Advance of Prussian Blue‐Derived Nanohybrids in Energy Storage: Current Status and Perspective

Abstract

Great changes have occurred in the energy storage area in recent years as a result of rapid economic expansion. People have conducted substantial research on sustainable energy conversion and storage systems in order to mitigate the looming energy crisis. As a result, developing energy storage materials is critical. Materials with an open frame structure are known as Prussian blue analogs (PBAs). Anode materials for oxides, sulfides, selenides, phosphides, borides, and carbides have been extensively explored as anode materials in the field of energy conversion and storage in recent years. The advantages and disadvantages of oxides, sulfides, selenides, phosphides, borides, carbides, and other elements, as well as experimental methodologies and electrochemical properties, are discussed in this work. The findings reveal that employing oxides, sulfides, selenides, phosphides, borides, and other electrode materials to overcome the problems of low conductivity, excessive material loss, and low specific volume is ineffective. Therefore, this review intends to address the issues of diverse energy storage materials by combining multiple technologies to manufacture battery materials with low cost, large capacity, and extended service life.

Enhancing Oxygen Evolution Reaction Performance in Prussian Blue Analogues: Triple‐Play of Metal Exsolution, Hollow Interiors, and Anionic Regulation

“…Another strategy to enhance catalytic efficiency is by tuning the electronic properties of PBAs via doping. [21] In this context, anion regulation has been reported to enable highperforming PBA OER electrocatalysts by charge transfer, in addition to optimizing the adsorption/desorption response of oxygencontaining intermediates on the catalyst surface. [22,23] Based on this progress, we aimed to develop PBAs displaying superior OER efficiency and stability benchmarked against leading-edge electrocatalysts by combining hollow interiors, Ni NPs exsolution, and Se incorporation in a single synthetic step: one stone three birds strategy approach.…”

“…[179,180] These two methods are also used when using PBAs as precursors to synthesize transition metal sulfides. [181] Yu et al [122] successfully fabricated cubic NiS nanoframes using Ni-Co PBA as template for anion exchange with S 2− in Na 2 S at high temperature (Figure 13a). The different reactivities of Ni-Co PBA edges and planes were used for anisotropic etching.…”

Length-tunable Pd2Sn@Pt core–shell nanorods for enhanced ethanol electrooxidation with concurrent hydrogen production

“…Pt and Pt-based catalysts have been widely recognized as highly efficient electrocatalysts for the EOR. [29][30][31][32] However, their practical application is severely hindered by the exorbitant cost of Pt. Additionally, these catalysts oen suffer from rapid degradation during the EOR process due to the accumulation of carbonaceous intermediates on their surfaces.…”
