People have begun to make polymer containing catalysts for dioxin decomposition. To make high functional polymer containing catalysts for dioxin decomposition, catalysts have very small size and are colorless for their various application. The objectives of this study are to prepare colorless, highly active, nano-sized catalysts for the incorporation into polymeric materials. Finally we want to remove dioxin during incineration of these polymers. color-masked Fe nano-catalysts with TiO2 nano particles have showed better activity comparing individual Fe or TiO2. During incineration of catalyst –embdded PE, most of noxious gas was successfully removed. By changing catalytic materials embedded inside polymer, we can control physical properties such as; transmittance, tensile strength, etc.
