摘要	Piezo catalysis has recently been considered an important technology in environmental treatment. In this study, a type II heterojunction of K2Ti6O13/TiO2 composite is successfully prepared by a hydrothermal method for the highly efficient piezo catalytic degradation of tetracycline. The factors influencing the piezo catalysis of tetracycline are systematically studied and discussed, including pH value, competition of anions/cations, ultrasonic power, ultrasonic frequency, and temperature, etc. Free radical sacrificial agents (EDTA-2Na, DMSO, AgNO3, and P-BQ, etc.) are utilized to better understand the degradation mechanism by piezo catalysis, and holes are found to play a dominant role in the catalytic process, and center dot O-2(-) comes the second. The combination of K2Ti6O13 and TiO2 constructs a type II heterojunction of the highly efficient separation of piezo electrons and holes, thus systematically increasing the piezo catalytic performance. This work provides a new idea to degrade organic pollution through piezo catalysis and the potential application of piezo catalysis in environmental treatment. (C) 2021 Elsevier B.V.
