Large-pore mesoporous Mn3O4 crystals derived from metal–organic frameworks

Abstract

The large-pore mesoporous Mn3O4 crystals with tunable morphologies, size and porosities were synthesized via the conversion of metal-organic frameworks, which were fabricated by utilizing the nanostructural organizations of ionic liquid-water mixtures as templates. Mn3O4 showed high catalytic activity for the degradation of methyl blue in the wastewater treatment.
