Iron-nickel hexacyanoferrate bilayer as an advanced electrocatalyst for H2O2 reduction

An advanced electrocatalyst for H2O2 reduction was synthesized via the deposition of an iron-and nickel hexacyanoferrate bilayer and displayed a similar electrocatalytic activity (approximate to 0.01 cm s(-1)) and an almost 100-fold improved operational stability compared to Prussian Blue. The electrocatalyst was highly reproducible, with a deviation in both the operational stability and catalytic activity among different modified electrodes of < 10%.
