Summary: Electrolytic water, metal-air cells, and fuel cells are key areas in the application of new energy. Developing highly active electrocatalysts is essential to overcome the limitations of oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) in these fields. Prussian blue analogues (PBAs) have been widely used in ORR, OER, and HER due to their unique structure and large specific surface area. This review summarizes the recent progress of PBAs derived materials in electrocatalysis, including different preparation methods, regulatory strategies to improve the electrocatalytic activity, and future research directions.

Summary: The microstructure of materials plays a significant role in their performance. Hollow-structure materials, as electrocatalysts, exhibit better performance due to their larger specific surface area, lower density, and more exposed active sites. Bimetallic catalysts, compared to monometallic catalysts, have superior catalytic activity due to synergistic effects between different metal elements. Prussian blue and its analogues are ideal precursors for preparing hollow-structure bimetallic catalysts. In this study, hierarchical hollow CoFePBA was prepared using ZIF-67 hollow sphere as a template, and its oxygen evolution reaction catalytic performance was further improved through low-temperature heat treatment.

Summary: This study reveals the process of K' being replaced by NH4' in CoFe PBA and its influence on the transformation and OER performance of the derivatives. It is found that CoFe alloy nanoparticles grow on the crystalline cubes of CoFe PBA with K', while cubes with NH4' become amorphous after heat treatment. Furthermore, the derivative with NH4' exhibits better OER performance compared to the derivative with K'. A single-cell alkaline electrolyzer using Ar-U-CoFe PBA and Pt/C catalysts achieves a current density of 100 mA cm-2 at 1.66 V and shows negligible degradation after 100 hours.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
