Abstract

The invention provides a manganese molybdate micro-nano bundle and a method for preparing the same. The method includes steps of firstly, preparing manganese acetate tetrahydrate aqueous solution with the concentration of 0.1-3 mol/L; secondly, preparing sodium molybdate dihydrate solution with the concentration of 0.05-0.2 mol/L; thirdly, mixing the manganese acetate tetrahydrate aqueous solution and the sodium molybdate dihydrate solution with each other according to a volume ratio of 1:(1-2), uniformly stirring the manganese acetate tetrahydrate aqueous solution and the sodium molybdate dihydrate solution, then pouring the manganese acetate tetrahydrate aqueous solution and the sodium molybdate dihydrate solution into a reaction kettle and carrying out sufficient hydrothermal reaction to obtain intermediate products; fourthly, placing the intermediate products in a tube furnace, calcining the intermediate products in argon atmosphere for 3-5 h, and then cooling the intermediate products until the temperatures of the intermediate products reach the room temperature to obtain the manganese molybdate micro-nano bundle. The manganese molybdate micro-nano bundle and the method have the advantages that the manganese molybdate micro-nano bundle prepared by the aid of the method has microscopic morphology of X-shaped structures and has large specific surface areas, and accordingly the electrochemical performance of manganese molybdate can be improved; the manganese molybdate micro-nano bundle is low in cost and high in purity, the method is simple, and accordingly the manganese molybdate micro-nano bundle has a potential market prospect in the field of nano-electronic devices.

Description

technical field [0001] The invention belongs to the field of preparation of inorganic micro-nano materials, in particular to a manganese molybdate micro-nano bundle and a preparation method thereof. Background technique [0002] Micronano molybdate (MMoO 4 ) due to the particularity of its crystal structure, it is widely used in optical, electrical, magnetic and other fields, and has a broad market prospect, so it has attracted the attention of many researchers, especially MnMoO 4 become the focus of research. For example, Chinese patent CN102502846A discloses a method for preparing manganese molybdate materials assembled into microrod structures by nanosheets; Chinese patent CN102154701A discloses a method for preparing manganese molybdate cobalt molybdate hierarchical heterostructure nanowires; In the preparation process, a large amount of surfactant (CTAB) needs to be added, and the preparation process is relatively complicated, and the product purity is not high.
