“…Generally, a chemical scavenger that is selective to a speci c radical specie should possess the following properties: a (i) sufficient (≥ 3 order of magnitude) difference in the reactivities between various species present, (ii) inert to other coexisting oxidants such as PMS, and (iii) not interfering the catalytic activity or causing deactivation of catalyst active sites [33]. Given the lower reactivity of TBA towards SO 4 •-(k = 4.0 × 10 5 M -1 s -1 ) compared to its reactivity towards • OH (k = 6.0 × 10 8 M -1 s -1 ) [34,35] which satis es the properties of a selective chemical scavenger, TBA was used as the • OH in this study. As presented in Fig.…”

Herein, mixed–metal nanocomposite catalysts with various compositions (CoFe2O4/xFe2O3; x = 0, 0.25, 0.50, 0.75 and 1) were successfully fabricated by a co–precipitation method. The composition and morphology of the catalyst were systematically characterized. The catalyst with the highest Co content (CoFe2O4), exhibited the greatest efficiency for the acid orange 7 (AO7) degradation via peroxymonosulfate (PMS) activation. The effects of several experimental parameters including pH, CoFe2O4 loading, and PMS dosage on AO7 degradation were studied, and the catalytic activity was found to increase with the mentioned parameters. Moreover, CoFe2O4 displayed adequate reusability and was able to degrade AO7 for at least four consecutive cycles. In addition, the total organic carbon (TOC) removal of CoFe2O4 was determined while the catalyst stability was observed from the metal leaching in the treated solution. Furthermore, the magnetism of CoFe2O4 provides facile separation of the catalyst from the treated solution. Sulfate radicals (SO4•–) were identified as the main reactive species responsible for AO7 degradation.

Bismuth ferrite nanoparticles decorated with multi-walled carbon nanotube nanoparticles were prepared using a Sol-Gel soft chemical approach technique. The synthesis was carried out under green conditions using high-quality acetate precursor salts. The carbon nanotubes were obtained from the germination of chippikalan oyster mushroom. The successful synthesis of the nanoparticles was confirmed by several characterization techniques, including structural, morphological, and optical studies. The nanoparticles were capped with various phytochemicals found in the leaf extract of Murrayakoenigii and Azadirachta indica. The objective of the study was to evaluate the impact of biogenic Bismuth ferrite oxide multiwalled carbon nanotube nanoparticles on the growth of oyster mushrooms. The plant growth parameters such as stem length, breadth, germination spores percentage, spores germination rate, and mean daily germination were observed.
