Abstract

Provided are a composite structure, in which metal nanoparticle-perovskite oxide is bound to metal oxide supports (i.e., sensing materials), and a preparation method thereof. The composite structure has improved durability, in which metal nanoparticles uniform in size are evenly distributed on the surface of perovskite oxide. Provided is also a high-performance gas sensor having excellent target gas detection performances by including the composite structure.
