Analysis of in situ EXAFS measurements on a 2.4 wt % Rh/A120, catalyst, reduced at 473 K after calcination at 623 K, shows the presence of two different rhodium-oxygen bonds (viz. 2.05 and 2.68 A). The oxygen neighbors of rhodium at a distance of 2.0

Autor: S. Khalid, R. Dujari, J. Shultz, J. R. Katzer, R. J. Emrich

Publikováno v: Review of Scientific Instruments. 53:22-33

A laboratory x‐ray absorption spectrometer is described which allows very high quality x‐ray absorption edge and extended x‐ray absorption fine structure (EXAFS) data to be obtained. The spectrometer utilizes a channel‐cut crystal configurati

Publikováno v: Catalysis Reviews. 20:155-208

During the last decade there has been increased interest in the production of synthetic fuels and chemicals feedstocks from coal and oil shale due to declining petroleum reserves. Table 1 gives the projected gasoline to mid-distillate ratio through t

AES study of oxidation of surface and bulk sulfides of Ni

Autor: J. R. Katzer, H. Windawi

Publikováno v: Journal of Vacuum Science and Technology. 16:497-502

The interaction of oxygen with sulfur‐covered nickel and nickel sulfide surfaces was investigated by AES. For the adsorbed sulfur the interaction appears to proceed via an intermediate step prior to the removal of sulfur; a proposed mechanism of in
