Electrochemical preparation of a Prussian blue analog: iron-ruthenium cyanide

Abstract

Recent reports by Neff et al. have shown a method of preparation of Prussian blue (PB) on platinum and gold electrodes based on a chemical method.1•2 We disclosed very recently an elec-

Identification of electroactive sites in Prussian Yellow films

“…Neff on the surface of gold electrodes [10]. Some years later, in 1982 Itaya et al [3,[11][12][13][14] described a galvanostatic procedure to produce good and controlled quality PB films on different type of electrode substrate. In these works, it has been proved that some electrochemical properties are dependent on the rate of electrogeneration, obtaining narrower and sharper voltammetric peaks for the higher current deposited PB films.…”

Redox switching of Prussian blue thin films investigated by ac-electrogravimetry

“…Although it has been studied for 270 years, it is still a research topic of high interest because of its numerous interesting properties as electrochromism, ion exchanger, and photomagnetic properties which allow applications in electrocatalysis, electrochromic or electronic devices, and batteries. PB films can be generated by chemical [1][2] or electrochemical [3][4] ways, often from an aqueous solution of a FeCl 3 and K 3 Fe(CN) 6 mixture. PB was deposited at an electrode surface for the first time by V.D.…”

Cubic Copper Hexacyanoferrates Nanoparticles: Facile Template-Free Deposition and Electrocatalytic Sensing Towards Hydrazine

“…Figure 1(d) presents typical cyclic voltammograms of the CuHCFmodified GC electrode in these four different supporting electrolytes. According to the limiting mobility by Stokes' law, the radius of the hydrated Li + , Na + , K + , and NH 4 + is 2.1, 1.83, 1.25, and 1.25Å, respectively [17,18]. According to Figure 1(d) we may determine that the transfer order is K + > Li + > Na + > NH + 4 in the deposited CuHCF film.…”

“…Ever since the pioneering work of Neff [1] and Itaya et al [2] using Prussian blue (PB) modified electrodes, extensive electrochemical studies on PB [3][4][5] and its analogue modified electrodes, such as cobalt hexacyanoferrate (CoHCF), nickel hexacyanoferrate (NiHCF), copper hexacyanoferrate (CuHCF) have been of great interest to electrochemists due to their interesting properties, especially the ability to mediate electrochemical reactions such as electrocatalyzed oxidations; for example, they can be used in biosensing for the detection of glucose [6,7] and many other important analytes.…”
