Abstract:
The present invention provides a catalyst in which a reaction initiation temperature at which self-heating function is exhibited is low and which is capable of suppressing carbon accumulation even when a reaction is repeated. The catalyst of the present invention includes a CeZr-based oxide, silicon, and a catalytically active metal, wherein the CeZr-based oxide satisfies CexZryO2 (x+y=1) and the silicon satisfies molar ratios of 0.02≦Si/Zr and 0.01
