The invention discloses a ternary complex nanometer system and a preparation method and application thereof. The system comprises an iron compound, a benzene-ring-containing micromolecule antineoplastic active compound and a polyphenol compound; a weight ratio of the iron compound to the benzene-ring-containing micromolecule antineoplastic active compound to the polyphenol compound is (1 to 4):(2to 10):(5 to 20). Relative to the prior art, according to the invention, different micromolecule compounds or medicines can be stably assembled only by a physical assembling means; the formed complexnanometer medicine not only has an antineoplastic treatment effect of the micromolecule antineoplastic active compound, but also has a ferroptosis treatment effect that the iron compound reacts with the polyphenol compound are mediated on the basis of an intracellular Fenton reaction; moreover, the novel complex nanometer medicine formed by the preparation method disclosed by the invention furtherhas an outstanding photothermal effect; chemotherapy, ferroptosis treatment and photothermal therapy can be integrated into one whole body, take a synergistic effect, beneficiate each other and achieve an all-in-one combined antineoplastic treatment effect.
