摘要

Perovskite-type alkaline niobate nanofibers were prepared by electrospinning. KNbO₃ nanofibers with lower BET exhibit higher photocatalytic efficiency than NaNbO₃ with similar phase structure and morphology. The internal electric field, which does not exist in antiferroelectric NaNbO₃, induced by spontaneous polarization in ferroelectric KNbO₃ can promote the separation and accelerate the movement of photogenerated charge carriers.
