Abstract:

The recent development of commercial software enables determination or prediction of catalytic activity. This has led to commercialization and potential commercialization of the TMS catalytic materials as described in reference 1. Additionally, we have developed a fundamental understanding of the catalytic materials as described in reference 2. This report will describe how the following interdisciplinary scheme has been applied to the TMS catalytic materials: Theory<=>Synthesis<=>Characterization<=>Application Shell Oil after WWII commercialized unsupported TMS catalytic materials but these were soon replaced for commercial reasons with the currently popular Al2O3 supported catalysts. In the 1970â??s researchers concluded, incorrectly, that the Al2O3 was fundamentally involved in the Promotion Effect. This effect today is understood in detail as the sharing of non-bonding d electrons in clusters that mimic noble metal for example Co9S8 + MoS2. This result we call Goldilocks, which will be discussed during the report. The model described in reference 2 is a detailed realization of the Contact Synergy described in reference 1. MoS2 interfaces with Co9S8 with a lattice fit at 1 1 1 crystal face. This creates at the interfaces a cubic lattice with the appropriate Co/Mo electron transfer allowing observed promotion. We will now discuss in detail the structure and meaning of Contact Synergy. Several papers are in preparation on this subject and will be discussed in detail.

Biography :

Russell R. Chianelli is currently Director of the Materials Research and Technology Institute at the University of Texas at El Paso and Professor of Chemistry, Materials and Environmental Science and Engineering. After receiving his PhD, he joined the Corporate Research Laboratories of Exxon Research and Engineering Co in 1974. While at this laboratory he conducted research in both fundamental and applied areas of interest to the energy industry. He is recognized worldwide for his work in Transition Metal Sulfide environmental catalytic materials. This work resulted in over 130 publications and 60 issued United States patents. During this period he was active in the Materials Research Society (MRS), serving as vice president (1989), president (1990), past president (1991) and Counselor (1992-1994). In 1996 he joined the Chemistry Department at the University of Texas at El Paso as Chairman and Professor of Chemistry and Environmental Sciences. In 2001 he resigned as Chemistry Department Chairman to head the Materials Research and Technology Institute (MRTI) at UTEP. The MRTI is dedicated to research relevant to the US/Mexico border in Materials related to energy, environment and health.
