摘要： Toxic phenol pollutants pose a great threat to the environment, it is urgent to develop an efficient and recyclable method to monitor phenol. Herein, we reported the synthesis of catalase-Fe3O4@ZIF-8 (CAT-Fe3O4@ZIF-8) through a novel amino-acid-boosted one-pot embedding strategy that synergically integrated catalase and magnetic Fe3O4 nanoparticles with ZIF-8. As expected, CAT-Fe3O4@ZIF-8 exhibited enhanced catalytic activity compared with Fe3O4@ZIF-8, CAT@ZIF-8 and catalase. Depending on the satisfactory performance of CATFe3O4@ZIF-8, a colorimetric detection platform for phenol based on CAT-Fe3O4@ZIF-8 was constructed. The corresponding detection limit was as low as 0.7 mu M, and a wide linear range of 5-100 mu M was obtained. Besides, CAT-Fe3O4@ZIF-8-based colorimetric detection platform has been verified to possess high stability and recyclability. The proposed method was proven to have potential practical applications in the field of water treatment, which would advance efficient, recyclable monitoring of water quality.
