In this study, magnetically separable, highly efficient full-spectrum light active WO_2.72/Fe₃O₄ nanocomposites were synthesized by a solvothermal method and well characterized. The photocatalytic property of WO_2.72/Fe₃O₄ nanocomposite toward photodegradation of methylene blue (MB), methyl orange (MO), and rhodamine B (Rh B) dyes under solar and photoreduction of Cr(VI) under ultraviolet (UV), visible, and solar light were studied. The WO_2.72/Fe₃O₄ nanocomposite exhibited excellent photocatalytic activity for the photodegradation of MO, MB, and Rh B dyes under solar light and photoreduction of Cr(VI) under visible, UV, and solar light. The WO-FO-0.5 nanocomposite exhibited 2.9, 1.6, and 2.0 times the photocatalytic activity of Fe₃O₄ for Cr(VI) photoreduction under solar, visible, and UV and 20, 29.2, and 16 times that of Fe₃O_4, for Rh B, MB, and MO under solar light. It doesn't show only universal applicability for photocatalysis of different organic and inorganic pollutants but, also outstanding stability and easy separability. The nanocomposite also exhibited higher photocatalytic activity than that reported for photoreduction Cr(VI) under solar light. It is also convenient for large-scale applications due to its low cost, eco-friendliness, and easy preparation. Therefore, it is a promising candidate for environmental remediation under full-spectrum solar light.
