Return to Japanese Patent Table of Contents JP59109244 Abstract PURPOSE: To obtain a catalyst having high activity by incorporating alloys of composite oxides, composite carbides or the like consisting of Fe, Ni, Co, Pt, Pd, Ru, Rh, Os, Ir, Th, Sc, Y, La, Se, Pr, Nd or the like. CONSTITUTION: Alloys incorporating one kind of transition elements which belong to the VIII group such as Fe, Co, Ni, Ru; one kind of elements which belong to the IIIA such as Sc, Y, La, Ce; the IVA group elements such as Ti, Zr, Hf; the VA group elements such as V, Nb, Ta; the IIIB group elements such as Al, Ga; one kind of Si, Ge are allowed to react catalytically with a reactive gas (one kind of gas among O2, CO, NO, NO2, N2O) at 100oC temp. Thus, the reaction gas is dissociated into C, O, N which are combined with the elements of III, IV, V groups to be plural systematic composite oxides, composite carbides, and composite nitrides. |
