Dry reforming catalyst using metal oxide support, and method for preparing synthetic gas by using same

Abstract

The present invention relates to: a dry reforming catalyst in which an active material is impregnated on the surface of a metal oxide support, wherein the active material is surrounded by a surfactant; a method for preparing the same; and a method for preparing a synthetic gas by using the catalyst. Since the surfactant on the surface of the active material prevents sintering of the active material and a phenomenon of covering the active surface with carbon, the dry reforming catalyst exhibits high activity for a long time at a high temperature without using a noble metal, thereby being useful in the preparation of a synthesis gas.
