Over the last 28 years, our laboratory has focused on the designed chemical synthesis and assembly of uniform-sized nanocrystals and related nanomaterials, and their biomedical, energy and soft-electronic-device applications. Especially, we invented the “heat-up process”, a simple and reproducible method to produce large quantity of uniform-sized nanoparticles (Nat. Mater. 2004, 3, 891). We fabricated ultra-flexible and/or stretchable soft-electronic quantum-dot light-emitting diodes (QLEDs) (Nat. Elec. 2021, 4, 671 & 2024, 7, 365). For the last decade, our group has developed several synthetic methods to produce single-atom catalysts and nanocatalysts for photocatalytic (Nat. Mater. 2024, 23, 552; Nat. Nano. 2023, 18, 754 & 2025, 20, 1237) and electrocatalytic hydrogen production (JACS 2025, 147, 16179 & 2025, 147, 2369; Energy Environ. Sci. 2024, 17, 3628; Adv. Mater. 2026, 17, e22703). Especially, we used machine-learning to discover champion oxygen evolution reaction electrocatalysts (Nat. Mater. 2024, 23, 108 & 2026, doi.org/10.1038/s41563-026-02622-6).
Professor Taeghwan Hyeon received B.S. (1987) & M.S. (1989) degrees from Seoul National University (SNU), and Ph.D. degree (1996) from UIUC, all in Chemistry Department. He is a SNU Distinguished Professor, and a Director of Center for Nanoparticle Research of Institute for Basic Science (IBS). He is recognized for his outstanding contributions in scalable synthesis of uniform-sized nanoparticles and related nanomaterials for energy & catalysis & medical applications. He was listed in Highly Cited Researcher (2014~25), and chosen as 2020 Citation Laureate in Chemistry. He received 2022 Grand Prize of National Academy of Engineering of Korea (NAEK), 2016 Presidential Best Scientist Award, 2012 Samsung Hoam Prize, and 2008 POSCO-T.J. Park Award. He is an elected Member of KAST&NAEK in Korea, US National Academy of Engineering (NAE), Royal Swedish Academy of Engineering Sciences (IVA), and Royal Society of Chemistry. From 2010 to 2020, he served as Associate Editor of JACS, and now of ACS Nano.
Clean water and clean air are vital for public health. This project focuses on developing high-efficiency and environmentally sustainable filters for removing harmful air/water pollutants. The team has developed novel architectures and functionalities for the filters to achieve high permeance, high removal efficiency, and excellent reusability.
