Professor Chuang investigates the structure of adsorbed species and its reactivity by transient infrared (IR) techniques. These techniques combined with traditional characterization methods such as XRD, UV-Vis, NMR, SEM, and TEM have been used for studying the nature of adsorbed species and reaction pathways during oxygenate synthesis, hydroformylation, partial oxidation, reduction of nitric oxide, nitric oxide decomposition, oxidative carbonylation, photocatalytic oxidation and reduction, carbon dioxide adsorption, reactions on solid oxide fuel cell catalysts, and synthesis organic/inorganic hybrid materials. The objectives of his research program are (i) developing an understanding of the reactivity of adsorbed species and its associated sites, (ii) using mechanism information to guide catalyst and sorbent preparation, and (iii) scaling up of catalytic and adsorption processes from laboratory scale to the pilot scale.
