Magnetized retrieve of Ag–TeO3/Fe3O4@TiO2 hybrid nanocomposites for optical, kinetically, half-life period and its photocatalytic assessment of methylene blue and methyl orange dyes

Abstract

The present research effectively constructed a core-shell-shell structure of Ag–TeO₃/Fe₃O₄@TiO₂ utilizing Capsicum frutescence extract, which is both magnetized highly recoverable. The catalyst was applied to photo catalytically degrade the colorants methyl orange (MO) and methylene blue (MB). The catalyst's function was further examined using XRD, FTIR, SEM, TEM/HRTEM, VSM, BET isotherm and UV–Visible spectroscopic analysis. Thus, Ag–TeO₃/Fe₃O₄@TiO₂ exhibited magnetized characteristics, including a saturation magnetic of 51.9 emu/g and a bandwidth value of 2.5 eV and half life period of 91.9min⁻¹. The photocatalytic breaking down of MO and MB dyes mirrored the Langmuir-Hinshelwood pattern. Breakdown could be observed at the MO and MB dyes after 45 and 50 min of radiation exposure, with MO and MB dye elimination efficiencies reaching 99.2 % and 98.2 %, correspondingly. Following five attempts of regenerating Ag–TeO₃/Fe₃O₄@TiO₂ demonstrated 96.96 % MO and MB dye elimination performance.
