<p>This study aims to synthesize magnetically recoverable AgFe₂O₄/TiO₂ nanocomposites and evaluate their photocatalytic performance for the degradation of methylene blue (MB) under UV irradiation. The nanocomposites were prepared via a combined sol–gel and solvothermal route and characterized using XRD, SEM, TEM, HRTEM, UV–Vis DRS, PL, XPS, and VSM analyses. XRD confirmed the coexistence of anatase TiO₂ (≈10 nm) and spinel AgFe₂O₄ (≈17 nm). SEM and TEM images revealed quasi-spherical particles (25–42 nm) with uniform dispersion. UV–Vis diffuse reflectance analysis showed a red-shifted absorption edge and a reduced band gap (2.40 eV) compared with pristine TiO₂ (3.2 eV). Photoluminescence spectra exhibited significant emission quenching, indicating suppressed electron–hole recombination due to the heterojunction structure. XPS analysis confirmed the presence of Ag⁰/Ag⁺, Fe²⁺/Fe³⁺, and Ti⁴⁺ species, suggesting effective interfacial charge transfer. Magnetic measurements revealed a saturation magnetization of 19 emu g⁻¹, demonstrating magnetic recoverability of the composite. Photocatalytic experiments showed negligible dye adsorption in the dark, while approximately 85% of MB was degraded within 120 min under UV irradiation. Kinetic analysis indicated that the degradation process follows pseudo-first-order kinetics. Radical scavenger experiments identified photogenerated holes (h⁺) and superoxide radicals (•O₂^⁻) as the dominant reactive species responsible for dye degradation. In addition, the photocatalyst retained more than 80% of its activity after ten reuse cycles, confirming its stability and reusability. These results demonstrate that the AgFe₂O₄/TiO₂ nanocomposite is an efficient, magnetically separable, and reusable photocatalyst with promising potential for wastewater treatment applications.</p><p></p>
