PURPOSE:To obtain a catalyst having heat resistance and good in the utilization efficiency of a catalytic metal, by a method wherein a nonwoven fabric comprising a heat resistant fiber based on silica or alumina is used as a carrier and a catalytic coating is formed on the surface thereof. CONSTITUTION:As a catalyst for treating various gases. a catalytic metal is adhered on the surface of a carrier constituted of a nonwoven fabric comprising a heat resistant fiber based on silica or alumina to form a catalytic coating. Because thus obtained catalyst has strength or elasticity and the density thereof can be freely selected, it is good in capacity and the catalytic metal is used effectively. |
