Research Interests

I am interested in analyzing crystal structures of both minerals and synthetic materials and understanding how the structures are related to their properties.  My research involves using in situ scattering and spectroscopic methods to study heterogeneous catalysts for chemical reactions related to hydrogen production, aiming at identifying active sites and species and elucidating reaction mechanisms. I am currently analyzing a group of Ni-based catalysts for ethanol steam reforming (ESR) reaction and attempting to improve activity and lifetime of the catalysts. A recent study on Ni/CeO2 catalyst revealed the how Ni metal and the ceria support interact in converting intermediate species involved in ESR. I am also working on synthesis of molybdenum carbide catalysts for carbon dioxide hydrogenation. I frequently use X-ray diffraction (XRD), X-ray absorption spectroscopy (XAS) and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) in my research.
