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.…”

Abstract.Prussian Blue films were electrogenerated on the surface of the transparent ITO electrodes. The electrochemical oxidation to the Prussian Yellow form was investigated by means of in situ voltammetry and Vis-NIR spectroscopic techniques. Changes of the whole spectra between 400 and 950 nm were analyzed and three characteristic wavelengths were selected to in situ follow the electrochemical changes of the films.Voltammetric peaks and absorbance derivative curves at these three wavelengths were deconvoluted and were interpreted such as the overlapping of different electrochemical processes. The correlation between these overlapped processes has allowed proposing three different electrochemical processes for the interpretation of the whole electrochemical response. One of these processes corresponds to the oxidation of

“…As one of known EC materials, iron(II,III) hexacyanoferrate(II,III), commonly known as Prussian blue (PB), is a coordination compound and has long been used as a blue pigment [17][18][19][20] . The application of PB as an EC material was pioneered by Neff and coworkers 21,22 and Itaya et al [23][24][25] PB can be reduced to colourless 'Everitt's Salt' (Prussian white (PW)), oxidized to Berlin green and 'Prussian yellow' by electrochemical reactions 21,26 . Neff 27 also studied a PB battery in which both the anode and cathode are PB films electrochemically deposited on porous graphite, and an improved battery using PB and Nafion composite was also reported by Honda et al 28 However, the Neff cell has a low theoretical output voltage of 0.68 V, and the voltage of the charged battery continually drops in air due to the oxidation of PW to PB.…”

A bi-functional device for self-powered electrochromic window and self-rechargeable transparent battery applications

et al. 2014

Electrochromic smart windows are regarded as a good choice for green buildings. However, conventional devices need external biases to operate, which causes additional energy consumption. Here we report a self-powered electrochromic window, which can be used as a self-rechargeable battery. We use aluminium to reduce Prussian blue (PB, blue in colour) to Prussian white (PW, colourless) in potassium chloride electrolyte, realizing a device capable of self-bleaching. Interestingly, the device can be self-recovered (gaining blue appearance again) by simply disconnecting the aluminium and PB electrodes, which is due to the spontaneous oxidation of PW to PB by the dissolved oxygen in aqueous solution. The self-operated bleaching and colouration suggest another important function of the device: a self-rechargeable transparent battery. Thus the PB/aluminium device we report here is bifunctional, that is, it is a self-powered electrochromic window as well as a self-rechargeable transparent battery.

Filmes de azul da Prússia foram superficialmente depositados em eletrodos de pasta de carbono a partir de soluções contendo 2,0 x 10 -3 mol L -1 de K 3 [Fe(CN) 6 ], 3,0 x 10 -3 mol L -1 FeCl 3 e 1,0 x 10 -2 mol L -1 HCl, usando dois potenciais controlados. Para aumentar a estabilidade do eletrodo modificado, efetuaram-se 50 ciclos em solução contendo 1,0 x 10 -3 mol L -1 de RhCl 3 , 0,50 mol L -1 de KCl e 1,0 x 10 -2 mol L -1 de HCl no intervalo de -0,40 a + 0,60 V a 60 mVs -1 . Estes eletrodos, denominados de Rh-PBMCPE, apresentaram boa estabilidade durante a determinação amperométrica de H 2 O 2 a 0,040 V sem a interferência dos ácidos ascórbico e úrico. A corrente de redução variou linearmente com a concentração de H 2 O 2 no intervalo de 5,0 x 10 -5 a 8,6 x 10 -4 mol L -1 . O limite de detecção foi de 2,8 x 10 -5 mol L -1 com sensibilidade variando de 1,32 a 0,96 A mol -1 L cm -2 ao longo de cinco dias (180 determinações).Prussian Blue was deposited at carbon paste electrode surface from a solution containing 2.0 x 10 -3 mol L -1 K 3 [Fe(CN) 6 ], 3.0 x 10 -3 mol L -1 FeCl 3 and 1.0 x 10 -2 mol L -1 HCl using two controlled potentials. To improve the stability of the modified electrode it was 50 times cycled in a solution containing 1.0 x 10 -3 mol L -1 RhCl 3 , 0.50 mol L -1 KCl and 0.010 mol L -1 HCl in the potential range from -0.40 V to 0.60 V at 60 mV s -1 . The Rh -Prussian Blue carbon paste modified electrode (Rh-PBMCPE) showed good stability during amperometric catalytic determination of H 2 O 2 at 0.040 V, without ascorbic and uric acids interferences. The current changed linearly with H 2 O 2 concentrations in the range of 5.0 x 10 -5 -8.6 x 10 -4 mol L -1. The estimated detection limit was 2.8 x 10 -5 mol L -1 with sensibility changing from 1.32 to 0.96 A mol -1 L cm -2 along five days (180 determinations).Keywords: prussian blue, rhodium, carbon paste electrode, hydrogen peroxide, amperometry IntroductionPrussian Blue modified electrodes (PBME) have been prepared by electrochemical techniques on electrodes such as glassy carbon, 1-18 platinum, 1,3,19,[20][21][22][23] tin oxide, 1,3,[24][25][26] gold, 3 graphite, 27-28 titanium-silver-gold arrays, 29 basal pyrolytic graphite, 30 screen printed carbon ink interdigital arrays, 20 conducting polymer coated microelectrode arrays, 31 carbon fiber, 32 carbon paste, 33 etc.They were used to design new glucose, [8][9][10]17,21,23,28,30,32 alanine, 30 alcohol 30 and glutamate 13,14 biosensors based on the electrochemical detection of hydrogen peroxide, which is formed in the course of the substrate enzyme-catalyzed oxidation.
