摘要： Establishing an effective and sustainable strategy for zearalenone (ZEN) degradation is of great significance to agricultural development and food safety. Herein, more than 98 % of ZEN (2 ppm) was photocatalytic degraded within 90 min over the oxygen-deficient Bi2WO6 ultrathin layers (BWO-U), along with the sharp elimination of biotoxicity to GES-1 cells. Theoretical calculations and characterizations revealed the ultrathin structure and oxygen vacancies endowed BWO-U with strengthened photoelectrochemical activity and O2-adsorption capacity, facilitating the generation of center dot O2- and 1O2 which play decisive roles in ZEN degradation. Furthermore, a possible mechanism was proposed based on nine intermediates identified via LC-MS, including the steps of cis-trans isomerization, oxidation and cleavage. Eventually, the method also exhibited immense potential in reducing ZEN-contamination in corn oil, and made no significant impact on the quality of corn oil. This work might provide a feasible strategy to mitigate ZEN-contamination and cast a new light on the ROS-mediated mechanism.
