[0031] Example 1
[0032] (1) 1 mole La 1.85 Na 0.15 Ce 2 O 7-δ (LNC) Preparation:
[0033] Prepare 0.01mol La 1.85 Na 0.15 Ce 2 O 7-δ :
[0034] Weigh 1.85 moles of La(NO 3 ) 3 ·NH 2 O: 1.85×324.92= 601.102 grams;
[0035] Weigh 0.15 mole of NaNO 3 :0.15×84.99=12.749g;
[0036] Weigh 2 moles of Ce(NO 3 ) 3 ·6H 2 O: 2×434.22=868.440 grams;
[0037] Weigh 6 moles of citric acid: 6×210.14=1260.840 grams;
[0038] (2) The NaNO 3、 Ce(NO 3 ) 3 ·6H 2 O, La(NO 3 ) 3 And citric acid were dissolved in deionized water;
[0039] (3) Pour all the above solutions into the citric acid solution, and add ammonia water to adjust the pH to 7;
[0040] (4) Put the mixed solution into a stirrer and heat to 70°C, stir continuously at 70°C, and add ammonia water during the stirring process to keep the pH of the solution at 7 until a gel is formed;
[0041] (5) Move the gel into the evaporating dish and heat it on the electric stove until self-propagating combustion occurs to form fluffy oxide powder;
