METHOD FOR PREPARING FERROFERRIC OXIDE HOLLOW SPHERES

摘要

The present invention relates to a method for preparing ferroferric oxide hollow spheres. The method comprises the following steps: mixing and dissolving a trivalent iron source in a solvothermal reaction medium to form a first mixed solution, wherein the solvothermal reaction medium comprises water and an organic solvent; adding a carbohydrate reducer into the first mixed solution for mixing and dissolving, so as to form a second mixed solution, and performing a solvothermal reaction for the second mixed solution so as to obtain the reaction product of ferroferric oxide hollow spheres.
