Prussian Blue Analogs and Their Derived Nanomaterials for Electrochemical Energy Storage and Electrocatalysis

Abstract

Prussian blue analogs (PBAs), the oldest artificial cyanide‐based coordination polymers, possess open framework structures, large specific surface areas, uniform metal active sites, and tunable composition, showing significant perspective in electrochemical energy storage. These electrochemically active materials have also been converted to various functional metal containing nanomaterials, including carbon encapsulated metals/metal alloys, metal oxides, metal sulfides, metal phosphides, etc. originating from the multi‐element compositions as well as elaborate structure design. In this paper, a comprehensive review will be presented on the recent progresses in the development of PBA frameworks and their derivatives based electrode materials and electrocatalysts for electrochemical energy storage and conversion. In particular, it will focus on the synthesis of representative nanostructures, the structure design, and figure out the correlation between nanomaterials structure and electrochemical performance. Lastly, critical scientific challenges in this research area are also discussed and perspective directions for the future research in this field are provided, in order to provide a brand new vision into the further development of novel active materials for the next‐generation advanced electrochemical devices.

Interface Engineering in CoP/CePO4 Derived from a Prussian Blue Analogue as a Highly Efficient Electrocatalyst for Alkaline Hydrogen Evolution Reaction

“…MOF‐derived materials, usually possessing abundant metal sites and large surface area, would promote activity in electrochemical reaction. Prussian blue analogues (PBAs) as typical MOFs are worthy to be investigated for their synthetic ease, low cost, feasibly derived to nanomaterials with tunable composition and structures [26] . The CoP nanoframes through the conversion from Co‐PBA precursor showed remarkable electrocatalytic activity toward HER and even overall water splitting reaction [27] .…”

Isopropyl alcohol and copper hexacyanoferrate boost performance of the iron tris‐bipyridine catholyte for near‐neutral pH aqueous redox flow batteries

“…The dimer reverts to its original lower reduction potential in quiescent solutions during post-mortem CV of the catholyte (-Figure S8). Prussian Blue analogs (PBAs) are known to demonstrate electrocatalytic activity towards several substrates, [67][68][69] however, to our knowledge, this is the first demonstration of their electrocatalytic effect toward an organometallic species. It is likely that this effect can be further enhanced by optimizing parameters such as CuHCF concentration, particle size, conductivity, and delivery method (ie, suspension vs direct electrode coating).…”

Electrochemical Signal Substance for Multiplexed Immunosensing Interface Construction: A Mini Review

“…Prussian blue (PB) nanoparticles, an iron-based nanomaterial, also serve as an inherent electrochemical activity [ 72 , 73 ]. Since Neff firstly reported the electrochemical behavior of PB and the successful deposition of a thin layer of PB on a platinum foil in 1978 [ 74 ], the wide application of PB has been promoted in various construction of electrochemical immunosensing interface, especially for its development in multiplexed electrochemical immunoassay [ 75 , 76 ].…”
