abstract = {Tetragonal phase BaTiO3 was prepared by using hydrothermal calcination, with Ba(OH)2·8H2O and TiO2. g-C3N4 was prepared by using thermal condensation method with melamine as precursor. BaTiO3/g-C3N4 piezo-photocatalytic composites with different mass fractions were prepared by simple lapping. Structure, morphology and optical properties of the samples were characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-vis specoscopy. Properties of the composites were studied by simulating the effect of sunlight and ultrasonic wave on degradation of Rhodamine (RhB). It is found that 10% BaTiO3/g-C3N4 has the best visible light absorption performance, whereas the degradation rate of RhB is 97.81% within 100 min, which is 1.48 times that of g-C3N4. The trapping agent experiment showed that ·OH and ·O2− were the main active species under the conditions of piezo-photocatalysis.}
