Enhancement of the Piezocatalytic Response of La-Doped BiFeO₃ Nanoparticles by Defects Synergy.

ABSTRACT: Because of their intrinsic polarization and related properties, ferroelectrics attract significant attention to address energy transformation and environmental protection. Here, by using trivalent-ion-lanthanum doping of BiFeO₃ nanoparticles (NPs), it is shown that defects and piezoelectric potential are synergized to achieve a high piezocatalytic effect for decomposing the model Rhodamine B (RhB) pollutant, reaching a record-high piezocatalytic rate of 21 360 L mol^-1 min^-1 (i.e., 100% RhB degradation within 20 min) that exceeds most state-of-the art ferroelectrics. The piezocatalytic Bi_0.99La_0.01FeO₃ NPs are also demonstrated to be versatile toward various pharmaceutical pollutants with over 90% removal efficiency, making t
