An efficient and stable bifunctional oxygen catalyst is necessary to complete the application of rechargeable zinc-air battery. Herein, an economical convenient process was adopted successfully coat high-entropy alloy Fe12Ni23Cr10Co55–xMnx nanoparticles on carbon nanotubes (CNTs). In 0.1 M KOH solution, with a overpotential (ΔE) only 0.7 V, Fe12Ni23Cr10Co30Mn25/CNT exhibits excellent catalytic performance, exceeding most catalysts reported so far. addition, air electrode assembled this high specific capacity (760 mA h g–1) energy density (865.5 W kg–1) in liquid battery, long-term cycle stability over 256 h. The functional theory calculation points out that changing atomic ratio Co/Mn can change adsorption intermediate (*OOH), which allows ORR be accelerated alkaline environment, thereby increasing activity. This article has important implications for progress commercially available their applications batteries.

Abstract The production of hydrogen through water electrolysis (WE) from renewable electricity is set to revolutionise the energy sector that at present heavily dependent on fossil fuels. However, there still a pressing need develop advanced electrocatalysts able show high activity and withstand industrially-relevant operating conditions for prolonged period time. In this regard, entropy materials (HEMs), including alloys oxides, comprising five or more homogeneously distributed metal components, have emerged as new class owing their unique properties such low atomic diffusion, structural stability, wide variety adsorption energies multi-component synergy, making them promising catalysts challenging electrochemical reactions, those involved in WE. This review begins with brief overview about WE technologies short introduction HEMs synthesis general physicochemical properties, followed by nearly exhaustive summary reported so far evolution reaction, oxygen reaction overall splitting both alkaline acidic conditions. concludes an outlook future development HEM-based further research be done understand catalytic mechanism eventually deploy practical electrolysers.

This review focuses on thermodynamic and physical parameters, synthesis methods, reported phases of Magnesium (Mg) containing high-entropy alloys (HEAs). Statistical data publications concerning Mg-containing HEAs were collected analyzed. Data the chemical elements included in HEAs, their theoretical end experimental densities, fabricated techniques also discussed. On basis this information, a new classification for was proposed. It is shown that existing parameters cannot accurately predict formation single phase solid solution HEAs. The are within wide range, most synthesized have complex multiphase structure.
