Facile synthesis of covalent organic framework derived composite Fe-COF as a peroxidase-mimicking artificial enzyme

An artificial catalyst (Fe-COFs) with peroxidase-like activity was successfully synthesized at room temperature and applied to catalyze the reaction between TMB and H2O2. This catalytic system can be used not only to detect residual hydrogen peroxide (H2O2) in milk efficiently, but also to degrade rhodamine B (RhB) in waste water.
