wallpapers News 2021-12-30
Manganese ions usually exist in three valence states, Mn2+, ‚Mn3+ and Mn4+. Corresponding oxides are MnO, MnO2, Manganese Oxide Mn2O3, and Mn3O4. Among them, Manganese Oxide Mn2O3 is a widely used material in catalysis, electricity, and magnetism. Nano-scale Manganese Oxide Mn2O3 materials have good ion exchange and molecular adsorption, electrochemical, catalytic, and magnetic properties. Compared with bulk materials, it has phenomena such as enhanced surface magnetic moment, enhanced surface magnetic anisotropy, step effect, and spin reorientation. As an important semiconductor and catalyst material, Manganese Oxide Mn2O3 has attracted more and more interest and attention. In the study of reducing environmental pollution and decomposing N2O, it is found that the catalytic activity of Manganese Oxide Mn2O3 is significantly better than other manganese oxides.
In the preparation of semiconductor materials, it is used to remove organic matter from the exhaust gas, and it can also be used to improve the thermal stability of piezoelectric ceramics. In addition, Manganese Oxide Mn2O3 is an amphoteric oxide, which can be reacted with LiOH to synthesize the LiMn2O4 spinel compound. It is one of the promising materials in the positive electrode active material of lithium-ion batteries. And it has important applications in the preparation of soft magnetic material manganese zinc ferrite. Nanometer Manganese Oxide Mn2O3 has a larger specific surface area and activity than micron Manganese Oxide Mn2O3, which can greatly improve its efficiency in decomposing CO and NOx and improve its magnetic properties. In addition, it can also be used as a catalytic material for oxygen storage, so the preparation of nano-Manganese Oxide Mn2O3 materials is of great significance.
So far, people have used the hydrothermal oxidation method, supercritical fluid drying method, chemical liquid-phase precipitation method, liquid-phase catalysis method, hydrothermal-pyrolysis method, liquid-phase catalysis method, electrostatic spinning, and other methods to prepare various morphologies. Manganese Oxide Mn2O3. Manganese Oxide Mn2O3 nanoparticles, nanowires, nanorods, etc. have been successfully prepared. Because Manganese Oxide Mn2O3 nanofibers have a large specific surface area, they will have a wider range of applications in various fields.
