Abstract
A hierarchical porous honeycombed nickel oxide microsphere and a preparation method thereof are disclosed. The method includes mixing nickel sulfate hexahydrate, urea, water and glycerol, to obtain a mixed solution; subjecting the mixed solution to a hydrothermal reaction, to obtain a precursor; and calcining the precursor, to obtain the hierarchical porous honeycombed nickel oxide microspheres.
