Selective patterning of Prussian blue on N-[3-(trimethoxysilyl)propyl]ethylenediamine capped gold nanoparticle film for electrocatalysis of hydrogen peroxide reduction

In this work, we have demonstrated selective patterning of electrodes coated with N-[3-(trimethoxysilyl)propyl]ethylenediamine (EDAS) stabilised gold nanoparticles (Sil-AuNps) films with Prussian blue (PB) by continuous electrochemical cycling of Sil-AuNps film modified Indium Tin Oxide (ITO) electrode in K3[Fe(CN6)] solution. The PB formed on gold nanoparticles (PB@Sil-AuNps) exhibits an electrochemical response similar to the PB formed on a...
