Problems solved by technology

However, the above methods have some disadvantages. For example, the hard template method has cumbersome process steps and is not suitable for large-scale synthesis. When the hard template is removed, the shell structure of the obtained product often becomes loose or even destroyed.
However, the size uniformity of the products prepared by the soft template method is poor, and the formation process of the soft template is complicated, so it is difficult to realize large-scale preparation of hollow structure materials.

Description

Technical field [0001] The invention relates to a method for preparing a hollow ellipsoidal nickel-manganese binary sulfide, which belongs to the technical field of functional material preparation. Background technique [0002] The hollow structure materials have the advantages of low density and large specific surface area, which make them have broad application prospects in the fields of catalysis, sensing, controlled drug release and electrochemical energy storage. Therefore, the controllable synthesis of hollow structure materials has caused many The attention of researchers. As a class of electrochemical energy storage materials, transition metal sulfide semiconductors have better electrical conductivity and thermal stability than transition metal oxides, so transition metal sulfides are more promising energy storage electrode materials. Subtle structural design of electrode materials can obtain energy storage devices with better performance. Hollow structural materials hav...
