Environmentally Friendly Synthesis, Antibacterial Activity, and Photocatalytic Performance of AG Nanoparticles Made from Leucaena Leucocephala Leaves Extract

Abstract

The leaf extract of the plant Leucaena leucocephala was used in this research to synthesize environmentally-friendly nanotechnologies. This environmentally friendly procedure is completely safe and non-toxic. The approach is cost-effective, simple to use, and effective, and the attributes of the resultant compounds can be regulated. For example, the Ag compound can be controlled using the same plant extract and reaction. The findings and properties of these nanoparticles were investigated using a variety of techniques, including field emission-scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and atomic force microscopy (AFM). EDX-mapping was also used to explore the analysis of Ag NPs. Electron microscopy investigations with transmission electron microscopes (TEM). which indicated the presence of Ag in the compound and their effective degradation. The produced chemical was tested for effectiveness using bacteria. The antibacterial activity of Ag NPs was investigated utilizing two different species of bacteria, Gram-negative E. Coli and Gram-positive S.aureus e.In addition, the photocatalytic capacity of Ag NPs was discovered through the photodegradation of dyes, as the rhodamine B dye was decomposed at a 78% percent rate. The effect of the catalyst amount and amounts (0.2,0.4,0.6,0.8,1, 1.2,1.4,1.6g/L) were investigated, with the best weight being 1gm and the dye concentration being 10ppm. Water and oxygen are converted to.OH radical with very powerful oxidation by receivers for electrons as well as those electrons and free holes.

Nanoremediation and Antioxidant Potential of Biogenic Silver Nanoparticles Synthesized Using Leucena’s Leaves, Stem, and Fruits

“…By carrying out a different synthesis protocol time (30 min) with a different proportion of silver nitrate to extract (0.5 g of AgNO 3 for 50 mL of extract), Hazim and collaborators obtained a different silver nanoparticle. Presenting an average size of 35 nm (smaller than the ones synthesized in this work) and depending on a reactor with a 200 W visible light source (produced by a Xenon lamp), the nanoparticle, at 1000 ppm, could remove approximately 78% of the synthetic dye used in the experiments [36]. With a different ratio of Leucena leaves to distilled water (5 g to 1000 mL), extracted overnight, Raju and collaborators also obtained a plant extract for AgNPs synthesis.…”

“…When it comes to acting in the nanoremediation of pollution caused by dyes, this plant has already provided material for the production of AgNPs capable of performing this task. However, these nanomaterials depended upon direct sunlight or special lamps to perform this action efficiently [36,37]. Some of these AgNPs also exhibited antioxidant potential [37].…”
