Background: The increasing uranium containing wastes generated during uranium mining and finishing pose a huge threat to the environment and human health, and thus robust strategies for on-site monitoring of uranium pollutant are of great significance for environmental protection around uranium tailings.
Results: Herein, a facile "turn-on" colorimetric platform that can achieve uranium detection by spectrometry and naked eyes was developed based on the uranium-enhanced nanozyme activity of covalent organic framework (JUC-505). Thanks to the extended π-conjugated skeleton and donor-acceptor (D-A) structure, JUC-505 exhibited superior photo-activated nanozyme activity, which would be prohibited when the cyano group in JUC-505 skeleton was transformed to the amidoxime group.
Article Synopsis
- The study focuses on developing covalent organic frameworks (COFs) to create nanozymes for use in catalysis and sensing applications.
- Through a chemical reaction, a new two-dimensional COF called DAFB-DCTP was created, which possesses both hydrolytic and photosensitive properties due to the inclusion of pyridine groups.
- This COF acts as an artificial enzyme capable of catalyzing specific reactions, enabling the detection of harmful compounds and offering a user-friendly, smartphone-compatible method for colorimetric analysis, demonstrating promising applications in environmental monitoring and safety.
