摘要	Porous bimetallic TiO2–Fe2O3 composite nanofibers with different Fe2O3 compositions (0–40 wt%) were prepared via a simple one-pot electrospinning approach. The surface areas, pore diameters, crystallinity and mesostructures of the bimetallic nanofibers were reasonably tuned by changing the Fe2O3 compositions. A feasible mechanism of TiO2 nanofiber modified with Fe2O3 was proposed. The sensing results showed that TiO2–Fe2O3 nanofibers with an appropriate Ti/Fe ratio exhibited much better Fenton activity than pure TiO2 nanofibers. The best Fenton properties of methylene blue (MB) degradation were found for 60 wt% TiO2-40 wt% Fe2O3 nanofibers, which formed a progressive TiO2/Fe3Ti3O10/Fe2O3 triple-heterojunction and accelerated charge transfer and Fe3+/Fe2+ cycle reaction efficiency. More active sites were responsible for the high activity in the Fenton reaction. © 2022 Elsevier Ltd and Techna Group S.r.l.
