FeSnO2 nanocomposites were synthesized via the green method using aqueous leaf extracts of Lawsonia inermis and Phyllanthus embilica plants. The role of polyphenols based on reduction potentials for the synthesis of FeSnO2 was also highlighted. The synthesized materials were examined by using TGA and DSC, FT-IR, XRD, and SEM with EDX analysis. Tetragonal rutile and distorted hexagonal structures were observed in SEM images of the FeSnO2 nanocomposites and compared with an FeSnO2 nanocomposite prepared using the sol-gel method. Scherer’s formula yielded crystallite sizes of 29.49, 14.54, and 20.43 nm; however, the average crystallite size assessed employing the Williamson–Hall equation was found to be 20.85, 11.30, and 14.86 nm by using the sol-gel and green techniques, using extracts from Lawsonia inermis and Phyllanthus embilica. The band gap was determined by using the Tauc and Wood equations, and photocatalytic activity was analyzed to determine the degradation of methylene blue (MB) and crystal violet (CV) under the illumination of natural sunlight. It was observed that the sample prepared by means of the green method using the leaf extract of Lawsonia inermis showed the best photocatalytic activity of 84%, with a particle size of 14.54 nm, a 3.10 eV band gap, and a specific surface area of 55.68 m2g−1.

“…N:SnO 2 nano-powder crystals were produced by Liu et al via a solid-phase reaction technique that involved the utilizing of a surfactant, i.e., sodium p-toluene sulfonate (STS), and the process was performed at room temperature. The results showed enhanced degradation capacity of rice straw powder treatment wastewater (RSPTW), which occurs due to the formation of free radicals because of a low calcination temperature [18]. These studies demonstrate the potential of N:SnO 2 NPs as photocatalysts for dye degradation, and suggest that further research on N:SnO 2 NPs could lead to the development of more efficient and effective methods for the elimination of aqueous dyes.…”

Environmental adulteration is an emerging concern due to the discharge of wastewater effluents from several sources. Several carcinogenic dyes are the major contaminants in these water bodies. These could cause long-lasting and detrimental effects to humans as well as aquatic ecosystems. For efficient degradation of such dyes, the exploration of nanotechnology has demonstrated huge potential. Herein, the degradation of dyes (MB, CV, and MO) has been carried out photocatalytically using N-doped SnO2 nanoparticles (N:SnO2 NPs) as well as in presence of a sacrificial agent, EDTA. These NPs were synthesized at an ambient temperature. Different characterization techniques were used throughout the analysis of the synthesized NPs. The PXRD analysis reveals formation of single-phase rutile structure with tetragonal symmetry. Using the Scherrer formula, the size of the NPs was found to be less than 5 nm, exhibiting increases in size with N doping. Further, morphological analysis through field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) examined the existence of highly agglomerated, spherical NPs. The thermogravimetric analysis (TGA) results depict the thermal stability of the synthesized NPs up to a temperature of 800 °C. These synthesized N:SnO2 NPs exhibit potent efficiency for the photocatalytic degradation of MB, MO, and CV dyes with an efficiency of 93%, 83%, and 73% degradation, respectively, under UV light irradiation. Additionally, the effect of the sacrificial agent, EDTA, was observed on the degradation process and resulted in a degradation of ~90% MB dye, 88% CV dye, and 86% MO dye within 15 min of UV light irradiation.

“…This implies that there are still unreactive primary or secondary alcohol hydroxyl group in glycerol remaining in the solid-phase reaction process of deprotonation of glycerol with metal salts. The two weaker absorption peaks at 2730 and 2827 cm À1 are assigned to the asymmetric and symmetric stretching vibration peaks of the C H bond, 31 respectively. The peak at 2360 cm À1 is stretching vibration of C O bond, it is due to CO 2 can be activated by the Zn O bonds from the surface of glycerin zinc at room temperature, [32][33][34][35] and CO 2 forms two different stable adsorption sites in a linear form, 36 producing the trace amount carbonate species.…”

To explore the simple preparation method of glycerol metal chelates and effectively expand the application field of glycerol metal chelates and biomass glycerol, the micro-nanopowders such as glycerin zinc (Gly-Zn), and glycerin bismuth (Gly-Bi) were prepared by the solid-phase reaction, using sodium benzene sulfonate as a catalyst and template. Theoretical calculation of deprotonation reaction energy of glycerol and zinc chloride, bismuth nitrate was performed with the framework of DFT, and their structures were characterized by X-ray diffraction, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscope and X-ray photoelectron spectroscopy. The thermal stability of Gly-Zn and Gly-Bi for polyvinyl chloride (PVC) is discussed by TG. The results show that the deprotonation reaction of glycerol with zinc chloride or bismuth nitrate mainly occurs in the dehydrogen of secondary hydroxyl ( O sec H) and primary hydroxyl ( O prim H) of glycerol molecules, and the H of O sec H is more active than that of the O prim H. The obtained Gly-Zn and Gly-Bi have good micromorphology with the rod-like and bar-like respectively. Applied them as thermal stabilizers to PVC processing, the reaction kinetic constant (k, s À1 ) is an order of k PVC > k PVC/Gly-Zn > k PVC/Gly-Bi . After the additions of 10% Gly-Zn and 10% Gly-Bi, the thermal stability time (min) of PVC, PVC/Gly-Zn and PVC/Gly-Bi is 45, 54.43 and 71.47, respectively.
