Summary: Piezoelectric devices made of ZnO nanowires have attracted great interest as potential nanogenerators and sensors in the past decade. However, their characteristics are limited by the screening effect of the piezoelectric potential generated under mechanical solicitations. To address this issue, we developed the compensatory Sb doping of ZnO nanowires and achieved significant incorporation of Sb dopants.

Summary: The separation of photogenerated carriers is crucial for improving the efficiency of photocatalysis. This study proposes pine needle-like BaTiO3/ZnO continuous nanofibers with numerous interfaces, which have both photocatalytic and piezoelectric properties. Under ultrasonic waves, the piezoelectric potential generated by BaTiO3 and ZnO alternately breaks the shielding and efficiently separates photogenerated carriers, leading to an increased reaction rate constant compared to photocatalysis alone. This work provides a practical application significance in the field of water treatment.
