Summary:
Multimetallic particles combining at least five dissimilar elements within a single structure, also known as high-entropy-alloy (HEA) nanoparticles, have recently received significant attention due to their advantageous physicochemical properties for broad applications in energy and catalysis. In this seminar, I will briefly discuss our group’s motivations, research overview, and selective achievements on the synthesis and manufacturing of high entropy materials including: (1) Extreme high temperature (2000–3000 K) thermal shock as a disruptive platform to design/synthesize high entropy nanoparticles (Science 2018, 359, 1489, Cover); (2) Continuous synthesis of high entropy nanoparticles by “droplet-to-particle” methods (Materials Today, 2020, 35, 106-114); (3) Continuous synthesis of morphology-controlled hollow high entropy alloy nanoparticles (Advanced Materials, 2020, 32, 2002853, Cover); (4) Continuous synthesis of composition-controlled high-entropy phosphate (Nano Energy 86, 106029). The manufacturing process is highly reproducible, scalable, and can generally be applied to a range of materials.
