Abstract:

Directing matter and energy now is to synthesize new forms of matter with tailored properties that will operate at the theoretical limits and will enable catalysts that are 100% specific and produce no unwanted byproducts. Fundamental understanding of the active sites and how to control the stability of the active sites are key to tackle the challenge. Low coordination defect sites on transition metals, such as steps and kinks, as well as open “rough” crystal faces that make low coordination metal sites available have been uniquely active for breaking H–H, C–H, C–C, C=O, O=O and N_N bonds. Oxide–metal interfaces provide highly active sites for reactions of C–H and C=O bonds. Thus the capability of controlling and tuning the properties of the transition metal or metal oxide in the catalysts determines whether we can address the main challenge. A fundamental understanding of structure-function relationships for catalysts is vital for the design of new catalytic materials. To accomplish this, new and efficient methods of in situ time-resolved characterization and rapid throughput testing of catalytic properties are crucial. In this talk, the functions of transition metal oxides in tackling the energy and environment challenges are reviewed. Their structure-function relationships in hydrogen production and biofuel upgrading will be discussed in detail.

Short Bio of Dr. Xianqin Wang：

Dr. Xianqin Wang is an associate professor in Chemical, Biological and Pharmaceutical Engineering Department at the New Jersey Institute of Technology (NJIT), where she joined in the fall of 2007. She obtained her Ph.D. in Chemical Engineering from the Virginia Tech. Her research efforts have been focused on two major categories: developing advanced functional nanomaterials for sustainable energy production and environmental protection, and investigating the structure and reactivity of catalytic systems under operation conditions including high pressure and temperature. She has successfully developed several different series of functional nanomaterials with various methods. She has published/submitted ~ 70 refereed papers including book chapters in both national and international journals with over 2000 citations (index>22) and presented over ~100 papers in the national and international conferences and invited seminar talks. She has been awarded Outstanding Performance Award (OPA) at PNNL in 2007, Excellence Certificate from BNL in 2004 and numerous scholarships and financial supports during her professional preparation. She has been actively taking part in the synergistic activities,

like proposal reviewer and journal reviewer and session chair for national meetings.
