Fischer-Tropsch synthesis on bimetallic ruthenium-gold catalysts
(Elsevier, 1985-06)
The effect of Au in the behavior of Ru as a Fischer-Tropsch catalyst was studied. Two series of catalysts were investigated, one supported on SiO2 and the other on MgO. Au did not seem to alter the product distribution on ...
Protein release from Escherichia coli cells permeabilized with guanidine–HCl and Triton X100
(Wiley Subscription Services, Inc., A Wiley Company, 1989-02-20)
An important factor complicating the recovery of recombinant proteins from Escherichia coli is their intracellular location. An alternative to the commonly used method of releasing these proteins by mechanical disruption ...
Molybdena on titania : I. Preparation and characterization by Raman and Fourier Transform Infrared spectroscopy
(Elsevier, 1985-04)
Titania-supported molybdenum and cobalt-molybdenum catalysts were prepared by the dry impregnation and equilibrium adsorption techniques. Raman and Fourier Transform Infrared spectroscopy were used to follow the changes ...
Electron microdiffraction study of bimetallic Ru---Au/MgO catalysts
(Elsevier, 1986-08)
A microdiffraction study of bimetallic Ru---Au/MgO catalysts is carried out in order to discriminate between the random adsorption versus atomic ordering model proposed for the structure of bimetallic clusters. The ...
The microstructure of bimetallic Ru---Cu/SiO2 catalysts: A chemisorption and analytical electron microscopy study
(Elsevier, 1986-08)
Supported bimetallic Ru---Cu/SiO2 catalysts are characterized by transmission electron microscopy, energy dispersive X-ray spectroscopy, electron microdiffraction, and chemisorption. Metal particles up to 4 nm in diameter ...
Bimetallic Ru-Au catalysts: Effect of the support
(Elsevier, 1981-06)
Ru-Au catalysts supported on SiO2 were characterized by using H2 and O2 chemisorption, wide-angle X-ray scattering, diffuse reflectance spectroscopy, and X-ray photoelectron spectroscopy. Catalytic activity was measured ...
Infrared spectroscopic study of NO reduction by H2 on supported gold catalysts
(Elsevier, 1986-11)
In situ Fourier transform infrared spectroscopy is used to study the reduction of NO by H2 on Au/SiO2 and Au/MgO catalysts. On these catalysts, large differences in selectivity toward N2 formation had been found depending ...
Influence of chlorine on the surface area and morphology of TiO2
(Elsevier, 1985)
Changes in BET surface area and morphology of TiO2 (anatase) were studied as a function of temperature and level of chlorine contamination. The obj
Solid state synthesis and characterization of model hydrodesulfurization catalysts
(Elsevier, 1989-10)
Solid-state reactions of elemental sulfur with metallic cobalt and molybdenum powders were used to synthesize model catalysts for hydrodesulfurization (HDS). The resulting materials had a general stoichiometry of Co2xMo1-xS2 ...
