A novel dual-emission luminescent Eu-MOF/g-C₃N₄ nanocomposite is developed as a bifunctional platform for aflatoxin B₁ (AFB₁) detection and degradation. This material achieves highly sensitive ratiometric fluorescence detection with a limit of detection of 11.48 ppb, while simultaneously delivering 94.33% photocatalytic degradation efficiency under visible light within 120 min. The integrated system demonstrates exceptional anti-interference performance in complex food matrices, with spiked recoveries of 97.4%-101.22% in peanut oil samples and sustained catalytic activity over multiple cycles. By combining rapid visual detection with efficient detoxification in a single material, this platform addresses the critical need for comprehensive mycotoxin control strategies and provides a versatile paradigm for the development of multifunctional nanomaterials for food safety and environmental applications.
