High-entropy-alloy nanoparticles
High-entropy-alloy nanoparticles (HEA-NPs) are nanoparticles having four or more elements alloyed in a single-phase solid solution structure.[1] HEA-NPs possess a wide range of compositional library, distinct alloy mixing structure, and nanoscale size effect, giving them huge potential in catalysis, energy, environmental, and biomedical applications.
Enabling synthesis
HEA-NPs are a structural analog to bulk high-entropy alloys (HEAs),[2][3] but synthesized at the nanoscale. The formation of HEAs requires high temperature for multi-element mixing; however, high temperature acts against nano-material synthesis due to high-temperature-induced structure aggregation and surface reconstruction.
In 2018, HEA-NPs were firstly synthesized by a carbothermal shock synthesis.[1] The carbothermal shock employs a rapid high-temperature heating (e.g. 2000 K, in 55 ms) to enable the non-equilibrium synthesis of HEA-NPs with uniform size and homogeneous mixing despite containing immiscible combinations. The material and technology are also patented.[4][5] Later, other similar non-equilibrium "shock" methods were also introduced to synthesize HEA-NPs and other types of high entropy nanostructures.[6][7][8]
Properties and applications
HEA-NPs have a large compositional library, which enables tunability in chemical composition, structure, and associated properties. In addition, owing to the high entropy structure, HEA-NPs typically show improved structural stability. With the above merits, HEA-NPs have been used as high-performance catalysts for both thermochemical and electrochemical reactions, such as ammonia oxidation, decomposition, and water splitting.[1][9][10][11] High throughput and data mining approaches toward accelerated material discovery in the multi-dimensional space on HEA-NPs.[12][13]
