Starting with metal–organic frameworks (MOFs), a facile process was demonstrated toward the synthesis of porous FeP nanocubes. Herein, Prussian blue nanocubes were used as iron-based MOFs precursors, and converted into FeP nanocubes through the thermal phosphidation reaction. Then, the FeP nanocubes were exploited as a peroxidase mimetic, which not only has the advantages of low cost, high stability, and easy preparation, but also follows Michaelis–Menten behaviors and shows strong affinity to substrates. On the basis of high catalytic activity of FeP nanocubes, a rapid, and convenient approach was developed for the colorimetric detection of H2O2 from 2 μM to 130 μM and with a detection limit of 0.62 μM. The good catalytic activity and high stability make the porous FeP nanocubes a useful catalyst for a wide range of potential applications in catalysis and biotechnology.
