A new promising mimetic enzyme, a [2Fe-2S] cluster-porphyrin hybrid complex ([2Fe-2S]2TPPS), has been synthesized and applied to the determination of hydrogen peroxide. Under the optimum condition, the calibration graph has a linear range of 8.0 × 10-8 - 1.0 × 10-6 mol/l H2O2 with a detection limit (3σ, N = 9) of 5.3 × 10-9 mol/l.
