Abstract: A catalytic structure has a plurality of high-entropy alloy (HEA) nanoparticles. Each HEA nanoparticle is composed of a homogeneous mixture of elements of cobalt (Co), molybdenum (Mo), and at least two transition metal elements. For example, in some embodiments, each HEA nanoparticle is a quinary mixture of Co, Mo, iron (Fe), nickel (Ni), and copper (Cu). The homogeneous mixture in each HEA nanoparticle forms a single solid-solution phase. The catalytic structure is used to catalyze a chemical reaction, for example, ammonia decomposition or ammonia synthesis. Methods for forming the catalytic structure are also disclosed.
