Disclosed are a noble metal-integrated catalyst and a preparation method therefor. The noble metal-integrated catalyst comprises a carrier and a noble metal as an active component, wherein the carrier is a cordierite honeycomb ceramic with high cell density, and the active component is a noble metal supported on rare earth metal oxide and transition metal oxide. The noble metal-integrated catalyst has good reactivity and stability, and the active component is uniformly distributed with the load controllable. The present invention solves the problems of low bonding strength between the cordierite honeycomb ceramic carrier and the active component and blockage of carrier channels by the active component, enables preparation of the active component and the deposition process to be completed in one step, and significantly simplifies the preparation process of the noble metal-integrated catalyst.
