Abstract: The present research effectively constructed a core-shell-shell structure of Ag-TeO 3 /Fe 3 O 4 @TiO 2 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-TeO 3 /Fe 3 O 4 @TiO 2 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 minutes of radiation exposure, with MO and MB dye elimination efficiencies reaching 99.2% and 98.2%, correspondingly. Following five attempts of regenerating Ag-TeO 3 /Fe 3 O 4 @TiO 2 demonstrated 96.96% MO and MB dye elimination performance.
