Controlled Synthesis and Enhanced Photocatalytic Performance of MgAl2O4 Spinel Nanopowders for Environmental Applications

ChemistryOpen, Volume 15, Issue 8, August 2026.
A simple solid‐state route was employed to synthesize MgAl2O4 spinel nanopowders with high photocatalytic efficiency. The obtained nanomaterial achieved 95% degradation of Rhodamine B under Xe lamp irradiation, demonstrating its potential as an efficient photocatalyst for wastewater purification. Nanopowders of magnesium aluminate spinel (MgAl2O4) were
