TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The perovskite catalyst composition is represented by the formulae (I) - (III) (preferably (IV) - (VI):(AzA'(1 - z))(B(1 - x - y)NixRhy)O(3 - gamma) (I)(LazA'(1 - z))(Fe(1 - x - y)NixRhy)O(3 - gamma) (II)(LazCe(1 - z))(B(1 - x - y)NixRhy)O(3 - gamma) (III)LaFe0.7Ni0.25Rh0.05O(3 - gamma) (IV)La0.8Ce0.2Fe0.7Ni0.25Rh0.05O(3 - gamma) (V)La0.8Ce0.2Fe0.7Ni0.3O(3 - gamma) (VI)A, A' = lanthanide or actinide families, or group IIa of Mendeleev's periodical table of elements (preferably La, Ce, Ca, or Sr);B = transition metal groups of columns IIIb, IVb, Vb, VIb, Ib, IIb, or group VIIIb of the Mendeleev's periodical table of elements (preferably Mn, Fe, Co, or Al);x = 0-0.7, preferably 0-0.5;y = 0-0.5, preferably 0-0.25;z = 0-1, preferably 1;andgamma = sub stoichiometric value of oxygen to obtain the electric neutrality of the perovskite compound.It is provided that x + y = 0-0.8.Preferred Condition: The operating catalyst conditions are 500-1300, preferably between 600-1100 degrees C and 1 x 105-3 x 106, preferably between 105-106 Pa.The operating catalyst conditions are any oxidant feed, preferably pure oxygen, oxygen and inert gas mixture, steam, and/or carbon dioxide. EXAMPLE - A lanthanum nitrate (La(NO3)3) (5.3 g), ferric nitrate (Fe(NO3)3) (4.6 g), nickel nitrate (Ni(NO3)2) (1.2 g), and 10 w/w% rhodium nitrate solution (0.83 g) were dissolved in distilled water (300 ml) and slowly dropped in a solution having citric acid (7.7 g) dissolved in ethylene glycol (400 ml). After mixing, the resulting solution was heated at 90 degrees C for 4 hours. The evaporation of water from the solution brought to the formation of a sol. The catalyst was dried in oven at 90 degrees C. The oven temperature was increased to 180 degrees C overnight. The formed gel was dried. The obtained solid was calcined at 500 degrees C for 4 hours and then 900 degrees C for 12 hours. The X-ray diffraction (XRD) shows the perovskite cubic pattern and the surface area after calcination was 8 m2/g.
