| 摘要: |
| 单原子催化剂（SACs）具有高原子利用效率以及高催化活性，在各种催化体系中均表现出优异的性能.其原子级别的活性位点与天然的金属蛋白酶类似，因此单原子纳米酶（SAzymes）的概念也应运而生.而金属有机框架（MOF）由于其具有高孔隙率的特点，可以作为合成SAzymes的前驱体.该文总结了使用MOF前体/模板构建SACs的合成策略，以及SAzymes的生物应用，提出了基于MOF衍生的SAzymes的发展挑战和前景. |

| Abstract: |
| Due to the high utilization efficiency of atom and catalytic activity, single atom catalysts (SACs) show excellent performance in various catalytic systems. Their atomic level active sites are similar to natural metalloproteinases, so the concept of single atom nanozymes(SAzymes) came into being. With its high porosity, metal-organic-framework (MOF) can be used as a precursor for the synthesis of SAzymes. In this review, the synthesis strategies of SACs constructed by MOF precursor/template and their biological applications are summarized. Finally, the challenges and prospects for the development of monatomic nanozymes based on MOF derivatives are proposed. |
