(Texas A&M University. Libraries, 1993)The adsorption and oxidation of carbon monoxide were studied on model mono- and bimetallic catalysts of Pd(111), Pd(100), Cu(100), Rh(100) and Cu/Rh(100), using combined elevated pressure reactor/IR cell-UHV surface analysis ...
-
(2016-08-05)Ligand design has been an often pursued strategy to advance the development of transition metal complexes for catalysis and activation of small molecules. In the past decade, polydentate Z-type ligands have been recognized ...
-
(2014-07-29)Transition metal catalyzed cross-coupling reactions of aryl halides have revolutionized the synthesis of organic molecules. These reactions, which are commonly catalyzed by group 10 metals, have found applications including ...

The catalytic behaviors of lanthanum and neodymium oxides for dehydrogenation/dehydration of ethanol (Texas A&M University. Libraries, 1985)The ethanol dehydrogenation and dehydration reactions have been employed to investigate the nature and behavior of catalytically active sites on lanthanum and neodymium sesquioxides. In support of this objective, x-ray ...
-
(Texas A&M University. Libraries, 1979)The recent demands on the avialable energy have stimulated the search for alternatives to oil. Methanol, because of its abundance and the availability of technology to produce it from coal, is projected as an alternative ...
-
(Texas A&M University. Libraries, 1987)The results of this research indicate that [M⁺O⁻] centers (M = Group IA ions) in Group IA/Group IIA oxides are responsible for the catalytic production of CH₃[superscript dot] radicals from CH₄ through hydrogen atom ...
-
(Texas A&M University. Libraries, 1982)Alkali metal-graphite intercalates, NaC(,64), KC(,24) and KC(,8) and an iron-containing potassium-graphite (4.5 wt. % Fe) possess large adsorption capacities for carbon monoxide and exhibit high initial activities for CO ...
-
(Texas A&M University. Libraries, 1990)Ruthenium metal on a zeolite support was found to be active for the catalytic synthesis of ammonia from dihydrogen and dinitrogen at temperature between 300 and 450°C and at atmospheric pressure. A triply-promoted iron ...
-
(2014-10-31)One of the most pressing technical challenges in the production of biofuels from biomass is the unavailability of economical processes to remove 30-45% (w/w) of the oxygen that is present in biomass-derived oxygenates. The ...
-
(2019-03-21)No one can deny that the increasing energy demand -due to world population booming- and climate change are two major challenges facing humanity in the current century. Climate change phenomenon is basically related to green ...
-
(Texas A&M University. Libraries, 1983)A systematic investigation was made to correlate the electrocatalytic properties of perovskites, ABO(,3) (A is a lanthanide, B is a first row transition metal), for oxygen evolution with their electronic structures. The ...
-
(2014-11-07)The catalytic growth of single-walled carbon nanotubes (SWCNTs) is studied using reactive molecular dynamics (RMD) simulations and density functional theory (DFT) calculations. Computational calculations are performed in ...
-
(2014-10-31)Catalysis has enabled the development of very important industrial processes, especially those related to the petroleum and chemical industries. This has led to a significant influence in the worldwide economy, with 20% ...
-
(Texas A&M University. Libraries, 1991)Over La2O3 and the transition metal oxide catalysts LiNiO2 and NaMnO4/MgO it was demonstrated that the coupling of the surface-generated gas-phase Ch4 radicals constitutes a major pathway for the formation of C2+ hydrocarbons ...
-
(Texas A&M University. Libraries, 1986)In the past five years, the search for alternative sources of petrochemical feedstocks has turned attention toward non-conventional sources of chemical carbon other than carbon monoxide. A renewed interest in the chemistry ...
-
(2010-01-14)A molecular-level understanding of a heterogeneous catalytic reaction is the key goal of heterogeneous catalysis. A surface science approach enables the realization of this goal. However, the working conditions (ultrahigh ...
