Abstract:
Nanopowders of magnesium aluminate spinel (MgAl2O4) were produced using a solid-state approach, involving a reaction between magnesium nitrate, aluminum nitrate, and oxalic acid. The synthesized nanomaterials' structural, morphological, and catalytic properties were examined by XRD, FTIR, TGA, SEM, EDX, BET, and TEM analyses. To evaluate their catalytic performance, the photocatalytic degradation of Rhodamine B (RhB) dye under Xenon lamp irradiation was investigated. Therefore, the combined application of photocatalysis and adsorption processes has proven to be highly effective for removing RhB from aqueous solutions. Notably, the highest removal efficiency, reaching 95% after 120 min, was obtained through photocatalytic degradation under Xe lamp irradiation.
