The invention relates to a nickel oxide microsphere, which is a spherical structure with a hollow interior. The spherical shell is assembled from various nickel oxide nanosheets, and the plane where the nickel oxide nanosheet is located is consistent with the thickness direction of the spherical shell of the nickel oxide hollow microsphere. , there are pores on the spherical shell, the pores are formed by the area enclosed between adjacent nanosheets, the pore cross-section of the pores is polygonal, and the pore cross-sectional size of the pores gradually increases with the direction a, and the direction a is the inner side of the spherical shell pointing to the spherical shell In the outer direction, the surface of the nickel oxide nanosheets has a mesoporous structure. The above-mentioned nickel oxide microspheres have a unique tertiary pore structure with high specific surface area and porosity. |
