Two iron(III)-based metal-organic frameworks (MOFs) are found to behave as efficient peroxidase mimics and catalyze the oxidation of different peroxidase substrates by H2O2 accompanied with significant color change in the solution. With these findings, a simple and sensitive colorimetric assay to detect H2O2 and ascorbic acid has been established.
