Highly efficient and reusable Sr4Al14O25: Eu2+, Dy3+@ZnO nanocomposites were developed for the photocatalysis of toxic pollutants from aqueous systems. The materials exhibited excellent photophysical and photocatalytic properties, degrading pollutants rapidly under UV-Visible irradiation.
Highly efficient and reusable Sr4Al14O25: Eu2+, Dy3+@ZnO nanocomposites were developed for the photocatalysis of toxic pollutants from aqueous systems. The structural, photophysical and photocatalytic properties of the materials were investigated by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray, and photoluminescence spectroscopy. The synergistic effects between persistent luminescent Sr4Al14O25: Eu2+, Dy3+ phosphor and ZnO significantly enhanced the photocatalytic efficiencies of the composites where the phosphor performed as nano-illumination sources to activate ZnO in situ. The composite system degraded aqueous methyl orange in less than 1 h under UV-Visible irradiation. The materials developed are environment friendly, cost effective, highly efficient and reusable making them powerful candidates for industrial waste water remediation. (C) 2020 Elsevier B.V.
