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:
The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results.
Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
