A nanocaged catalyst, a preparation method, and an application thereof. The formula of the catalyst is: NC-m[M(Salen1)X]-n[M'(Salen2)], where NC is a material having a nanocage structure, and M(Salen1)X and M'(Salen2) are each active centers; each M that occurs is independently selected from a Co ion, an Fe ion, a Ga ion, an Al ion, a Cr ion, and a mixture thereof; each M' that occurs is independently selected from a Cu ion, an Ni ion, and a mixture thereof; m is within a range of 0-100; n is within a range of 0-100; it is a condition that at least one of m and n is not equal to 0; each Salen1 and Salen2 that occurs is independently a Schiff base derivative; and X is an axial anion selected from substituted or unsubstituted acetate, substituted or unsubstituted benzenesulfonate, substituted or unsubstituted benzoate, F-, Cl-, Br-，I-，SbF6 -，PF6 -，BF4 -, and a mixture thereof. |
