Synthesis of 3D SbO-based heterojunction reinforced by SPR effect and photo-Fenton mechanism for upgraded oxidation of metronidazole in water environments.

The traditional homogenous and heterogenous Fenton reactions have frequently been restrained by the lower production of Fe ions, which significantly obstructs the generation of hydroxyl radicals from the decomposition of HO. Thus, we introduce novel photo-Fenton-assisted plasmonic heterojunctions by immobilizing FeO and Bi nanoparticles onto 3D SbO via co-precipitation and solvothermal approaches. The ternary SbO/FeO/Bi composites offered boosted photo-Fenton behavior with a metronidazole (MNZ) oxidation efficiency of 92% within 60 min.
