Yolk-shell nanocomposite particles (YSNPs) have been extensively investigated because of their great application potential and unique properties attributed to their distinct structures and multiple discrete functions. In this study, Fe 3 O 4 @Void@PMAA@Void@TiO 2 , a special YSNP with double shells and dual cavities (denoted as DDYSNPs), was prepared by conducting dispersion polymerization with a high production rate and by using a hydrothermal strategy. The synthesized DDYSNPs, which effectively integrate inorganic and organic functions, exhibit an outstanding photocatalytic activity under ultraviolet light irradiation for five experimental cycles and show an excellent adsorptive property for heavy metal ions. These comprehensive properties are mainly attributed to the novel structure of double-shelled and dual-cavity structures. Graphical Abstract ᅟ
