High entropy alloys (HEAs) are alloys that consist of five or more principal elements in nearequiatomic proportions that tend to form simple solid solutions during solidification, instead of inter-metallic compounds, owing to high mixing entropy . HEAs have been identified as promising candidates for various heterogeneous catalysis and electrocatalysis applications . For instance, Qiu et al. developed a nanoporous AlNiCuPtPdAu materials for the oxygen reduction reaction (ORR), important for metal-air batteries and fuel cells. The resulting catalyst exhibits greatly enhanced high temperature stability and have display redox activity up to ten times higher than the characteristics of Pt/C catalysts . For the CO2 reduction reaction (CO2RR), superior durable catalytic hydrogenation of CO2 was demonstrated using CoNiCuRuPd HEA nanoparticles . HEAs have also received much attention in recent years due to their unique mechanical properties, such as high strength and strain hardening ability . Additionally, HEAs have shown noteworthy chemical properties, including corrosion and oxidation resistance . The peculiar behaviourand often high performanceof HEA in various applications, is primarily attributed to four core effects .
