What is The effect of piezo-photocatalysis on enhancing the charge carrier separation in BaTiO3/KNbO3 heterostructure photocatalyst about?
## A C T In order to reduce the secondary recombination of photogenic charge carriers caused by the structural defects at the interface of traditional heterostructure photocatlysts, and the charge shielding effect of static condition on the built-in electric field in ferroelectric/piezoelectric photocatalyst, two typical piezoelectric photocatalysts, BaTiO 3 and KNbO 3 , were successfully compounded into a series of BaTiO 3 /KNbO 3 heterostructure photocatalysts for the first time. BaTiO 3 nanoparticles with good crystallinity are uniformly distributed on the surface of KNbO 3 prism to form the BaTiO 3 /KNbO 3 heterostructure. The piezo-response force microscopy (PFM) results and piezophotocatalytic degradation experiments stimulated by ultrasonic vibration and light irradiation show that the separation efficiency of photogenic charge carriers and degradation performance are enhanced by the synergistic effect of piezocatalysis and photocatalysis. The piezo-photocatalytic degradation efficiency of BaTiO 3 /KNbO 3 over direct lake blue 5B dye can reach up to 93.3%. The reaction rate constant of 0.3BaTiO 3 /0.7KNbO 3 over the target dye is 4.44 and 8.57 times higher than that of BaTiO
