High-performance photocatalytic reduction of Cr(VI) using a retrievable Fe-doped WO₃/SiO₂ heterostructure.

ABSTRACT: The enhancement of the photocatalytic performance of pristine WO₃ was systematically adjusted due to its fast recombination rate and low reduction potential. A designed heterostructure photocatalyst was necessarily synthesised by Fe³⁺ metal ions doping into WO₃ structure with and composition modification. In this study, we synthesised a retrievable Fe-doped WO₃/SiO₂ heterostructure using a surfactant-assisted hydrothermal method. This heterostructure was then employed as an effective photocatalyst for the removal of Cr(VI) under visible light irradiation. Enlarged photocatalytic reduction was observed over a synergetic 7.5 mol% Fe-doped WO₃/SiO₂-20 nanocomposite, resulting in dramatically increased activity compar
