Ferroelectric polarization-enhanced photodegradation performance for dyes in BaTiO3/AgAlO2 heterostructure
Source abstract
Abstract
Introducing an internal electric field into photocatalysts is an efficient strategy to inhibiting the charge carrier recombination which is the obstacle to the photocatalytic technology. Herein, we propose to construct BaTiO 3/AgAlO 2 heterostructure with improved photocatalytic performance through a polarization effect. The ferroelectric BaTiO 3 particles with nanocube morphology are distributed over ellipsoid-like AgAlO 2 . The UV–vis absorption edges extend from 415 to 545 nm owing to the energy band overlap. The ultrasound-assisted photocatalysis efficiency of methyl blue under BaTiO 3/AgAlO 2 is increased by 22 %. Photoelectrochemical results indicate that the separation efficiency of photoinduced carriers is enhanced by the polarization effect. Moreover, the photocurrent of the BaTiO 3/AgAlO 2 after polarization is increased by 1.6 times of that before polarization. Piezoelectric force microscope shows that the phase angle has a great change, confirming the polarization switching process. The butterfly-shaped displacement-voltage hysteresis loop confirms the local piezoelectric response originated from BaTiO 3.
