From: The Intrinsic Enzyme Activities of the Classic Polyoxometalates

Comparison of enzyme mimic activities of polyoxometalates. (a) peroxidase-like activities with TMB or OPD as substrate. (b) oxidase-like activities with TMB or OPD as substrate. Conditions: 200 μM POMs, 200 mM H2O2 at room temperature for 10 minutes in the optimum pH.
