Su Cheun Oh, Ph.D.
Scientist
Polymer Science & Materials Chemistry
Hong Kong

Dr. Oh’s area of expertise is on material synthesis and catalytic science, with an emphasis on designing efficient catalysts for fuel conversions. She specializes in heterogeneous catalysis especially high-temperature gas-phase reactions and low-temperature liquid-phase reactions. She is very knowledgeable in material synthesis skills such as chemical formula development, chemical precipitation and co-precipitation, sol-gel, impregnation, electrochemical, high-energy ball-milling etc.

Dr. Oh has extensive expertise in various characterization tools including scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM), powder X-ray diffraction pattern (XRD), Brunauer–Emmett–Teller (BET), temperature programmed desorption (TPD) and chemisorption, thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS), infrared spectroscopy (IR) and Raman spectroscopy. She is also very well-trained in different chemical analysis skills, including gas chromatography (GC), high-performance liquid chromatography (HPLC) and mass spectroscopy.

Prior to joining Exponent, Dr. Oh was a research assistant in the Department of Chemical and Biomolecular Engineering at the University of Maryland, College Park. She developed novel catalyst systems to reduce the drawbacks in both oxidative coupling of methane (OCM) and direct non-oxidative methane conversion (DNMC) to increase the hydrocarbon yield from methane conversion. She precisely controlled the composition and morphology of hydroxyapatite (HAP) material to improve OCM catalytic performances. She also established reaction kinetics to explain the effects of these composition and morphology changes on OCM reaction. For DNMC reaction, she has developed a millisecond catalytic wall reactor made of metal oxide catalyst to enable high methane conversion, high C2+ selectivity, and long-term durability. In addition, Dr. Oh has also worked on biomass conversion using zeolite-based catalysts and studied membrane reactor systems to promote fossil fuel conversion efficiency.
