Electrochemical nitrogen reduction reaction (NRR) has emerged as a promising approach for sustainable ammonia synthesis under ambient conditions, offering low-energy alternative to the traditional Haber–Bosch process. However, development of efficient and electrocatalysts NRR remains significant challenge. Noble metals, known their exceptional chemical stability electrocatalytic have garnered considerable attention in this field. In study, we report successful nanoporous CuAuPtPd quasi-high-entropy alloy (quasi-HEA) prism arrays through “melt quenching” “dealloying” techniques. The as-obtained demonstrates remarkable performance an electrocatalyst, achieving impressive rate 17.5 μg h−1 mg−1 at potential −0.2 V vs. RHE, surpassing many previously reported catalysts. This work not only highlights quasi-HEAs advanced but also provides valuable insights into design multicomponent materials energy catalytic applications.

Green H2 production via electrochemical water splitting has emerged as a pivotal solution for achieving sustainable energy future. This Review delves into the fundamentals of splitting, focusing on O2 evolution reaction (OER) and (HER), focuses critical role electrocatalysts in these processes. Precious metals such paltinum iridium remain benchmarks catalytic performance; however, their scarcity high cost necessitate development alternative materials. Recent advances Earth-abundant catalysts, including transition-metal oxides, carbides, nitrides, sulfides, have shown promise balancing activity, durability, affordability. The integration nanostructuring techniques computational modeling enabled design catalysts with enhanced active site exposure electronic properties. Furthermore, highlights challenges material degradation, overpotentials, gas crossover, along potential solutions like protective coatings, bifunctional advanced electrolyzer designs. Future prospects emphasize artificial intelligence, hybrid systems, manufacturing accelerating progress. comprehensive review underscores significance bridging fundamental research technological innovations to scale up green hydrogen production, addressing demands while mitigating environmental impacts.

High entropy alloys (HEAs) have been widely studied due to their special crystal structure, but bulk structure and low specific surface area limit further application in broader fields. In this work, the dealloying of precious metal Cu35Pd35Ni25Ag5 quasi-HEAs is performed. Porous noble metals with micro prism array porous PdO/Ag2O/NiO oxides nano “ligament/pore” are obtained by constant potential free dealloying, respectively. way, porosification achieved. Moreover, effects parameters on pore morphology phase dealloyed materials studied, evolution mechanisms structures different products discussed. The work provides strategies for preparation method. These present great as functional hot fields such catalysis energy storage.
