Abstract Conventional alloys have long been limited by their simple compositions, which make it difficult to meet the requirements of modern catalysis applications. In contrast, high‐entropy (HEAs), characterized multi‐principal elements in near‐equimolar ratios, become a transformative paradigm materials science since inception 2004. The unique core effects HEAs, including effect, severe‐lattice distortion sluggish‐diffusion and cocktail endow them with superior catalytic properties activity, selectivity, durability. However, rapid advanced development comprehensive review applications is imperative foster deeper understanding. this review, capability commencing from entropy‐driven mechanism HEAs systematically explored. Then, are comprehensively analyzed diverse fields, energy conversion, chemical industries, environmental remediation, emphasizing remarkable capabilities Finally, pivotal challenges outlined synthesis methods, mechanistic elucidation, green manufacturing, propose future directions such as database establishment machine‐learning‐assisted design. By addressing knowledge gaps inspiring innovative strategies, aims accelerate translation into practical solutions for sustainable future.

Hydroxide exchange membranes (HEMs) have attracted extensive attention in energy-related fields, such as fuel cells and water electrolysis, primarily due to their suitability for alkaline environments. However, the practical application of is hindered significantly by limited conductivity. In this study, a series amphoteric metal ion-coordinated chitosan (CTS-AM) with enhanced hydroxide ion conductivity are reported. The CTS-AM prepared using simple soaking-drying method, exhibiting excellent mechanical strength thermal stability strong coordination bonds between ions chains. To best our knowledge, Zn2+ coordinated membrane achieved highest-ever reported 82.0 ± 5.4 mS cm-1 at 25 °C 100% RH, value increasing 301.0 6.7 operating temperature (80 °C) RH. Through combined structural analysis theoretical calculations, we propose that formation nanochannels lowered barrier electron transfer responsible high conductivities membranes. This study presents viable approach design fabrication high-performance HEMs energy storage devices other applications.
