“…S-ECD has slightly longer switching times than those of L-ECD (NaClO 4 ), presumably due to the smaller ionic conductivity of polymer electrolyte. 59,61,62 The dynamic transmittance response of polyFe/ITO ECD in Figure S13 of SI each individually corresponds to a potential bias of 2.2 and 2.5 V. As summarized in Table 1, this ECD exhibits relatively long switching times of 7.68 s in bleaching and 1.67 s in coloring at 2.5 V. This result highlights the importance of using a counter electrode to store/release ions to balance the reaction occurring on the working electrode according to eq 4, thus leading to more facile kinetics with shorter switching times. L-ECD (NaClO 4 ) and S-ECD are favorable as far as the switching times are concerned for potential applications in EC displays.…”

Durable electrochromic devices (ECDs) driven at 0.8 V were successfully fabricated by the complementary chromic combination of Fe(II)-based metallo-supramolecular polymer (polyFe) and Prussian blue analogues (PBAs). PolyFe was synthesized by the 1:1 complexing of Fe(OAc)2 and bis(terpyridyl)benzene and served as a cathodically coloring material. Nickel hexacyanoferrate (NiHCF) was revealed to be the best anodically coloring material among three PBAs. The complementary electrochromic (EC) pair of polyFe and NiHCF enabled a dramatic decrease of the driving voltage down to 0.8 V in the ECD. We fabricated two ECDs with liquid or solid electrolytes (L-ECD and S-ECD, respectively) and compared their EC properties. S-ECD showed a color change from blue-purple (0 V) to light yellow (0.8 V) with a transmittance change (ΔT) of 45.1% at 580 nm; the response times were 0.52 s for coloring and 1.03 s for bleaching; the coloration efficiency reached a high value of 627.5 cm2/C. S-ECD showed better durability than L-ECD in the long term stability test up to 10 000 cycles. In addition, a drastic change in transmittance spectrum between 415 and 655 nm in S-ECD aligned with the highest solar irradiance in the visible region. When exposing the S-ECD to solar irradiation, it was calculated that a large solar irradiance (99.6 W/m2) can be attenuated at the colored state (0 V), and only a low power density (0.0243 W/m2) was required to keep at the bleached state (0.8 V).

“…In particular, NiHCF is characterized by well-defined, reversible and reproducible responses in supporting electrolytes containing not only potassium but also other alkali metal cations such as lithium, sodium, rubidium or cesium [33,37,38]. In comparison to other metal hexacyanoferrates, NiHCF can be viewed as an active cation-exchange matrix [39] since both oxidized and reduced NiHCF structures permit unimpeded transport of electrolyte cations of different sizes while providing charge balance during the systems redox reaction.…”

A chemically modified electrode was successfully fabricated by means of depositing a thin layer of nickel hexacyanoferrate (NiHCF) on an amine adsorbed graphite paraffin wax composite electrode using a new approach. The electrode was further coated with Nafion. The electrochemical characteristics of the modified electrode were studied using cyclic voltammetry and electrochemical impedance spectroscopy (EIS). The modified electrode catalyzed dopamine (DA) oxidation in the concentration range of 1.5 Â 10 À6 to 1.2 Â 10 À3 M without the interference from ascorbic acid (AA). A detection limit of 4.9 Â 10 À7 M was obtained for DA in the presence of AA with a correlation coefficient of 0.9972 based on S/N ¼ 3. Flow injection analysis was used for the determination of dopamine with excellent reproducible results. The analytical utility of the sensor was evaluated for detection of DA in urine.

Mechanism for Interplay between Electron and Ionic Fluxes in K_hFe_k[Fe(CN)₆]_l·mH₂O Compounds

This paper develops a framework for the interpretation of ionic insertion/deinsertion reactions in an aqueous environment taking place in transition-metal hexacyanoferrates of the general formula K(h)[Fe(2+) (CN)(6)](l).mH(2)O, also called Prussian Blue. Three different processes were fully separated in the electrochemistry of these films. It was clearly identified that one of these electrochemical processes involves the insertion/deinsertion of H(3)O(+) (hydrated protons) through the channels of the K(h)[Fe(2+) (CN)(6)](l).mH(2)O structure to reach the film electroneutrality during the electron transfer between Everitt's Salt and Prussian Blue. The other electrochemical processes involve K(+) or H(+) (proton) exchange through the water crystalline structure existing in the channels of the K(h)[Fe(2+)(CN)(6)](l).mH(2)O structure.
