Nowadays, over 90% H2 is still produced from steam reforming of natural gas. This process requires high temperature operation. Moreover, the natural gas is mostly provided from fossil fuel resources. In order to minimize the environmental impact, hydrogen produced from biomass resource has been a critical issue to the Department of Energy (DOE) in USA and abroad. The synthesis of functional nanomaterials offers a unique opportunity to make the breakthrough discoveries and truly revolutionary developments to meet these challenges. In this work, a series of Pt catalysts supported on transition metal oxide nanoparticles were prepared with different methods. These samples were characterized with Brunauer-Emmett-Teller (BET), chemisorption, temperature programmed reduction (TPR), temperature programmed desorption (TPD) and synchrotron-based X-ray diffraction (XRD) and X-ray absorption (XAS) techniques. The activity was tested with various bio-alcohols. The results have shown that the strong interaction between transition metal oxide nanoparticles and Pt nanoparticles increased the hydrogen production and lowered the reaction temperature significantly.



Dr. Xianqin Wang is an assistant 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. in early 2002. She was then a Post-Doctoral Fellow in Chemical Engineering Department at the North Carolina State University and stayed there for 9 months before joined the Chemistry Department in the Brookhaven National Laboratory (BNL) as a Research Associate in 2003. After working at BNL for two and half years, she moved to the Pacific Northwest National Laboratory (PNNL) in 2005, and remained there as a Scientist till she took the position at the NJIT. 

She has been awarded Outstanding Performance Award (OPA) at PNNL, 2007, Excellence Certificate from BNL, 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, session chair for national meeting.

Her research efforts have been focused on two major categories: developing advanced functional nanomaterials 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. The structural and catalytic properties of the fabricated materials were characterized with different kinds of advanced techniques including synchrotron-based in situ characterization techniques (TR-XRD, EXAFS and XANES), in situ FT-IR, GC, MS, solid state NMR, TPD, TPRS, and surface analysis techniques. She has published over 40 refereed papers including book chapter in both national and international journals and presented over 50 papers in the national and international conferences. (
