Electrocatalytic trends of different Cantor entropy alloys for alkaline and acidic hydrogen-evolution reactions [Elektronski vir]Ljubec Božiček, Barbara ...Medium- and high-entropy alloys (MEAs and HEAs) are the basis of unique electrocatalysts for hydrogen-evolution reactions (HERs) due to their tunable chemical compositions and microstructures. Here, ... various Cantor MEAs (CoFeNi, CoFeNiMn, CoFeNiCr) and a HEA (CoFeNiMnCr) made up of affordable non-noble transitional metals with different structures (primary matrix and secondary phases, grain sizes, lattice parameters) were successfully synthesized with an inert-gas melting process. A close correlation was established between their physicochemical properties (elemental composition, microstructure, crystal structure) and the hydrogen-binding ability of the elements in the alloy on the electrocatalytic HER activity and stability in alkaline and acidic media. Advanced performances of electrocatalysts toward HERs were revealed in a specially designed electrochemical cell. Effectively identifying these electrocatalytic trends lays the groundwork for the strategic design of multi-component alloy electrocatalysts for practical HERs.Source: Materials today communications [Elektronski vir]. - ISSN 2352-4928 (Vol. 41, [article no.] 110876, Dec. 2024, str. 1-7)Type of material - e-article ; adult, seriousPublish date - 2024Language - englishCOBISS.SI-ID - 214436867
