PROBLEM TO BE SOLVED: To provide a functional oxide which can be used as various functional materials such as ion superconductors, catalysts, etc. and can be easily manufactured and handled; and a method for manufacturing a functional oxide capable of easily manufacturing this functional oxide.SOLUTION: A functional oxide 10 includes: a metal oxide 11 having a perovskite-type crystal structure; and FePt nanoparticles 12 dispersed within the metal oxide 11. The metal oxide 11 is stable within a reducing atmosphere and is capable of solid-solubilizing Fe and Pt within an oxidative atmosphere. The metal oxide consists of A(M, Fe)O(where A=Ca, Sr, Ba; M=Ti, Zr; 0≤y<3) or Ln(M, Fe)O(where Ln=La, Ce, Pr, Nd, Sm; M=Al, Ga, Sc; 0≤y<3). The functional oxide 10 can, for example, be used not only as ion superconductors, catalysts, etc. but also as oxygen filter materials, etc. |
