A New Preparation Method of Electrochromic Prussian Blue Films by Casting a Solution and Their Electrochemical Properties

Abstract

A novel method for preparing Prussian Blue (PB) films cast from a PB solution of organic solvent containing cationic surfactants is reported. The cyclic voltammogram for the oxidation of the film is much simpler than that of an electrochemically deposited PB film. The electrochromic behavior was investigated by in-situ UV-VIS spectroscopy.

Hydrogen peroxide detection using a polypyrrole/Prussian blue nanowire modified electrode

“…2 PB is an inorganic compound composed of iron and cyanide ions with the general formula KFe III [Fe II (CN) 6 ] or Fe III 4 [Fe II (CN) 6 ] 3 , which was synthesized for the first time by Diesbach 2 and is well known for its wide range of applications in the fields photoresponse, 3 electrochemistry, magnetism, 4 electrochromism, 5 electrocatalysis, 6 sensors, ion-exchanger materials, 7 and so on. Many methods of preparing PB have been reported, such as electrochemical deposition, 8 Langmuir-Blodgett deposition, 4 casting from a colloidal solution, 9 and the self-assembly technique. 10 Among these methods, electrochemical deposition is known to be the easiest and the most rapid, so, it can be used in the construction of extremely sensitive devices.…”

Amperometric determination of hydrazine using a surface modified nickel hexacyanoferrate graphite electrode fabricated following a new approach

“…Recently metal hexacyanoferrates have also found applications in electrochromism [15,16], electrocatalysis [17,18], ion exchange selectivity [19,20], corrosion protection [21], etc. Furthermore their ion exchange capacity makes them an interesting candidate to develop sensors and biosensors [22,23].…”

Synthesis and stabilization of Prussian blue nanoparticles and application for sensors

“…These special properties make PB-modified electrodes potentially applicable for sensors [5][6][7] or electrochromic display devices [8]. Several publications were already concerned with the characterization of these properties in thin films of PB [9][10][11][12][13][14][15][16], which were prepared by different methods from dip-coating to spray technique via Langmuir-Blodgett (LB) deposition [17][18][19][20][21][22] or SPR technique [23]. Among the different techniques of film preparation, only the LB technique was suitable so far to control the film thickness.…”
