Аннотация:We report that an advanced electrocatalyst for hydrogen peroxide reduction was synthesized. This uses Prussian Blue, which is known to be 1000 times more active and selective than platinum in this reaction and has already found applications in H2O2 fuel cells; however, it suffers from poor operational stability. On the contrary, the reported PB–nickel hexacyanoferrate (NiHCF) bilayer is characterized by a tremendously improved operational stability, retaining its catalytic activity at a similar level to PB's high level (with an electrochemical constant of 0.01 cm s-1). The PB–NiHCF bilayer is highly reproducible: deviations in both operational stability and catalytic activity of the final hybrid material are <10%, thus confirming its technological value. The superior characteristics of the electrocatalyst could open new horizons for hydrogen peroxide fuel cells. Alternatively, the electrocatalyst for H2O2 reduction could find applications in the elaboration of novel sensors and biosensors.
