Abstract: Provided are: a dry reforming catalyst, in which a noble metal (M) is doped in a nickel yttria stabilized zirconia complex (Ni/YSZ) and an alloy (M-Ni alloy) of the noble metal (M) and nickel is formed at Ni sites on a surface of the nickel yttria stabilized zircona (YSZ); a method for producing the dry reforming catalyst using the noble metal/glucose; and a method for performing dry reforming using the catalyst. The present invention can exhibit a significantly higher dry reforming activity as compared with Ni/YSZ catalysts. Furthermore, the present invention can have an improved long-term performance by suppressing or preventing the deterioration. Furthermore, the preparing method is useful in performing the alloying of noble metal with Ni at Ni sites on the Ni/YSZ surface and can simplify the preparing process, and thus is suitable in mass production.
