Rational Design and Engineering of Nanomaterials Derived from Prussian Blue and Its Analogs for Electrochemical Water Splitting

Abstract

Electrochemical water splitting (EWS) is a sustainable and promising technology for producing hydrogen as an ideal energy carrier to address environmental and energy issues. Developing highly‐efficient electrocatalysts for hydrogen and oxygen evolution reactions (HER and OER) is critical for increasing the efficiency of water electrolysis. Recently, nanomaterials derived from Prussian blue (PB) and its analogs (PBA) have received increasing attention in EWS applications owing to their unique composition and structure properties. In this Minireview, the latest progress of PB/PBA‐derived materials for EWS is presented. Firstly, the catalyst design principles and the advantages of preparing electrocatalysts with PB/PBA as precursors are briefly introduced. Then, strategies for enhancing the electrocatalytic performance (HER, OER or overall water splitting) were discussed in detail, and the recent development and applications of PB/PBA‐derived catalysts for EWS were summarized. Finally, major challenges and possible future trends related to PB/PBA‐derived functional materials are proposed.

Nanoheterostructures based on nanosized Prussian blue and its Analogues: Design, properties and applications

“…[278] It can also be mentionned that they can be converted into many other interesting compounds relevant for such application. [279] However, despite much progress has been made, there are very few PBAs and their derived materials that combine the advantages of all performance indicators such as facile preparation, low-cost, excellent electrochemical performance including tow overpotential, hich catalytic current density, and high stability. [280] In connection with the search for alternative solutions to these limitations, several discrete nanoheterostructures combining PBAs, such as MnFe-PBA, [251] CoFe-PBA, [195], [236], [281] or NiFe-PBA [195], [196], [281] with other inorganic materials for instance gold, [281] platinum, [195], [196] CoS2 [236] or POM [251] were developed to afford such active electrocatalysts for OER [236] [195] [251] or HER.…”

The High Electrocatalytic Performance of NiFeSe/CFP for Hydrogen Evolution Reaction Derived from a Prussian Blue Analogue

“…Despite widely used MOFs such as ZIF [22,24,25] and MIL [26,27] as precursors, Prussian blue analogues (PBAs) are a kind of MOF with a relatively low price. It has been demonstrated that the construction of three-dimensional (3D) architectures from TMC nanomaterials prepared with PBAs as a template also effectively boosted the HER activity due to their relative abundance of highly active sites brought about by high porosity [28][29][30].…”

In‐Situ Activated NiFePBA‐FeOOH Electrocatalyst for Oxygen Evolution Reaction and Zinc‐Air Battery

“…However, the sluggish four electrons process of OER still hinders the practical applications of new energy technology in green and sustainable energy conversion and energy storage. [1,2] In this regard, the exploration of highly efficient and affordable OER catalysts is of great significance. Generally, precious metal materials such as iridium (Ir), ruthenium (Ru) and their oxides (IrO 2 and RuO 2 ) are recognized as highly active catalysts.…”

“…The oxygen evolution reaction (OER) is of vital importance for the development of metal‐air batteries, electrochemical water splitting and fuel cells.
