Engineering polydopamine-functionalized NH2-MIL-125 (Ti) for tetracycline degradation and antibacterial applications
Methods for the precise construction of NH2-MIL-125 (Ti) with chemical bonding are indispensable for the synthesis of MOF-based photocatalytic materials, which possess high activity, stability and biocompatibility. Herein, polydopamine (PDA)-functionalized NH2-MIL-125 (Ti) was prepared using cross-linking reaction between catechol groups in PDA and amine groups in NH2-MIL-125 (Ti), instead of the self-polymerization process. The conjugation of functional groups had strong chemical bonding interactions. Benefiting from the assembly of PDA, the optimum photocatalyst presented superior tetracycline (TC) degradation efficiency, as well as 99.9 % and 99.4 % antimicrobial rates against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), respectively. The possible photocatalytic mechanisms of TC degradation and antibacterial activity were proposed and verified by EPR results. This work provides in-depth scientific insights for photocatalysis and biomedical field.
期刊介绍：
ACS Applied Materials & Interfaces is a leading interdisciplinary journal that brings together chemists, engineers, physicists, and biologists to explore the development and utilization of newly-discovered materials and interfacial processes for specific applications. Our journal has experienced remarkable growth since its establishment in 2009, both in terms of the number of articles published and the impact of the research showcased. We are proud to foster a truly global community, with the majority of published articles originating from outside the United States, reflecting the rapid growth of applied research worldwide.
