NOVELTY - A high temperature resistant catalyst comprises a core-shell structure based on (mass %) yttrium-stabilized zirconium nanoparticles (70-90) coated by perovskite (10-30).    USE - A high temperature resistant catalyst used for catalytic combustion reaction of methane (claimed).    ADVANTAGE - The catalyst is inexpensive, has improved thermal stability, can be easily prepared, is environment-friendly, and requires low combustion starting and complete temperature of methane.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the high temperature resistant catalyst, comprising:    (A) preparing 0.5-4 mol/L mixed aqueous solution comprising yttrium nitrate hexahydrate and zirconium oxychloride according to amorphous solid yttrium-stabilized zirconium material YxZr1-xO2-delt a (I) ;    (B) preparing 5-25 mass % precipitator with a molar number of sigma niXi, and diluting with deionized water;    (C) adding the mixed aqueous solution and the precipitator solution in a reactor at constant speed, agitating for 5-12 hours at high speed, and filtering, where pH of filtrate is 9-11; and rinsing filter cakes and then drying at 120 degrees C, and calcining for 3 hours at 400 degrees C to obtain (I) ;    (D) adding the solid material in water at 6-10 g/100 mL water, using a high-speed dispersion machine to prepare a uniform and stable slurry, where agitating is carried out for 5-10 minutes at 6000-11000 revolutions/minute (rpm); continuing to agitate for 0.5-2 hours to obtain yttrium-stabilized zirconium slurry;    (E) preparing 0.1-1 mol/L mixed aqueous solution of La1-x'Srx'Mn1-yNiyO3 (II);    (F) preparing 5-25 mass % precipitator with a molar number of sigma niXi, and diluting with deionized water;    (G) adding the mixed solution of (II) to the yttrium-stabilized zirconium slurry, making the content of perovskite be 10-30 mass % and the yttrium-stabilized zirconium be 70-90 mass %;    (H) agitating for 5-12 hours at high speed, and filtering, where pH of the filtrate is 11-13; and rinsing the filter cakes until the filtrate is neutral; and    (I) drying the filter cakes at 100-120 degrees C, and calcining for 3-6 hours at 900-1100 degrees C.    x=0.06-0.12;    delta=0.010.03;    ni=molar number of metal ions;    Xi=valence of metal ions;    x'=0-0.3; and    y=0-1.
