Outline of Final Research Achievements

Amorphous manganese oxide nanospheres form by standing potassium permanganate aqueous ammonia solution. We successfully obtained metal ions or inorganic materials-amorphous manganese oxide composite nanoparticles by dissolving or dispersing beforehand metal ions or inorganic materials. The two types of composite amorphous materials converted to metal-manganese composite oxides or inorganic materials-manganese oxide composites after calcination and they show high chemical reactivity towards oxidative decomposition of organic dyes. Additionally, we developed synthetic method of shape-controlled manganese oxides and copper oxides and various inorganic nanomaterials.
