We describe an electrochemical sensor for hydrogen peroxide (H 2 O 2 ) that is making use of Prussian Blue (PB) electrodeposited on a macroporous (mp) gold skeleton electrode. An mp-Cu film was first prepared as a template and the converted into an mp-Au film through a replacement reaction without destructing the structure. Next, a layer of PB was electrochemically deposited...
A hydrogen peroxide sensor based on a polypyrrole (PPy)/Prussian blue (PB) modified electrode was developed. PPy nanowires were prepared by one step template-free electrochemical polymerization on a gold electrode and a PB layer was deposited using an electrochemical method. The introduction of the PPy nanostructure can provide a high surface area and lead to high sensitivity to hydrogen peroxide...
