The green fabrication of nanoparticles (NPs) by using plants as reducing and capping agents involves energy efficient, less toxic, safer and simpler pathways. These pathways have been related to the rational use of numerous substances in fabrication of NPs and synthetic strategies, which have been mainly discussed in this article. The subject matter of this review is to discuss how a chemist can follow the green chemistry principles in terms of selection of substances and protocols used for NPs fabrication. Furthermore, it describes how a researcher can modify the physical properties of NPs by varying the reaction conditions. In short, this review article provides a scheme for the synthesis of NPs from selection of suitable plant to characterization of formed NPs by employing green chemistry.

Magnetoliposomes containing magnetite, soy lecithin, stigmasterol, and beta-sitosterol of the mean size minor than 160 nm were obtained by a scalable and green process using autoclave and sonication without organic solvents. The formation, size of the liposome, linkage, and encapsulation of the magnetite were evaluated by Cryo-TEM. The stability of magnetoliposomes after storage for 6 months at 4 °C was improved by liposome size, the ability of soy lecithin to preserve the magnetite phase against oxidation, pH, polydispersity index, and zeta potential.

The increasing economic damage caused by terrestrial gastropods, especially the Monacha cartusiana (M. cartusiana) land snail, to the agricultural sector requires a diligent and continuous search for new materials and alternatives for the control operations. In this piece of work, a magnetically separable molluscicide with high effectiveness green Barium-Cerium-Copper ferrite/TiO (Ba-Ce-CuFO/TiO) nanocomposite was greenly prepared using Eichhornia plant aqueous extract and characterized using different techniques.

Seawater electrolysis is an ideal technology for obtaining clean energy-green hydrogen. Developing efficient bifunctional catalysts is crucial for hydrogen production through direct seawater electrolysis. Currently, metal substrates loaded with active catalysts are widely employed as electrodes for seawater electrolysis.

In this research, with the Green Chemistry approach, to load more sulfonic acid active sites on catalyst surfaces, a nanocomposite material based on core-shell magnetite coated with vinyl silane and a sulfonated polymeric brush-like structure is designed and synthesized as a new class of efficient solid acid catalysts, referred to as FeO@VS-APS brush solid acid. The synthesized catalyst was comprehensively characterized by a range of instrumental techniques, including XRD, SEM, TEM, FT-IR, EDX, TGA, and VSM. The activity of the catalyst was evaluated in Biginelli, Strecker, and esterification reactions.

Herein, a novel amine-functionalized magnetic resorcinol-formaldehyde with a core-shell structure (FeO@RF/Pr-NH) is prepared through the chemical immobilization of (3-aminopropyl)trimethoxysilane over FeO@RF composite. Characterization through FT-IR, EDX, PXRD, and TGA confirmed successful surface modification while preserving the crystalline structure of FeO. The VSM analysis demonstrated excellent superparamagnetic properties, and SEM and TEM images revealed spherical particles for the designed nanocatalyst.
