| Abstract Scope |
This study describes the synthesis of a novel equi-atomic high-entropy oxide, (Mn0.6Cr0.6Co0.6Al0.6Li0.6)O4, with a spinel structure using the sol-gel method followed by calcination at 700°C. Characterization via XRD and TEM confirmed the formation of nanocomposite structures with desired phase compositions. Magnetic properties were investigated through M vs. H loops at 300 K and 5 K, showing soft magnetic behavior with a coercivity (HC) of 38 Oe at 300 K, transitioning to hard magnetic behavior with HC of 2524 Oe at 5 K. XPS revealed diverse oxidation states among the constituent elements. Further explored the material's synergistic properties, such as DRS-UV and Mott-Schottky measurements, demonstrated the oxide's catalytic potential to degrade organic dyes via interactions with reactive oxygen species generated through Fenton-like reactions with H2O2, photon absorption, or photo-Fenton mechanism. This study highlights the multifaceted properties of high-entropy oxides, integrating magnetic behavior and catalytic activity in a single-phase structure. |
