| 摘要 |
Herein, Co- and Fe-based single-atom nanozymes (M/N-PC, M = Co or Fe) were successfully fabricated and their catalytic performances for patulin degradation were evaluated systematically. Co/N-PC, consisting of Co-N-4 and nanoclusters sites, achieved a higher patulin degradation efficiency (99.4 %, within 60 min) than Fe/N-PC (only consisting of Fe-N-5 sites). Synergistic interactions between Co-N-4 and Co nanoclusters greatly enhanced electron density near the Fermi level in Co/N-PC, enabling its high catalytic performance. The degradation products of patulin exhibited negligible cytotoxicity. The M/N-PCs demonstrated good reusability, broad pH adaptability and high practical application potential for patulin degradation in apple juice. M/N-PC also exhibited high efficiency in degrading aflatoxin B1, deoxynivalenol and zearalenone (similar to 100 %, 10-40 min). This study provides indepth insights into the relationship between metal active site structures in M/N-PCs and their catalytic properties for mycotoxin detoxification, offering guidance for the design of highly efficient single-atom nanozymes. |
