摘      要：In this study,a hierarchical Bi2O3/TiO2 fibrous composite was in-situ fabricated on an electrospun TiO2 nanofiber at ambient *** the Bi2O3/TiO2 composite,S-scheme electron migration occurred between Bi2O3 and *** the photocatalytic degradation of phenol under simulated sunlight,the asprepared Bi2O3/TiO2 nanofibers considerably outperformed Bi2O3 nanoparticles and TiO2 *** improvement is contributed by maintaining and effectively utilizing the useful carriers and consuming the useless holes and electrons,realized by the S-scheme heterojunction and hierarchical *** study also provides an alternative design fashion for photocatalysts.
