Highly active amorphous alloy catalysts for decomposition of flons to hydrofluoric acid, hydrochloric acid and carbon dioxide by the reaction with water, consisting of at least one element selected from the group of Ni and Co, at least one element selected from the group of Nb, Ta, Ti and Zr which are effective for formation of the amorphous structure by coexisting with at least one element selected from the group of Ni and Co, and at least one element selected from the group of Ru, Rh, Pd, Ir and Pt effective for the high catalytic activity, the alloys being activated by immersion into hydrofluoric acids.
