(Texas A&M University. Libraries, 1982)The characterization of several molybdenum zeolites was facilitated using X-ray photoelectron spectroscopy. Samples prepared from the reaction of Mo(CO)(,6) with ultrastable zeolites exhibited superficially high concentrations ...
-
(Texas A&M University. Libraries, 1981)The decomposition of the {Ru(NH(,3))(,6)}('3+) complex in both X- and Y-type zeolites was investigated using several techniques including EPR spectroscopy, infrared spectroscopy, and Electron Spectroscopy for Chemical ...
-
(Texas A&M University. Libraries, 1989)A pulse-flow reaction system has been used to investigate the conversions of C₂-C₇ alkanes over SiO₂-,La₂O₃-, and charcoal-supported nickel catalysts. The effects of nickel loading level, reaction temperature, and structure ...
-
(Texas A&M University. Libraries, 1983)The active sites on La(,2)O(,3) that are responsible for 1-butene isomerization are "acid-base" pair sites which are generated by the thermal removal of surface hydroxyls over the pretreatment temperatue range 400(DEGREES)C ...
-
(Texas A&M University. Libraries, 1983)The nature of the active sites for ethane dehydrogenation over chromium supported on silica gel and the effect of the support on the properties of chromium catalysts for the dehydrogenation of ethane were investigated. Low ...
-
(Texas A&M University. Libraries, 1981)Lithium di-n-butyl(tri-n-butylphosphine)argentate(I) (2) and other organoargentate(I) complexes have been prepared and their mechanism of thermal decomposition studied. Chemical characterization of 2 by reaction first with ...
-
(Texas A&M University. Libraries, 1981)The formation of gas phase radicals during the partial oxidation of propylene, 1-butene, isobutylene, and methane over several metal oxides was investigated. The radicals were isolated by employing a matrix isolation unit ...
-
(Texas A&M University. Libraries, 1985)The formation of gas phase organic radicals during the reactions of methane, ethane, ethylene, propylene and toluene over a variety of metal oxides was investigated. Radicals were produced on the metal oxide surface in a ...
-
(Texas A&M University. Libraries, 1983)Insoluble polymers were shown to be capable of modifying catalyst activity when used as a support either for a transition metal catalyst or a ligand absorbing reagent. Polymer-bound Cp(,2)TiCl(,2) reduced by Grignard ...
-
(Texas A&M University. Libraries, 1982)The catalytic activity of metallic silver supported on zirconium phosphate has been examined in the reaction of ethylene oxidation in a flow reactor. The catalysts were prepared by ion-exchange of silver(I) ions in ...
