Multivalent manganese oxide filler, preparation method therefor, and application thereof

Abstract

The present invention discloses a multivalent manganese oxide filler, a preparation method therefor, and an application thereof. The preparation method comprises the following steps: step 1: adding a Eucalyptus robusta Smith leaf extract into a potassium permanganate solution for oxidation reaction, and stirring to finally form a suspension; step 2: sequentially filtering and drying the suspension in the step 1 to obtain a sintering precursor; and step 3: sintering the sintering precursor to obtain the multivalent manganese oxide filler. According to the present invention, through the combination of oxidation reaction and sintering reaction in the present invention, the multivalent manganese oxide filler containing manganese (II), manganese (III) and manganese (IV) is prepared, and the filler is loose and porous; in addition, the oxidation reaction and the sintering reaction are combined in the present invention, so that the process difficulty of preparing the multivalent manganese oxide is reduced.
