Jan 20, 2023 · In the current study, we synthesized Prussian blue analogues, K x Fe [Fe (CN) 6] (KFeHCF) having different [Fe (CN) 6] vacancies, potassium contents (x), and crystal system, and investigated the effect of the difference on ion-sensor performance by using the KFeHCF as the solid-contact layer of all-solid-state ion-selective electrodes (ASS-ISEs).

Oct 1, 2021 · In this paper, we describe the synthesis of PB and use X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and X-ray absorption spectroscopy to characterize the oxidation state and local structure of Fe in PB and two of its commercially obtained analogues, namely, K 4 Fe (CN) 6 ·3H 2 O and K 3 Fe (CN) 6.
