Structure-Activity Mechanism of Iron Oxide Nanozymes

The discovery of highly stable and low-cost nanozymes, nanomaterials with enzyme-like activity, opens a new portal for breaking through the application limitations of delicate natural enzymes. Iron oxide nanozymes, as one of the most representative nanozymes, were first discovered to exhibit enzyme-like activity, and were systematically and in-depth studied. Researches have found some structural factors that have an important impact on the catalytic activity. In this chapter, we introduce the enzyme-like activities of iron oxide nanozymes and systematically review the elucidated structure-activity relationships to gain insight into their enzyme-like catalytic mechanisms.
