Abstract

Herein, we report a heterogeneous single iron atom catalyst exhibiting excellent peroxidase, oxidase and catalase enzyme-like activities (defined as single atom enzymes, SAEs), exceeding those of Fe3O4 nanozymes by a factor of 40. Our findings open up a new family of artificial materials that mimic natural enzymes.

摘要

在此,我们报道了一种具有优异过氧化物酶、氧化酶和过氧化氢酶样活性(定义为单原子酶,SAEs)的多相单铁原子催化剂,其活性超过四氧化三铁纳米酶的 40 倍。我们的发现为模拟天然酶的人工材料开辟了一个新的家族。
