“…For the reduction of Fe 3+ ions, equal volume of aqueous plant extract was added slowly to aqueous ferric chloride solution and vortexed (Vortex Genie 2, scientific industries, USA) for 3 min at room temperature. The formation of iron nanoparticles was indicated by the colour change of solution from light yellow to black [27]. The black precipitate was obtained through centrifugation at 6000 rpm (Hettich zentrifugen, Andreas Hettich group, Tuttlingen, Germany) and washed several times with 1:1 ethanol and water followed by drying at 60 °C in the oven [49].…”

Metallic nanoparticles synthesized using aqueous plant extracts are environment-friendly, biocompatible, and highly stable. The aim of this study was to synthesize iron nanoparticles using aqueous Ageratum conyzoides extracts and evaluating their antimicrobial and photocatalytic properties. The particles were analysed using UV-Vis spectrophotometer, FT-IR Spectrophotometer, X-ray diffractometer and Scanning electron microscope. GC-MS profile of the extracts revealed presence of secondary metabolites which were further quantified to determine the total phenolic and total flavonoids content of the extracts. The antibacterial activity of the plant extract and the synthesized iron oxide nanoparticles was evaluated against five microorganisms using agar well diffusion method. Iron nanoparticles synthesized in a one step process observed using visible spectra and the functional groups present such as C=O were identified from IR spectrum. SEM-EDX profile identified presence of iron, oxygen, chlorine, calcium in the particles while XRD data revealed the particles synthesized were composed oxides of iron which had moderate activity against the selected microorganisms as compared to the antibiotic ciprofloxacin. The particles were able to photocatalytic degrade methylene blue with a degradation efficiency of 92%. The results obtained in this study confirms that Ageratum conyzoides can play an important role in the bioreduction of Fe ions to FeNPs which have moderate activity against microorganisms and can act as photocatalyst to degrade methylene blue.

“…56 These core-shell structures possess multifunctional properties through integrating two different materials into one entity. Therefore, they are widely studied and used in various applications such as catalysis, [58][59][60][61][62][63] electronics, 64,65 biomedical applications, [66][67][68] photoluminescence, [69][70][71][72] sensors, 73 piezo-electrics, 74,75 magnetic applications, [76][77][78] energy storage, 79,80 solar cells, [81][82][83] and CO 2 capture. [84][85][86] Core-shell materials offer additional electronic modifications due to band-edge alignment at the interface between the core and shell.…”

Metallic nanoparticles that have photocatalytic activity can be synthesized using aqueous plant extracts. The aim of this study was to synthesize iron nanoparticles using Lantana trifolia extracts and to evaluate their ability to degrade Congo red dye. The nanoparticles were characterized using UV-Vis spectrophotometer (UV-Vis), Fourier transform infrared spectrophotometer, wide angle X-ray diffractometer, dynamic light scattering, transmission electron microscopy (TEM), and thermal gravimetric analyzer to determine the functional groups, thermal properties, crystalline phases and diameter distribution of the particles. Cyclic voltammetry was used to evaluate the redox potential of the extracts while photocatalytic activity of the nanoparticles was evaluated using a UV-Vis spectrophotometer. Functional groups analysis revealed presence of secondary metabolites having OH and C=C groups while a redox potential of + 0.3 V was an indication that the extracts can reduce iron. The presence of sharp peaks at 2θ values of 19.87°, 20.22°, 22.88°, 28.81°, 32.73°, 35.32°, 38.45°, 40.23° and 41.08° correspond to cubic crystal system of iron nanoparticles while particle aggregation was observed on TEM micrographs which also indicated that they were less than 200 nm. In the presence of H 2 O 2 , the nanoparticles catalyzed degradation of Congo red dye in a first order reaction that was temperature dependent. In conclusion, secondary metabolites in L. trifolia can reduce metallic ion to iron nanoparticles which can degrade Congo red dye.
