The Doping of Al3+ at the Tetrahedral Site of Spinel Mn3O4 for Electrocatalytic Water Oxidation
Year: 2024
Type: article
Abstract: Spinel oxides have attracted much attention for electrocatalytic water oxidation. Specially, the Mn‐based spinel structures merits fundamental investigation, as Mn is involved in water oxidation in natural photosynthesis. Herein, Al‐doped Mn3O4 spinel electrocatalyst was prepared for water oxidation. The Al cations selectively occupy the tetrahedral sites of Mn3O4 spinel structure, leaving Mn(III) at the catalytically critical octahedral sites. The substitution of Al3+ regulated the electronic structure of Mn3O4, induced lattice distortion and produced higher concentration of oxygen vacancy to promote the water oxidation performance.
