Preparation method and application of hollow porous rod-like Mn3O4-Co nano material

The invention discloses a preparation method of a hollow porous rod-shaped Mn3O4-Co nano material and application of the hollow porous rod-shaped Mn3O4-Co nano material. A rod-like Mn-BTC MOF precursor is prepared through a simple coprecipitation method, cobalt is loaded on the surface of MOF through an impregnation method, and then the hollow porous rod-like Mn3O4-Co nano material is obtained through centrifugation, washing, drying and calcination. The prepared hollow porous rod-shaped Mn3O4-Co nano material has more oxygen vacancies and higher surface lattice oxygen activity, HMF can be efficiently and selectively oxidized into FDCA, the FDCA selectivity within 2 hours is as high as 85.49%, and the hollow porous rod-shaped Mn3O4-Co nano material has good stability. The hollow porous rod-like Mn3O4-Co nano material is prepared by taking Mn-BTC MOF as a precursor, and the preparation method has the characteristics of high economic benefit, simple preparation process and capability of realizing large-scale ind
