چکیده
The family of dehydrated nanoporous Prussian Blue analogues, M(II)3[Co(III)(CN)6]2 (M(II) = Mn, Fe, Co, Ni, Cu, Zn, Cd), which contain coordinatively unsaturated divalent metal cations, undergoes reversible sorption of hydrogen gas up to 1.2 wt% (at 77 K, 101.3 kPa), the capacity of which depends on the metal ion.

Hydrogen storage in the dehydrated prussian blue analogues M3[Co(CN)6]2 (M = Mn, Fe, Co, Ni, Cu, Zn).
The porosity and hydrogen storage properties for the dehydrated Prussian blue analogues M3[Co(CN)6]2 (M = Mn, Fe, Co, Ni, Cu, Zn) are reported. Argon sorption isotherms measured at 87 K afford BET surface areas ranging from 560 m2/g for Ni3[Co(CN)6]2 to 870 m2/g for Mn3[Co(CN)6]2; the latter value is comparable to the highest surface area reported for any known zeolite. All six compounds show s...
متن کاملPrussian blue analogues Mn[Fe(CN)6]0.6667·nH2O cubes as an anode material for lithium-ion batteries.
In the present work, Prussian blue analogues, Mn[Fe(CN)6]0.6667·nH2O (Mn-PBA), were synthesized by a simple synthetic route and characterized by XRD, SEM, TEM, FTIR and TGA. When this material was firstly used as an anode for lithium-ion batteries, it exhibited a large capacity, good rate capability and cycling stability with a high Coulombic efficiency. For instance, a reversible capacity of 2...
متن کاملPrussian blue: a new framework of electrode materials for sodium batteries.
Prussian blue and its analogues consisting of different transition-metal ions (Fe, Mn, Ni, Cu, Co and Zn) have been synthesized at room temperature. Insertion of Na into KFe(2)(CN)(6) in a carbonate electrolyte exhibited a reversible capacity near 100 mA h g(-1) with no capacity fade in 30 cycles. The data indicate that a Na-ion battery with a Prussian blue framework as a cathode will be feasible.

The electronic spectra, electrical conductivity, magnetism, and gas adsorption properties of the newly prepared Prussian blue analogues Fe4[Ru(CN)6]3 · 18H2O (2) and K1.2Ru3.6[Ru(CN)6]3 · 16H2O (3) are compared with those of Prussian blue itself (Fe4[Fe(CN)6]3 ·14H2O, 1). The increase in the degree of electronic localization for the unsymmetrical iron-ruthenium analogue 2 is reflected in a shif...
متن کاملThe role of vacancies in the hydrogen storage properties of Prussian blue analogues
The porosity and hydrogen storage properties of the dehydrated Prussian blue type solids Ga[Co(CN)6], Fe4[Fe(CN)6]3, M2[Fe(CN)6] (M = Mn, Co, Ni, Cu), and Co3[Co(CN)5]2 are reported and compared to those of M3[Co(CN)6]2 (M = Mn, Fe, Co, Ni, Cu, Zn). Nitrogen sorption measurements suggest partial framework collapse for M2[Fe(CN)6] (M = Co, Ni) and Co3[Co(CN)5]2, and complete collapse for Mn2[Fe(...
