Abstract

This article presents a new enzyme-mimic activity of non-noble metal-based bimetallic Fe-Co NPs. This type of enzyme-mimic exhibits much higher affinity to H2O2 over other NPs-based peroxidase mimetics by at least one order of magnitude due to the synergistic effects between the two metals.

摘要

本文提出了一种新的非贵金属基双金属 Fe-Co NPs 的酶模拟活性。由于两种金属之间的协同作用，这种类型的酶模拟物对 H2O2 的亲和力比其他基于 NPs 的过氧化物模拟物至少高出一个数量级。
