PURPOSE: To form a catalyst having a particle size of <=100Åby evaporating an iron-contg. compd. which is evaporated at <=500 deg.C and can form ferric oxide by reacting with an oxygen-contg. atmosphere, then oxidizing this component in an oxygen atmosphere. CONSTITUTION: The iron-contg. compd. which is evaporated at <=500 deg.C and can form the ferric oxide by reacting with the oxygen-contg. atmosphere is evaporated. This iron-contg. compd. is then oxidized the oxygen atmosphere. Consequently, the ferric oxide catalyst which has the particle size of the ferric oxide catalyst of <=100Åand can improve activity is obtd. The iron-contg. compd. includes carbonyl, chelate compd. ofβ-diketone, cyanide complex and ferrocene deriv. and includes, more specifically, iron (III) acetyl acetonate, ferrous ferroxycyanide, ferrocene or the like. |
