We used entropy engineering to design a series of CoFe2O4-type spinels. Through microstructural characterization, electrochemical measurements, and X-ray photoelectron spectroscopy, we demonstrated that the entropy-stabilized oxide (Co0.2Mn0.2Ni0.2Fe0.2Zn0.2)Fe2O4 has single-phase spinel structure exhibits both efficient stable catalytic oxygen evolution. This is attributable disordered occupation multivalent cations, which induces severe lattice distortion increases configurational entropy,...

The microstructures of high entropy alloys the system CoCrCuFe x Ni and CoCrCuFeNi (where indicates molar ratio, which, where not specified, is 1) have been investigated. Many Cu rich spheres were evident in microstructure 0.5 alloys, which that liquid phase separation had occurred before solidification. During separation, original liquids separated into two liquids: depleted. In contrast, other ( = 1.0, 1.5 2.0), typical dendritic interdendritic structures are obtained. and/or Cr...
Electrochemical splitting of water to hydrogen is widely considered as an efficient and sustainable solution relieve the energy crisis. In this work, we report a facile dealloying method based on metallic glass (Ni61Zr36Mo3) introduce abundant oxygen vacancies (Ov) for electrocatalytic evolution reaction (HER). The corroded ribbons are composed sandwich-like structure with Ni–Mo–O nanoporous layer outside raw inside. This complex delivers low overpotential 71 ± 2.6 mV at −20 mA cm–2geo in...
The NiCoFeCrAl3 high entropy alloy coating with a little addition of C, Si, Mn, Mo has been succesively synthesized by laser cladding. results show that simple solution phases ordered BCC and small fraction FCC are obtained fine equaixed dendrites morphology. Because the grain strengthening rapid solidification additived atomic elements like Si further increase distortion solid lattice, microhardness reached above 800 HV is 50 % higher than previous study on similar composition arc melting technique.
Highly active and robust electrocatalysts for the oxygen evolution reaction by intentional surface reconstruction of high-entropy amorphous alloys.
