MACROPOROUS PEROVSKITE MANGANESE OXIDES WITH HIGHLY ORDERED NANO-PORES AND METHOD OF PREPARING THE SAME

摘要

The present invention relates to the macroporous manganese oxide material having ferromagnetic property and a method of preparing the same, more particularly to the macroporous ferromagnetic manganese oxide having three-dimensionally ordered nanopores, which is prepared by aligning colloidal polymer particles with an average diameter of a few hundred nanometers in 3D, infiltrating a solution of the precursor compound capable of forming manganese oxide represented by the following Chemical Formula 1 into interstices of the colloidal template and heating in an oxygen atmosphere to decompose and remove the polymer template, and a method for preparing the same: La_1-xCa_x-ySr_yMnO₃  (1) wherein 0.25x0.35 and 0y≦0.35.
