In this work, we report a zeolitic imidazolate framework (ZIF-67) which could catalyze 3,3',5,5'-tetramethylbenzidine (TMB) to produce a yellow chromogenic reaction. ZIF-67 showed high peroxidase-like activity compared with copper-based metal-organic framework nanoparticles (Cu-MOF), zinc-based metal-organic framework nanoparticles (ZIF-8), and horseradish peroxidase (HPR). We discovered for the first time that the cobalt-based metal-organic framework nanoparticles possess intrinsic peroxidase-like activity without HO, which can be employed to quantitatively monitor the HO Graphical abstract ᅟ.
在这项工作中，我们报告了一种沸石咪唑酯骨架（ZIF-67），它可以催化 3,3',5,5'-四甲基联苯胺（TMB）产生黄色显色反应。与铜基金属有机骨架纳米粒子（Cu-MOF）、锌基金属有机骨架纳米粒子（ZIF-8）和辣根过氧化物酶（HPR）相比，ZIF-67 表现出更高的过氧化物酶样活性。我们首次发现钴基金属有机框架纳米粒子具有内在的过氧化物酶样活性，无需 HO，可用于定量监测 HO 图摘要 ᅟ。
