Professor Young-Woong Suh's research lab specializes in the development of advanced catalysts for sustainable energy applications, with a primary focus on liquid organic hydrogen carriers (LOHCs) and biofuel production. The lab investigates transition-metal and noble metal catalysts for hydrogenation and dehydrogenation reactions, emphasizing catalyst design for improved activity, selectivity, and stability. Key research directions include the optimization of support materials—such as mesoporous oxides and carbon-coated aluminas—and the engineering of nanoparticle morphology and surface properties to enhance performance in hydrogen storage and hydrodeoxygenation processes.

The liquid organic hydrogen carrier (LOHC) 2-(N-methylbenzyl)pyridine (MBP) shows good potential for H<sub>2</sub> storage based on reversible hydrogenation and dehydrogenation, with an H<sub>2</sub> storage density of 6.15 wt %. This material and the corresponding perhydro product (H<sub>12</sub> -MBP) are liquids at room temperature. Remarkably, H<sub>2</sub> release is much faster from H<sub>12</sub> -MBP over Pd/C than from the benchmark perhydro benzyltoluene over Pt/C at lower temperatures
Decalin is more easily dehydrogenated on Pt catalyst than Pd while the dehydrogenation of tetralin is more facile on Pd than Pt.
Catalyst stability in the hydrodeoxygenation of vegetable oils is one of the big challenges for practical production of bio-jet fuel. Particularly, supported Pt catalysts are known to show activity decay because of Pt sintering and coking. Herein, we report superior long-term stability of the Pt catalyst in the hydrodeoxygenation of palm oil by using the mesoporous γ-Al2O3 (MA) support synthesized by solvent-deficient precipitation (SDP). When the MA was prepared with a molar ratio of water to a
Transition-metal catalysts are essential to realize a liquid organic hydrogen carrier (LOHC) system based on reversible hydrogenation and dehydrogenation. To attain comparable hydrogenation activity to noble metal catalysts mainly used so far, catalyst constituents need to be blended together toward improved adsorption and kinetics. For nickel catalysis in the hydrogenation of aromatic LOHC (monobenzyltoluene), mesoporous SiO2–Al2O3 (MSA) supports are herein prepared by solvent-deficient precipi
Abstract The activity and stability of supported Pd catalysts are of crucial importance in the dehydrogenation of perhydro 2‐( n ‐methylbenzyl)pyridine (H 12 ‐MBP) reported as a potential liquid organic hydrogen carrier. Because of good stability examined in many hydroprocessing reactions, carbon‐coated alumina (CCA) was chosen as a support for Pd loading and prepared by the pyrolysis of glycerol solution with different concentrations. The catalytic activity and stability of Pd/CCA catalysts exh
Abstract Monobenzyl toluene (H 0 ‐MBT) is an interesting material as a liquid organic hydrogen carrier, which is commercially available as heat transfer oil. In H 2 storage of H 0 ‐MBT via the hydrogenation reaction, supported Ru catalysts were reported to show superior performance. Herein, ZrO 2 ‐supported Ru nanoparticles were synthesized by using triruthenium dodecarbonyl Ru 3 (CO) 12 as Ru precursor and precipitated zirconium hydroxide subjected to different ageing periods. Although the exte
5-Hydroxymethylfurfural (5-HMF), one of the most important platform molecules in biorefinery, can be directly obtained from a vast diversity of biomass materials. Owing to the reactive functional groups (-CHO and -CH<sub>2</sub> OH) in the structure, this versatile building block undertakes several transformations to provide a wealth of high value-added products. Among numerous well-established paradigms, the catalytic hydrogenation of 5-HMF towards 2,5-bis(hydroxymethyl)tetrahydrofuran (BHMTHF)
