Co/SiO 2 catalysts were prepared by aqueous cobalt nitrate impregnations of silicas with different surface areas to study the effect of the support surface area on the reactions occurring during impregnation and calcination and to define the stage an

Co/SiO 2 catalysts were prepared by both impregnation and precipitation techniques and analyzed by IR, TPR, XRD, and BET methods at intermediate stages of their preparation to define the stage and mechanism of cobalt silicate formation. To prove that

Adding Fe to Pt/SiO2 catalysts improves activity for methanol synthesis from 3H2/CO at 523 K and 3.19 MPa. Over 90% methanol selectivity can be achieved at low conversion, depending on the metal composition and dispersion.In situ Mossbauer measuremen

It has been more than ten years since the discovery of highly active catalysts which allow low temperature (< 150°C), single pass conversion of syngas to methanol. Detailed studies including catalyst refinements, reactor engineering, and process dev

The surface magneto-optic Kerr effect (SMOKE) technique was used to search for ferromagnetism in monolayer-range films of Cr and Fe grown on Au(100) and Cu(100). The growth modes were characterized using low energy electron diffraction (LEED) and Aug

We have used photoemission spectroscopy with synchrotron radiation in the energy range hν=40–140 eV to study the interface formation of Ag overlayers on cubic SiC(100). Our data are consistent with a three‐dimensional island growth mode of Ag at

We present an angle resolved synchrotron radiation photoemission study in the photon energy range hν=40–140 eV of the Sn/SiC(100) interface formation. Valence‐band and core level photoemission spectra suggest that the first monolayer of Sn grows
