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

et al. 2013

View full text Add to dashboard Cite

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.

Is the Hexacyanoferrate(II) Anion Stable in Aqueous Solution? A Combined Theoretical and Experimental Study

et al. 2015

A combined theoretical and experimental study has been performed to elucidate the structural and dynamical properties of aqueous hexacyanoferrate(II) isolated and in presence of potassium ions. It is shown that in absence of counter ions, the highly negatively charged hexacyanoferrate(II) complex is not stable in aqueous solution.However, if the high negative charge is compensated by potassium counter ions, a stable complex is observed, which is proven by theoretical simulations as well as by EXAFS experiments. From the simulation it is found that potassium ions surrounding the complex are highly mobile and thus, cannot be observed in the experiment. The structure of aqueous hexacyanoferrate(II) in presence of potassium ions is identical to that of the solid state structure, but the mobility of potassium ions is significantly increased in the liquid. These highly mobile potassium ions circulating the complex should be the reason for the very short hydrogen bond lifetimes in the femtosecond range of the cyanide ligands.

“…1a). Each unit cell consists of eight subunit cells and therefore contains eight interstitial sites that can host various ions, such as Li þ , Na þ , K þ , NH 4 þ , Rb þ , alkaline earth divalent ions and zeolitic water 16,17 . The open-framework nature of the cubic structure, which contains open o1004 channels (3.2 Å in diameter) and interstitial sites (4.6 Å in diameter) in the case of Prussian Blue 18 , enables rapid solid-state diffusion of a wide variety of ions.…”

Manganese hexacyanomanganate open framework as a high-capacity positive electrode material for sodium-ion batteries

et al. 2014

View full text Add to dashboard Cite

Potential applications of sodium-ion batteries in grid-scale energy storage, portable electronics and electric vehicles have revitalized research interest in these batteries. However, the performance of sodium-ion electrode materials has not been competitive with that of lithium-ion electrode materials. Here we present sodium manganese hexacyanomanganate (Na 2 Mn II [Mn II (CN) 6 ]), an open-framework crystal structure material, as a viable positive electrode for sodium-ion batteries. We demonstrate a high discharge capacity of 209 mAh g À 1 at C/5 (40 mA g À 1 ) and excellent capacity retention at high rates in a propylene carbonate electrolyte. We provide chemical and structural evidence for the unprecedented storage of 50% more sodium cations than previously thought possible during electrochemical cycling. These results represent a step forward in the development of sodium-ion batteries.
