Manganomanganic oxide has a spinel structure with manganese 3 and manganese 2 occupying octahedral and tetrahedral sites of the spinel structure, respectively. Due to the special structure, the manganese oxide has the characteristics of low price, environmental friendliness, abundant reserves, good electrochemical performance in neutral/alkaline electrolyte and the like, and the mangano-manganic oxide plays a very important role in the aspects of catalysis, preparation of lithium manganate serving as a positive material of a super capacitor and a lithium ion battery, preparation of soft magnetic ferrite and the like, and is widely concerned by researchers in application;

The high valence manganese oxide method has strict technological requirements, high roasting temperature, poor physical properties of the prepared material and the like, and limits the wide application of the method. The manganese salt method has the advantages of high purity of prepared products, good activity and the like, but has the defects of by-products, high production cost, non-green and non-environmental protection. Manganese carbonate, manganese sulfate and manganese oxide are mostly used as raw materials in the manganese carbonate method, and the manganese carbonate, manganese sulfate and manganese oxide are roasted and oxidized at high temperature to generate trimanganese tetroxide, so that the preparation conditions are harsh, the specific surface area is low and the like. The manganese metal method has low technical content and easy operation, but has high production cost, uneven granularity of prepared samples, larger grain diameter and generally higher content of various impurities. In a word, the existing method for preparing the manganous-manganic oxide material has the problems of complex production process flow, insufficient product purity, poor physical and chemical activity and the like. And reports about the porous trimanganese tetroxide nano material with large specific surface area are less, and reports about the simple and rapid preparation of the porous trimanganese tetroxide nano material with large specific surface area by a one-step method are less. Therefore, how to rapidly, simply and industrially prepare the porous trimanganese tetroxide nano material with large specific surface area is particularly important.
The invention aims to provide a novel preparation method of a large-specific-surface-area porous manganous-manganic oxide nano material, and mainly solves the problems of long and complicated preparation process flow, low purity of prepared products, poor physical and chemical activity caused by large grain size of the products and the like in the conventional method, so that the method for rapidly preparing the large-specific-surface-area porous manganous-manganic oxide nano material in one step is provided for the fields of catalysis and energy storage, and the rapid development of the manganous-manganic oxide nano material in the fields is promoted.
