Web23 de jun. de 2024 · High entropy alloys are the solid solutions with at least 5 principle elements with almost equal atomic ratio which varies from 5 to 35. The high statistical entropy in these alloys causes to the formation of simple solid solution phases of FCC, BCC, or a combination of both, or even an amorphous structure. WebThe introduction of high-entropy alloys with entropy-stabilization features has shown high potential for various functional applications in recent years. By considering these two types of materials, we developed a high-entropy oxynitride for photocatalytic water splitting.
