Study of structural and optical properties of ZnO nanoparticles synthesized by an eco-friendly tapioca-assisted route

The photocatalytic degradation of a binary textile dyes mixture within a new configuration of loop reactor using ZnO thin film-phytotoxicity control

“…No traces of contaminants or impurities from the raw precursor are found in both samples. The same findings are reported elsewhere [47,48].…”

A Comprehensive Study on the Effect of ZnO and ZnAl2O4 Nanoparticles on the Mechanical Properties of Epoxy Coating: Tensile and Hardness

“…The obtained microstrain (ε) values for ZnO and ZnAl 2 O 4 nanoparticles are listed in Table 1. The microstrain value of the synthesized ZnO NPs is quite similar to that reported by Almeida et al for ZnO NPs, prepared by the sol-gel method (Lopes de Almeida et al, 2021). However, a lower microstrain value for ZnAl 2 O 4 NPs is obtained in this work, as compared to that reported by El-Fadl et al (El-Fadl et al, 2019), for ZnAl 2 O 4 NPs prepared via microwave combustion method.…”

Visible-Light-Responsive Photocatalytic Activity Significantly Enhanced by Active [VZn+VO+] Defects in Self-Assembled ZnO Nanoparticles

“…55 Moreover, terpenoids present in aqueous leaf extracts of Azadirachta indica and Emblica officinalis are thought to be responsible for stabilizing and capping ZnO nanoparticles. 56 Previous studies 15,51 have also shown that the shape and size of ZnO nanoparticles are mainly controlled by the Zn 2+ ion affinity of incomplete binding between two glucose molecules of cassava starch. These last findings shed light on the tuning of hydroxyl group content in this starch medium to control the size, morphology, and growth reaction rate of the oxide nanoparticles.…”

“…However, the main aspect of these alternate chelating agents that might be considered is their influence on the characteristics of the synthesized oxide nanoparticles. Researchers have proposed that the biochemical complexity at both the molecular and supramolecular levels of these biomasses is responsible for the size control and morphology of oxide nanoparticles. ,− Likewise, it has been reported that aldehydes, amides, carboxylic acids, flavones, ketones, and terpenoids have been presumably ascribed for binding to metal ions . Notably, phenolic groups of flavonoids present in the aqueous extract of Deverra tortuosa have also been reported to bind zinc ions, stabilizing them and preventing ZnO nanoparticle agglomeration in the synthesis .…”
