Applied Organometallic Chemistry, Journal Year: 2025, Volume and Issue: 39(2)

Published: Jan. 14, 2025

ABSTRACT Ferrite magnetic materials have emerged as capable in engineering, research, and medicine because of their exclusive fascinating properties obtained from a variety synthesis techniques. These ferrites are significant commercial products, biomedical applications. Green methods for ferrite nanocomposites nanoparticles becoming increasingly popular due to usefulness range industries, environmental, medicinal remediation. (MFe 2 O 4 , where M = Ni, Cu, Mg, Co, Zn, Mn) recently gained popularity many uses biological, chemical interactions. This review covers the most recent investigations over last few years on green‐synthesized nanoparticles, containing nanocomposites, more elements, with focus microorganism‐mediated plant‐based processes. The surface features synthesized green discussed, is potential sensors, energy, water treatment, antibacterial activity, heavy metal removal article presents an inclusive overview ferrites, including research advances findings. To fully realize promise nanoferrites several fields, thorough understanding manufacturing, properties, applications essential. Green‐synthesized chosen improved control particle size shape, lower cost, decreased toxicity, environmental friendliness, all which preserve that better than those conventionally making them sustainable choice

Microscopy Research and Technique, Journal Year: 2024, Volume and Issue: 88(1), P. 73 - 91

Published: Aug. 27, 2024

Abstract As a result of their unique and novel properties, nanocomposites have found applications in wide variety fields. The purpose this study is to demonstrate the ability synthesize nanoparticles consisting zinc oxide (ZnO) graphene (GO) via sol–gel techniques. An x‐ray diffractometer (XRD) as well UV–visible spectrometer were used determine crystalline optical characteristics prepared samples. A hexagonal wurtzite crystal structure was observed both pure ZnO those that contain GO based on XRD results. It estimated average crystallite size broadening lines. In comparison with ZnO, antimicrobial properties enhanced when incorporated ZnO. addition, experiments absorption edge indicated presence red shift incorporation GO. When quantitative amounts, bandgap value decreased. FTIR spectra exhibit band at 486 cm −1 , which confirms Zn‐O stretching SEM images reveal random pattern structural features surface According EDX spectrum, doped 61%–64% 32%–34% oxygen, respectively. annealed higher temperature, NPs produced more H 2 narrower than before annealing. methyl blue (MB) an example organic compound order investigate potential photocatalytic addition DPPH assays, tested for scavenge free radicals.

ABSTRACT The semiconducting nature of CeFeO 3 /CeO 2 /Fe O nanocomposite has permitted the degradation organic toxic dye methylene blue under irradiation ultraviolet and visible light portions solar radiation. Fullprof‐assisted Rietveld refinement analysis, performed using Match software, revealed orthorhombic . In addition, in synthesized material, cubic phase byproduct CeO was found due to highly oxidizing cerium element. This occurred 6 min microwave because microwave‐assisted technique offered random distribution heating during supply 800‐W power for 30 s, followed by 12 cycles. Additionally, presence Fe also confirmed through software‐assisted analysis matching. During synthesis, a certain portion experienced overheating, leading transformation from into unit cell compositions , were sample material with 35.54%, 52.43%, 12.03%, respectively. appearance fingerprint absorption region FTIR spectrum around 577.36 535.38 cm −1 further similarity these values (577.36 ) those obtained calculated substituting refined bond length parameters. fourth step process thermal curve (TGA) oxidation process, which led destruction phase, causing two byproducts (CeO ). an observable weight gain, is observed (TGA). A cyclic voltammetry study (the experimentally measured current–voltage characteristic curve) slightly distorted semirectangular CV curves, confirming pseudo‐capacitive behavior composite.
