This study presents a novel photocatalytic system for degradation of Eriochrome black-T (EBT) dye via green light-emitting diode (LED) light exposure. photocatalyst is comprised nanoscale components, i.e., poly(vinyl alcohol) (PVA), magnetic iron oxide nanoparticles (Fe3O4 NPs), gold NPs (Au and zinc nanorods (ZnO NRs), rendering an active high surface area. The most highlighted property from the structural facet superparamagnetic behavior Fe3O4 NPs, which provides facile collection reaction flask successfully recycled eight times without considerable reduction in catalytic behavior. Briefly, at its highest efficiency reached 51.4% (10 ppm solution, 5.0 mL) 64.75% (8 utilizing 10 mg designed (formulated as Fe3O4@PVA-Au/ZnO), under LED (7 W, 526 nm) exposure 60 min. Besides, mechanism EBT by as-prepared was proposed. Based on obtained results, presented method recommended scaling up large-scale exploitation purification water resources.
