Enhancement of charge separation in ferroelectric heterogeneous photocatalyst Bi ₄ (SiO ₄ ) ₃ /Bi ₂ SiO ₅ nanostructures

nanosheets and the band bending at the 0D-2D interface of the heterostructures have been proved to accelerate the photoinduced charge separation and the movement of separated carriers to the interface, which further improves the photodegradation performance. This work provides a novel strategy for adjusting the photoinduced carrier transfer route in the ferroelectric materials and designing novel photocatalysts with ultrafast charge separation and large active surface area.
