Formation mechanisms of hollow manganese hexacyanoferrate particles and construction of a multiple-shell structure

Abstract

The core's preferential dissolution transforms the cubic-core/monoclinic-shell manganese hexacyanoferrate particles into the hollow structure. Applying an additional growth technique, multi-shell hollow particles have also been constructed.

Self-organized formation of seven-rod bundle morphology for lanthanum Prussian blue analog microcrystals via a precipitation process

“…Since PBAs possibly have compositions deviating from the stoichiometric formulae, 14 the elemental composition of the present microcrystals was evaluated by dissolving the freezedried powder in HNO 3 to apply the AAS (K + and [Fe(CN) 6 ] 4− ) and colorimetry (La 3+ ) measurements. The estimated composition formula is K 0.82 La 1.11 [Fe(CN) 6 ], which seems to be in the reasonable range of experimental estimation for the ions, as the total cation valence (+4.17) is close to the anion valence (−4).…”
