  • Publication number: 20080132409
    Abstract: Herein is provided a fibrous catalyst having a catalytic layer containing particles comprising ceria CeO2, with an average particle size of 1 nm to 1 ?m. The layer is coated on the surface of a ceramic fiber. Accordingly, flexibility of the surface of the catalytic layer is improved due to the decreased interaction between the particles due to their minute size. Because flexibility is improved, vibration and deformation does not deteriorate the layer, and as such, the peeling-resistance property is improved.
