摘要

•Ag2O/Bi4Ti3O12 nanoflowers with Ag2O nanoparticles uniformly decorated on surface BiTO nanosheets have been synthesized.•Spontaneous polarization can promote the separation of carriers, enhancing photocatalytic performance of Ag2O/Bi4Ti3O12.•The photocatalytic efficiency of Ag2O/Bi4Ti3O12 was further improved by introducing ultrasonic vibration and pre-poling.
