Highlights

Synthesized more then ten (10) novel aluminophosphates with 1-D chain, 2-D layer and 3-D open-framework structures.  Remarkable examples include AlPO-CJB1 ([Al12P13O52][(CH2)6N4H3]), the first aluminophosphate molecular sieve with Brönsted acidity, AlPO-CJ4, the first openframework aluminophsopahte with an Al:P ratio of ˝ which consists of propeller-like chiral motifs with both D and L configurations, and AlPO-CJ8, the first structural type of aluminophosphate chains with an Al/P ratio of unity.

Discovered some construction regularities for microporous aluminophosphates and predicted the coordination situation of Al and P atoms in the aluminophosphates with new Al/P ratio.

Involved in the developing of a simple and efficient computational method for design of zeolite frameworks with specified pore structures.  This method provides a novel and fast approach towards design of zeolite frameworks with desired pore structures.
      To the best of our knowledge, this constrained assembly of atoms approach provides, for the first time, an efficient way to design zeolite frameworks with specified pore structures.

Developed a brookite-supported gold catalytic system for CO oxidation which shows a significant enhancement of the gold catalysis stability against sintering compared to the more commonly used anatase support was prepared.  This work has been identified as very significant by referees of Chemical Communications and was selected as hot paper of Chemical Communications (Chem. Chem. 2004, 1918-1919).  “Papers published as hot paper have been rated as "very significant" and "in the top 10%" of papers published in Chemical Communications  by expert reviewers in the field.”, the editor of Chemical Communications said.

Prepared and systematically compared the Au catalysts supported on anatase, brookite, rutile, and P25 polymorphs of TiO2 for catalytic oxidation of CO.  The above mentioned work was reported by Chemical & Engineering News (C&EN, 2004, 82(39), 23-24) and was selected to be featured in the form of Highlight stories in the 2005 National Synchrotron Light Source (NSLS) Activity Report (http://www.nsls.bnl.gov/newsroom/science/2005/pdfs/2005-09-Dai.pdf).  Due to our excellent work in this topic, we are invited to write a chapter for the book of Nanotechnology in Catalysis and write a review article for Topics in Catalysis.

Developed a couple of ultra-stable Au nanocatalysis systems by combining the surface sol-gel technique and deposition-precipitation method.   The stability of the Au nanocatalysts we developed under high-temperature treatment in O2 is much better than that of the TiO2-supported Au reference nanocatalyst supplied by the World Gold Council as part of an initiative to promote the use of gold in this type of industrial use.  A patent related part of this work was recently filed.  The part of this work was also reported as highlight news by respected catalysis journal Applied Catalysis B: Environmental (Applied Catalysis B: Environmental, 2005, 60(3-4), N8) and quarterly published Oak Ridge National Laboratory Review (Oak Ridge National Laboratory Review, 2005, 38 (3), 21), which highlights research and development activities at ORNL, a multiprogram, multipurpose Department of Energy laboratory that conducts research in energy production and end-use technologies; biological and environmental science and technology; advanced materials synthesis, processing, and characterization; computing and computational sciences; and the physical sciences, including neutron-based science and technology.
