Claim 6:
7. A preparation method for the cerium-zirconium solid solution according to claim 1, comprising the following steps:
1) mixing: preparing an initial mixture of an aqueous solution containing trivalent cerium ions and zirconium ions;
2) oxidation reaction: adding hydrogen peroxide to the acidic initial mixture according to a required amount of trivalent cerium ions and tetravalent cerium ions, and adding a precipitant to adjust pH of the solution to 10-11 to obtain a precursor solution;
3) a first hydrothermal reaction: after the first hydrothermal reaction, calcining the precursor solution in an inert gas to obtain the cerium-zirconium solid solution.
