“…Another interesting function of the as-prepared self-recoverable PB/Al cell is its potential use as a self-rechargeable battery. The measured open circuit potential of the PB/Al battery with 3 mol l À 1 KCl electrolyte is 1.26 V, which is significantly higher than that of previously reported EC materials-based batteries [27][28][29] . To light up a red light-emitting diode (LED), we connected two PB/Al cells in series, which can supply a voltage of 2.52 V. The LED is brightest when powered by the freshly prepared cells (Fig.…”

“…This interesting chemical property of PW, that is, spontaneously reverting to PB in the presence of oxygen 19,32 , has not previously attracted significant attention. Moreover, it is even generally regarded as a drawback in making a battery because it causes a reduction of the battery voltage 27 , and as a result, the battery needs to be isolated from air. However, here we make good use of this interesting property to prepare a selfrechargeable battery.…”

“…A similar electrode material of iron hexacyanochromate has also been used as an anode material for rechargeable batteries 30 . In brief, all the above-mentioned batteries [27][28][29][30][31] do not utilize the EC function of these EC materials, and their output voltage is relatively low. Like conventional batteries, they are not selfrechargeable and the charging relies on an external power source.…”

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

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.

“…copper hexacyanoferrate (CuHCF), as electrodes exhibit a number of merits; they can be synthesized in large quantities from cheap precursors and show long cycle lives, fast kinetics, high power operations, and good energy efficiencies [2]. There has been a burgeoning interest in Prussian blue (PB) and PBA compounds in the last decades for other applications as well; hydrogen storage [3], electrocatalysis [4], and charge storage [5], are a few examples from a large variety of fields. Their physical and chemical properties have been extensively studied by many experimental methods, e.g.…”

The kinetics of thermal dehydration of K 2x/3 Cu [Fe(CN) 6 ] 2/3 ÁnH 2 O was studied using thermogravimetry for x = 0.0 and 1.0. Data from both non-isothermal and isothermal measurements were used for model-free kinetic analysis by the Friedman and KAS methods. The water content was determined to be n = 2.9-3.9, plus an additional *10% of water, likely surface adsorbed, that leaves very fast when samples are exposed to a dry atmosphere. The determined average activation energy for 0.2 B a B 0.8 is 56 kJ mol -1 . The dehydration is adequately described as a diffusion-controlled single-step reaction following the D3 Jander model. The determined dehydration enthalpy is 11 kJ (mol H 2 O) -1 for x = 0.0 and 27 kJ (mol H 2 O) -1 for x = 1.0, relative to that of water. The increase with increasing x is evidence that the H 2 O molecules form bonds to the incorporated K ? ions.

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.
