TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: The method further comprises: dissolving a copper precursor in a solvent to prepare the copper-containing solution; adding a zirconium precursor to the copper-containing solution; adding a carrier to the copper-containing solution; calcinating the metal oxide; adding a metal oxide to a solution comprising a platinum-based metal precursor and heating the metal oxide-containing solution; and calcinating the oxidizing catalyst. The precursor-containing solution is heated at 100-200degrees C for 1-3 hours. The metal oxide is calcinated at 450-550degrees C for 1-3 hours. The solution comprising the platinum-based metal precursor is prepared by dissolving the platinum-based metal precursor in a solvent consisting of water, N,N-dimethylformamide and/or methanol. The metal oxide-containing solution is heated at 100-200degrees C for 15-45 minutes. The oxidizing catalyst is calcinated at 650-750degrees C for 0.5-2 hours. Preferred Composition: The metal oxide further comprises zirconium oxide. The fuel oxidizing catalyst further comprises a platinum-based metal. Preferred Components: The transition metal is nickel, cobalt and/or iron (preferred). The fuel oxidizing catalyst comprises 10-30, preferably 5-20 wt.parts of cerium oxide, 0.1-5, preferably 0.1-2 wt.parts of transition metal oxide, 1-10 wt.parts of copper(I) oxide, 5-20 wt.parts of zirconium oxide and 0.1-50 wt.parts the platinum-based metal. The cerium precursor is cerium nitrate, ammonium cerium nitrate, cerium acetate, cerium chloride and their hydrates. The transition metal precursor is transition metal nitrate, transition metal acetate, transition metal chloride and/or their hydrates. The metal oxide is supported on a carrier. The carrier is aluminum oxide, titanium oxide, silicon oxide and/or cordierite. The platinum-based metal is platinum, palladium, ruthenium and/or rhodium. The copper precursor is copper nitrate, copper acetate and their hydrates. The solvent for dissolving the copper precursor is water, methanol and/or ethanol. The zirconium precursor is zirconium nitrate, ammonium zirconium nitrate, zirconium acetate, zirconium chloride and their hydrates. The platinum-based metal precursor is chloroplatinic acid, platinum(II) 2,4-pentanedionate, dichlorodiamineplatinum(II), platinum(II) chloride, platinum(II) bromide, palladium(II) chloride, palladium(II) acetate, palladium(II) 2,4-pentanedionate, ruthenium chloride, ruthenium(III) 2,4-pentanedionate, ammonium hexachlororuthenate(IV), dirhodium tetra-acetate, rhodium(III) nitrate hydrate and their hydrates. EXAMPLE - Copper nitrate trihydrate (0.307 g) was dissolved in water (6 ml) to prepare a copper aqueous solution. Then cerium(III) nitrate hexahydrate (5.050 g) and iron(III) nitrate hexahydrate (2.062 g) were dissolved in the copper aqueous solution to prepare a mixed solution. Then, aluminum oxide (7.5 g) was added to the mixed solution. The aluminum oxide had an average particle diameter of 3 mm. The mixed solution including aluminum oxide was stirred for 30 minutes to impregnate the solution into the aluminum oxide. The impregnated aluminum oxide was heated to 120degrees C for 2 hours to prepare a fuel oxidizing catalyst. The prepared fuel oxidizing catalyst was calcinated at 500degrees C for 1 hour. The prepared fuel oxidizing catalyst included cerium dioxide (20 wt.parts), iron oxide (4 wt.parts), cupric oxide (1 wt.part) and aluminum oxide (75 wt.parts).
