Spontaneous precipitation pattern formation by crystallites of Mn–Fe-based Prussian blue analogues in agarose gel

Abstract: Precipitation patterns spontaneously formed by Mn–Fe PBAs in agarose gel were investigated over wide concentrations ranges for the outer (0.10 ≤ [Mn2+] ≤ 0.70 M) and inner electrolytes (0.01 ≤ [[Fe(CN)6]3−] ≤ 0.35 M) by visual/SEM observations.

“…4(a) are basically similar to the results reported in previous studies. [28][29][30] This image confirms that Mn-Fe PBAs form discrete precipitation bands in agarose gel, although their number is minimal, and their bandwidths are broad. In accordance with this observation, the ED-XRF distributions in Fig.…”

“…Generally, the properties of Prussian blue analogues (PBA) are strongly influenced by the Fe(CN)6 vacancies, which are correlated with the crystal structure, crystallite morphology, and preparation processes [19][20][21][22]. Interestingly, the sizes and shapes of Mn-Fe-based PBA (Mn-Fe PBA) crystallites in Liesegang bands have been reported to depend on the band position [23]. Therefore, if Liesegang band-like periodic patterns of Cu-Fe PBA form in the proposed setup, they have the potential to be used for producing Cu-Fe PBA crystallites varying in size and shape (i.e., having different functional properties) simultaneously, and, subsequently, the periodic bands of interest could be cut out and examined/applied specifically.…”
