Abstract In terms of biocompatibility, environmental friendliness, scalability, and cost-effectiveness, green nanoparticle (NP) synthesis is a modern area nanotechnology that performs better than physical chemical methods. The utilization endophytic Penicillium oxalicum for the biogenesis silica nanoparticles goal current work. structural optical properties fungal produced were investigated utilizing transmission electron microscopy (TEM), fourier transform infrared spectroscopy (FTIR), x ray diffraction (XRD) dynamic light scattering (DLS). All parameters their interactions found to have significant effect on crystallite size, according results. average diameter size biosynthesized SiO 2 -NPs was ranged between 20 -50 nm. 28.7 nm, crystalline nature confirmed by XRD, characterization A surface plasmon resonance spectrum obtained at 280 Under UV light, Ribazol black b Crystal violet dyes photocatalytically degraded nanoparticles. highest decolorization percentage 94.1% ± 1.2% 85.1% 0.93%, respectively after 90 120 min, both crystal incubation 50.0 mg mL ─1 Furthermore, successfully used more once biodegradation regarded as its efficacy. Silica remove Co, Pb, Cd, Zn with percentages 99.9% 1.2%, 1.3%, 99.4% 1.4%, respectively. phytotoxicity test using Zea mays L seed which root length increases (28 0.35) (21 0.51) cm, when subjected tothe treated CV Ribazole effluent... conclusion, biosynthesize -NPs, showed, phytotoxicity, heavy metal bioremediation, photocatalytic activity against dye.

Construction of Fe₂O₃ Nanoparticles Decorated for a Highly Efficient Oxygen Evolution Reaction Activity

Energy & Fuels, Год журнала: 2023, Номер 37(20), С. 15976 - 15985

Fossil fuels are going out of stock as a result population and industrial growth, the uptake fossil has also affected atmosphere, causing pollution other defects. Over past few years, researchers focused on from renewable sources that unharmful to humans Earth's atmosphere. Constructing lucrative highly competent electrocatalysts is still challenging task in oxygen evolution reaction (OER) activity. In this study, we have synthesized Fe2O3 with N- S-doped reduced graphene oxide (rGO) via co-precipitation technique subsequent annealing procedure. The formation rhombohedral phase spherical nanoparticles rGO been examined. introduction not only agglomeration particles particle size but facilitated electronic structure. As result, Fe2O3/N- nanocomposite requires 250 mV attain 10 mA/cm2 Tafel slope value 115 mV/dec an alkaline medium. With benefit presence sheets, charge-transfer resistance Fe2O3/N S was lower 24.9 Ω exhibited large electrochemical surface area 110 cm2. Therefore, our findings suggest iron decorated carbon matrix could efficiently enhance OER activity accomplish water splitting.

In the current study synthesized Cobalt oxide nanoparticles (Co3O4 NPs) using Lawsonia inermis plant extract as fuel. The Co3O4 NPs were characterized UV–visible spectroscopy, DLS, FT-IR, XRD, FESEM, and EDX analysis. confirmed by XRD analysis their average size was determined DLS FESEM of cobalt obtained from found to be around 98 nm strong signals captured in images. tested on antibacterial fungal strains three concentrations viz 50, 100 170 ppm. An increase concentration shows potent antifungal activities. higher (170 ppm) showed good antimicrobial activity all bacteria fungi than lower (50 NPs. observed zone inhibition values against ranged 0.3 3.0 ppm 20 ± 0.42 mm 2.9 ppm, respectively. Among them, Staphylococcus Streptococcus aureus more zones at concentration. Meyerozyma guilliermondii strain
