The catalyst increases mechanical strength & widens the range of available temp. and is inclined to supersede platinum catalyst maintaining continuance of catalyst function. Its catalytic composition for oxidation is Fe2O3-MA12O4-Bi2O3-Ce2O3. MA12O4, spinel structure, is used for a carrier and worked as a catalyst also. M in MA12O4 shows Mg, Ma, Ca, Br, Ba etc. Fe2O3 is used for for a main catalyst and Ce2O3 is worked as a stabilizer to maintain continuance of catalyst function. The carrier contains Fe2O3 10-40wt %, Bi2O3 3.5-6wt % Ce2O3 0.5-2wt%.
