Abstract
The invention discloses a method for preparing a lanthanum-cerium-zirconium complex through atomization combustion, which comprises the following steps of: adding lanthanum nitrate, strontium nitrate and zirconium nitrate into ethanol water; after dissolution, controlling the temperature to 35-45 DEG C; and then atomizing and combusting in a combustion chamber at 450-600 DEG C to obtain a lanthanum-cerium-zirconium complex. Furthermore, the mass concentration of the ethanol water is 40-75%, and the weight parts of the lanthanum nitrate, strontium nitrate and zirconium nitrate are 5-15 parts, 20-80 parts and 15-60 parts respectively. Compared with the prior art, the method disclosed by the invention has the advantages of simple technology, easiness in operation, good complex activity and strong high temperature resistance and poison tolerance.
