : 31.77 (100), 34.41 (002), 36.26 (101), 47.54 (012), 56.59 (110) [42]. The narrow diffraction peaks of the ZnO pattern indicated a good crystallinity of the material [43].…”

The continuous microwave synthesis of ZnO, ZnO–nAg and ZnO–nCu nanoparticles (NPs) are presented. Initially, pure ZnO nanoparticles were synthesised, studying the effect of selected parameters on the size of crystallites. In the second stage, ZnO nanoparticles modified with metal nanoparticles were obtained by conducting the process in a flow system. Tannic acid was used as a reducing agent of silver and copper ions. The structure, crystallinity and effectiveness of the deposition of metal nanoparticles were assessed by XRD, XPS, FTIR and electron microscopy techniques (SEM and TEM). The obtained materials were tested for their photocatalytic properties against methylene blue in UV light. The results of photodegradation in ultraviolet light have shown that the introduction of metal nanoparticles, especially silver nanoparticles, significantly increases catalytic efficiency (30% for pure ZnO NPs, 91% for ZnO–nAg NPs and 54% for ZnO–nCu NPs). The main advantage of the proposed ZnO/Ag semiconductor is that it delays the recombination process of electron–hole pairs generated by photon absorption, which extends the efficiency of such a photocatalyst. Based on the research, we determined that it is possible to use photocatalytically active ZnO modified with metal nanoparticles obtained in the flow process. Graphic abstract
