Prof. Ryoo Ryoo is a Distinguished Professor at KENTECH, which is an abbreviation for Korea Institute of Energy Technology.
He obtained a Ph.D. degree from Stanford University in 1986, under the supervision of Prof. Michel Boudart in the field of heterogeneous catalysis. After a one-year postdoctoral experience on solid-state NMR in the Prof. Alex Pines group at UC Berkeley in 1986, he worked for 35 years in the Department of Chemistry at KAIST. During 2012 ~ 2022, as a KAIST Distinguished Professor, he had a joint position at the Institute for Basic Science (IBS), where he directed the Center for Nanomaterials and Chemical Reactions. In March 2022, he moved to KENTECH Institute for Environmental and Climate Technology.
Research Overview
His main research field is nanoporous materials chemistry. Most remarkable achievements of his are the syntheses of mesoporous carbon materials called CMK-n (meaning Carbon Mesostructured at KAIST – No. n) and mesoporous zeolites.
The mesoporous carbons are built by regular arrangement of uniform mesopores. Due to the ordered arrangement of the controllable mesopore diameters, the CMK-n materials can be characterized by X-ray diffraction and electron microscopy.
This unique characteristic is a great advantage in nanoporous carbon science, where various physicochemical properties, such as electrocatalytic activity and adsorption ability, need to be explored as a function of the pore diameters and connectivity.
On the other hand, the mesoporous zeolite is a mesoporous material in which the mesopore walls are built with microporous crystalline zeolite framework. Compared to the solely microporous conventional zeolite, the mesoporous zeolite (also called zeolite with mesopore-micropore hierarchy, or hierarchical zeolite) has the advantage of facile diffusion of reactants and products.
This can lead to a significant increase in catalytic selectivity and lifetime when applied to petrochemical processes.
The mesoporous zeolite is expected to be a key component for the future development of advanced catalytic processes, in order to decrease pollutants generation and energy consumption.
