Fabrication of visible-light-responsive TiO2/α-Fe2O3-heterostructured composite for rapid photo-oxidation of organic pollutants in water
In this present work, a visible-light-responsive TiO 2 /α-Fe 2 O 3 -heterostructured nanocomposite was fabricated by hydrothermal and ultrasonication methods. To unravel the physicochemical and optical characteristics, the as-fabricated photocatalysts were characterized by PXRD, FT-IR, HRSEM, HRTEM,...

-heterostructured nanocomposite was fabricated by hydrothermal and ultrasonication methods. To unravel the physicochemical and optical characteristics, the as-fabricated photocatalysts were characterized by PXRD, FT-IR, HRSEM, HRTEM, UV–Vis DRS absorption, and PL analysis, respectively. The optical band gap (

composite photocatalyst was evaluated towards the degradation of aqueous methylene blue (MB) dye under visible-light irradiation. The results showed that the heterostructured α-Fe

(47.3%) within 100 min. The enriched photocatalytic efficiency is due to the enhanced visible-light response following by interfacial charges transfer between TiO

which in turn allows the formation of a high yield of separated electron–hole (e
