Abstract: Proposed is a dry reforming catalyst body composed of a perovskite crystal structure material having eluted transition elements with excellent catalytic stability. The dry reforming catalyst body includes a matrix composed of a perovskite crystal structure material comprising a first transition element and a second transition element and an eluate in which the first transition element is eluted from the matrix to the surface. The present invention provides a dry reforming catalyst including a perovskite structure material having an eluted transition element with excellent catalyst stability. The dry reforming catalyst according to one embodiment of the present invention includes a matrix comprising a perovskite structure material comprising a first transition element and a second transition element and an eluate which is the first transition element eluted from the matrix to the surface.
