Tungstated nano particles of zirconia supported on multi-walled carbon nanotubes (WOx-ZrO2/MWCNT) were synthesized by grafting an acetylacetonate precursor, Zr(acac)4 on MWCNT and impregnated with ammonium metatungstate. The Zr(acac)4 was thermally decomposed and crystallized to ZrO2 at 450°C and the impregnated ammonium metatungstate thermally decomposed at 450, 650 and 850°C. The catalysts were demonstrated to be hydrothermally stable and characterized by TEM, XRD, X-ray absorption, N2 adsorption and NOx-TPD. Catalytic activity was measured for cyclohexanol dehydration in liquid water.
Gary L. Haller is Research Professor of Chemical & Environmental Engineering, Yale University. He is also Director of Henry Koerner Center for Emeritus Faculty, Yale University and Visiting Fellow of Institute for Advanced Study, Technical University of Munich. He received his Ph.D. in Physical Chemistry from Northwestern University in 1966 and worked at Yale University from 1967. He is the international famous physical chemical and catalytic chemist, his main research field is in catalytic reaction process and reaction mechanism of basic research, by using spectroscopy to study the structure and surface activity of the catalyst, catalytic activity and selectivity, establishing situ spectroscopy methods of catalyst. For his prominent academic contribution in the field of catalytic chemistry, he has repeatedly won the various academic award of the United States and the international and as editor of Journal of Catalyst, the Catalysis Reviews-Science and Engineering, etc..
