Abstract

Efficient charge separation is quite significant to obtain high photocatalytic performance. In this work, piezoelectric-based composite photocatalyst film PDMS-PMN-PT@TiO ₂ possessing high recoverability was prepared. The spatial electric field of PMN-PT was introduced into photocatalyst system by ultrasonic wave vibration to accelerate charge separation. Compared with magnetic stirring, ultrasonic wave vibration greatly improved the photocatalytic degradation efficiency of rhodamine B (RhB) over PDMS-PMN-PT@TiO ₂ film by about 55%. A possible improvement mechanism that spatial electric field promotes charge separation was presented herein. The piezoelectric potential output demonstrated the piezoelectricity of composite film. The durability experiments of PDMS-PMN-PT@TiO ₂ film indicated its great stability over several runs.
