Abstract: The present invention relates to a method for preparing a metal catalyst (Ni, Co, etc.)-supported porous silicon carbide structure having meso- to macro-sized pores, high porosity and superior mechanical properties. Unlike the existing method wherein a porous silicon carbide structure is prepared and then the metal catalyst is infiltrated therein, the preparation of the porous silicon carbide structure and the supporting of the metal catalyst occur at the same time by the mixing metal catalyst material and starting materials. As a result, the metal catalyst is distributed uniformly in the porous silicon carbide structure and it is possible to locate a desired amount of the metal catalyst inside the porous silicon carbide structure.
