“…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

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.

“…1b) as described in the "Experimental" section. The CV characteristics of PB film have been already studied [31][32][33][34]. By this comparison, the peak systems can be ascribed to the reversible redox reactions 1 (AA' system) and 2 (CC' system) [42,43].…”

Nafion® as advanced immobilisation substrate for the voltammetric analysis of electroactive microparticles: the case of some artistic colouring agents

et al. 2013

Voltammetry of microparticles is applied to characterise and to identify solid analytes of interest in the field of cultural heritage. Nafion® is used for the immobilisation of solid microparticles onto the surface of a glassy carbon electrode by exploiting the deposition onto the electrode surface of a micro-volume of a suspension of the microsample in polymeric solution. Cyclic voltammetry and square wave voltammetry are applied to characterise and to identify the microparticles immobilised in the Nafion® coating. The analyte studied in this work is Prussian Blue as a typical inorganic pigment, with a relatively simple electrochemical behaviour. The proposed method is applied to a sample of Venetian marmorino plaster. The performance of Nafion® for this analysis is compared with that of the polymer Paraloid B72.

“…It is well known that hydrazine is volatile and toxic and is easily absorbed by oral, dermal, or inhalation routes of exposure. Adverse health effects on people living near hazardous waste sites caused by hydrazine and its derivatives have been explored in detail [10], and the maximum recommended level of hydrazine is 1 ppm in trade effluents [11]. For these reasons, it is urgently required to provide a sensitive method for the determination of hydrazine in waste water and soil.…”

Cubic copper hexacyanoferrate (CuHCF) nanoparticles prepared via electrolytic deposition are presented with their morphology and crystalline structure characterized with SEM and XRD. The advantage of this methodology is that it allows the fabrication of uniform cubic nanoparticles with permeable structures onto the desired underlying electrode substrate. It was observed that the CuHCF film acts as a permeable membrane for cations such as K + , Na + , Li + , and NH 4 + with a selection order of K + > Li + > NH 4 + > Na + . Furthermore, the analytical utility of these cubic-like CuHCF morphologies supported on a glassy carbon electrode was evaluated towards the electrochemical oxidation of hydrazine which was found to exhibit a linear response over the range 66 μM to 17 mM with a detection limit corresponding to 16.5 μM.
