PURPOSE: A production method of metal oxide is provided to produce the metal oxide on the surface of a metal porous body in the uniform density by using the characteristics of an amorphous allow porous body. CONSTITUTION: A production method of metal oxide using a metal porous body comprises the following steps: providing amorphous alloy powder (100); sintering the amorphous alloy powder to obtain an amorphous alloy porous body (200); and forming the metal oxide on the surface of the amorphous alloy porous body (300). The amorphous alloy porous body formation process is performed by an electro discharge sintering method. The metal oxide formation process is performed by a hydrothermal synthesis method. The metal oxide is formed on the surface of the amorphous alloy porous body by the oxidation of metal, or by using the metal as a catalyst. The amorphous alloy powder is Zr41.2Ti13.8Cu12.5Ni10Be22.5.

Abstract:
The present invention provides a functional material including metal oxide and a method for preparing the same. The method for forming the functional material includes forming a porous supporter with multiple pores by selectively etching at least one phase among metal alloys of two or more phases. The metal oxide is formed on the surface of the porous supporter exposed to the pores. The surface area of the porous supporter can be expanded by selectively removing at least one phase among the metal alloys. Also, the metal oxide is formed on the surface of the metal alloy porous supporter to give functionality to the material.
