Welcome to Chemistry Lab for Nanocatalysts
We're inorganic chemistry research group at the Catholic University of Korea. We're particularly interested in layered double hydroxides (LDH) for Cosmetics, Fuel Cells, and Heterogeneous Catalysis.
Layered double hydroxide (LDH) is promising 2-dimensional materials for adsorption and stabilization of diverse molecules in their gallery space. The LDH nanosheet is qualified as ideal catalytic supports toward metal nanoparticles, as well as 2-dimensional building blocks for the construction of various functional materials.
Research
"Layered Inorganic Materials for Cosmetics, Fuel Cells, and Heterogeneous Catalysis"
Our group research interests cover a wide range of areas including novel approaches of transition metal LDH nanosheets for Fuel Cells catalysis and the synthesis of a hybrid system of LDH and metal nanoparticles for heterogeneous catalysis. We are also looking at the development of smart carrier systems with LDH and their applications in Cosmetics.

Smart Carrier for Cosmetics
Exposure to solar ultraviolet (UV) radiation and oxygen molecules can seriously reduce the chemical and biological activities of most cosmetic raw molecules. In order to protect these molecules against significant damages, it is essential to develop the diverse functionalization methods such as encapsulation by liposomes, immobilization in porous solid materials. We investigate the improvement of photo and thermal stability of several cosmetic compounds by incorporating them into the LDH. Especially, the inorganic layers of LDH can protect the incorporated active molecules against significant damages by UV and oxygen in the air.
Fuel Cells Catalysts
Fuel cells are considered the most promising sustainable energy technologies owing to high energy densities, high efficiencies, and negligible emissions of harmful gases. Transition-metal oxides such as Co3O4 have attracted significant attention as potential candidates for efficient ORR catalysts owing to their structural diversities and electrochemical stabilities. We investigate the green approaches for Mn-doped Co3O4 nanoparticles and their thin films. Recently we report a new synthesis of monodisperse Co3O4 nanocubes by using topo-chemical oxidation-reduction of Co(OH)2 nanosheets, which is ascribed to the active surface and the much lower oxidation potential of the exfoliated nanosheets of Co(OH)2.
Heterogeneous Catalysts
Gold nanoparticles embedded on solid supports have attracted interest as new heterogeneous catalysts for various organic reactions. To achieve enhanced catalytic activity, supporting materials are essential. They prevent aggregation of the gold nanoparticles during the catalytic process, enable easy separation from the reaction mixture, and thus improve reusability of the catalyst. The hydroxide groups and positive surface charges of LDHs provide strong binding affinity to negatively charged metal nanoparticles as well as some solid substrates without chemical modifications.

Professor
Professor Jong Hyeon Lee studied at Chemistry Department of Sungkyunkwan University, where he obtained his BSc in 2000, MSc in 2002, and Ph D. in 2005, under the direction of Professor Duk-Young Jung.
He was a visiting research fellow in the Chemistry department at the University of Oxford in 2007/08, where he worked in the group of Professor Dermot O’Hare on transition metal layered double hydroxide. He moved to SKKU as a senior researcher to study LDH applications and CuInGaSe inorganic solar cells in 2008/10.
From 2010 he was an assistant professor at the Catholic University of Korea, becoming a professor in 2021.
