Abstract

A self-templated approach has been developed for the preparation of FeMnO3 nanoparticles filled in the hollow core of polypyrrole (PPy) nanotubes by an in situ polymerization process accompanied by the etching of FeMnO3 nanofibers. The prepared FeMnO3@PPy nanotubes exhibited a superior peroxidase-like activity. The catalytic reaction system has been used for the sensitive colorimetric detection of glutathione with a low detection limit and good selectivity.

摘要

一种自模板方法已被开发用于通过原位聚合过程制备填充在聚吡咯（PPy）纳米管中空核中的 FeMnO3 纳米粒子，同时伴随着 FeMnO3 纳米纤维的蚀刻。所制备的 FeMnO3@PPy 纳米管表现出优异的过氧化物酶样活性。该催化反应体系已用于谷胱甘肽的灵敏比色检测，具有低检测限和良好的选择性。
