One-dimensional visible-light-driven bifunctional photocatalysts based on Bi4Ti3O12 nanofiber frameworks and Bi2XO6 (XÂ =Â Mo, W) nanosheets

One-dimensional Bi4Ti3O12/Bi2XO6 (X = Mo, W) hierarchical heterostructures exhibit enhanced photocatalytic activity due to the photoinduced interfacial charge transfer based on the photosynergistic effect of the formed heterojunction.
