A method for preparing a metal oxide catalyst with a three-dimensional structure on a surface of a metallic or ceramic support by adhering active carbon particles onto the surface of the support using pitch as a binder, carbonizing the binder, absorbing metal oxides such as metal complex, metal alkoxide, metal chloride and metal ammonium compound into the active carbon particles, and drying and fixing the metal oxides into pores of the active carbon particles is provided. A method for preparing a metal oxide catalyst with a three-dimensional structure on a surface of a metallic or ceramic support comprises: a process of adhering active carbon particles onto the surface of the metallic or ceramic support using pitch as a binder; a process of carbonizing the binder in a heating furnace which is maintained by one or more inert gases of nitrogen, helium, argon and water vapor to fix the active carbon particles onto the surface of the metallic or ceramic support; a drying process of absorbing a solution into which at least one salt or organometallic compound type metal oxide precursor is dissolved into the active carbon particles adhered onto the surface of the metallic or ceramic support, and removing a solvent from the solution to fix metal oxides onto the surface of the metallic or ceramic support; and a process of removing carbon dioxide by performing the combustion reaction of the active carbon particles on the surface of the metallic or ceramic support in a combustion furnace which is held in a temperature range from 300 to 1000 deg.C. |
