Abstract

The synthesis of ordered mesoporous Mn₂O₃ and Mn ₃O₄ with highly crystalline walls has been demonstrated. An aqueous solution of a Mn²⁺ salt was impregnated into the mesoporous silica, KIT-6, with a 3D pore structure by a bi-solvent method. Drying and heating at 600°C converted the precursor to Mn₂O ₃. Ordered mesoporous Mn₃O₄ with crystalline walls was synthesized by first producing highly ordered mesoporous Mn ₂O₃, then reducing it to form highly crystalline Mn ₃O₄, while retaining the ordered pore structure. The magnetic properties of mesoporous Mn₂O₃ and Mn ₃O₄ were characterized by SQUID measurements.
