TITLE: Amorphous alloy catalysts for conversion of exhaust gases to harmless gases ABSTRACT The present invention relates to amorphous alloy catalysts for conversion of exhaust gases to harmless gases, and technically includes: (1) Catalysts for conversion of exhaust gases to harmless gases, comprising an amorphous alloy consisting of 20 - 70 at% of at least one element selected from Nb and Ta, 0.5 - 20 at% of at least one element selected from Ru, Pd, Rh, Pt and Ir, with the balance being substantially at least one element selected from Ni and Co, having been subjected to activation treatment by immersion in hydrofluoric acid. (2) Catalysts for conversion of exhaust gases to harmless gases, comprising an amorphous alloy consisting of 20 - 80 at% of at least one element selected from Ti and Zr, 0.5 - 20 at% of at least one element selected from Ru, Pd, Rh, Pt and Ir, with the balance being substantially 10 at% of at least one element selected from Ni and Co, having been subjected to activation treatment by immersion in hydrofluoric acid. (3) Catalysts for conversion of exhaust gases to harmless gases, comprising an amorphous alloy consisting of at most 70 at% of at least one element selected from Nb and Ta, and 20 - 80 at% in the sum of at least one element selected from Nb and Ta and at least one element selected from Ti and Zr, 0.5 - 20 at% of at least one more element selected from Ru, Pd, Rh, Pt and Ir, with the balance being substantially at least 10 at% of at least one element selected from Ni and Co, having been subjected to activation treatment by immersion in hydrofluoric acid. The present invention provides catalysts which can convert gases containing NOx, CO, unburnt hydrocarbons, etc. from appratuses and engines using various organic fuels to harmless gases based on the reactions changing carbon compounds into carbon dioxide and water, and nitrogen oxides into nitrogen at temperatures close to room temperature, and the catalysts have high activity and easily produced and regenerated.
