Fundamental Research on Functionally Graded Material

Characteristic of Optical Catalyst of Titanium

Abstract

The purpose of this study is to remove the nitrogen oxide from the surface of the material. The nitrogen oxide is one of important problems in the air pollution. The nitrogen oxide is removed by using the oxidation action of the material. The optical catalyst material has the oxidation action on the surface of the material. Titanium is of great use for the optical catalyst material. The functionally graded materials(FGMS) have been developed in Japan. In this paper, these constituents of materials are distributed in continuous gradation in order to design using a combination of titanium oxide and Korean kaolin.
