| 英文摘要 | Oxygen vacancies can provide active sites for catalysts, promoting catalytic activity. However, there are fewer nanozyme catalysts with oxygen vacancies. In this study, CeO2 metal -organic framework (CeO2-MOF) nanorods with oxygen vacancies are synthesized through a simple hydrothermal and calcination processes. The obtained CeO2-MOFs exhibit excellent nanozyme catalytic activity for antibacterial applications. The CeO2-MOF nanorods demonstrate intrinsic haloperoxidase-like activity by catalyzing the bromination of organic signaling compounds, outperforming the catalytic properties of pure CeO2. The activity of CeO2-MOF(6) is the best because of its large specific surface area of 103.638 m2/g, surpassing that of CeO2 at 74.752 m2/g. The oxygen vacancies are crucial in regulating the electronic structure of CeO2-MOFs, thereby improving the catalytic performance. The experiments of multiple substrates show that CeO2-MOF(6) exhibits good stability and recyclability. Additionally, CeO2-MOF(6) can catalyze the oxidation of Br with H2O2 to the corresponding hypobromous acid (HBrO), which exhibits strong antibacterial activity against typical marine bacteria (Pseudomonas aeruginosa). This study expands the range of biomimetic enzyme materials. It provides an efficient and green perspective and strategy for developing antibacterial and antifouling biomimetic catalysts, which offers a sustainable alternative for industrial applications in marine coatings and environmental protection. |
