Effect of the external metal on the electrochemical behavior of M3[Co(CN)6]2 (M: Co, Ni, Cu, Zn), towards their use as anodes in potassium ion batteries

Self-induced cobalt-derived hollow structure Prussian blue as a cathode for sodium-ion batteries

“…The intensity of the N-Fe chemical bond becomes weaker compared to the C-Fe chemical bond because the Fe-C-N-Fe functional group substitutes the Co-C-N-Fe functional group. [18][19][20] The above characterizations reveal that the bond energy of the Co-C-N group is weaker than that of the Fe-C-N group. This is the key point for the phase transition from Fe 3 [Co(CN) 6 ] 2 to Na 2 Fe[Fe(CN) 6 ].…”

Progress and challenges of Prussian blue analogs for potassium-ion batteries: a perspective on redox-active transition metals

“…PBAs are a general term for a class of transition metal cyanides, and their chemical formula can be represented by A x M [M ′ (CN) 6 ] y , 1−y $mH 2 O, where A is an alkali metal element (0 # x # 2); M is a transition metal element such as iron, manganese, cobalt, nickel, copper, and zinc; M ′ is usually iron, and , stands for vacancy. [51][52][53][54] It can be easily found that PBAs share a similar chemical formula with Prussian white analogs (PWAs), i.e., K x MFe(CN) 6 $mH 2 O (M = Fe, Co, Ni, or Cu). PWAs can be regarded as a subclass of PBAs, where the main difference between them is their content of potassium ions.…”

Progress in the preparation of Prussian blue-based nanomaterials for biomedical applications

“…The usually selected metals to replace Fe elements are: Mn, Co, Ni, Cu, Zn and so on. [78][79][80][81] Bimetallic PBA includes complexes where part of the Fe element in the framework is replaced or the Fe element is replaced by two other metals. Some representative ones are Ni-PBA, Co-PBA, and Mn-PBA, and there are many more.…”
