3D hierarchical FeO/Ag/BiMoO magnetic microspheres are fabricated through hydrothermal-photoreduction strategy, which fabricate an advanced photocatalytic-Fenton coupling system. The HO produced by photocatalysis could form the photo-Fenton system when combined with FeO under light illumination. The introduction of Ag nanoparticles could induce the localized surface plasmon resonance (LSPR), which provides "hot electrons" for promoting photocatalysis. The addition of FeO achieve the successful coupling of photocatalysis-Fenton, and enhanced the broad spectrum response of the final composite sample. The 3D hierarchical FeO/Ag/BiMoO exhibit excellent UV-Vis-NIR-driven photocatalytic performance for mineralization of high-toxic Aatrex and Bisphenol A. The addition of magnetic FeO is conducive to the magnetic separation, which favors practical application. The strategy provides thought-provoking insights for constructing new types of high-performance photocatalytic system.
