  • A research team from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has recently developed a Pt-based high-entropy-alloy (HEA) catalyst that significantly enhances the efficiency of propane dehydrogenation (PDH),

The article from Phys.org discusses a breakthrough in catalyst technology involving a high-entropy alloy (HEA) that significantly enhances the efficiency of the oxygen evolution reaction (OER) in water electrolysis. Researchers have developed a catalyst made from a mix of five transition metals (cobalt, iron, manganese, nickel, and zinc) which, when alloyed, exhibit superior catalytic activity compared to traditional single-metal catalysts. This HEA catalyst not only shows a lower overpotential for OER but also demonstrates remarkable stability and durability, maintaining its performance over extended periods. The unique properties of HEAs, such as high configurational entropy and lattice distortion, contribute to this enhanced performance by providing more active sites and improving the electronic structure for better reaction kinetics. This advancement could lead to more efficient and cost-effective hydrogen production, crucial for sustainable energy solutions.
