The discussion is devoted to some controversial points related to the aromatization of paraffins at high temperature (around 500°C), and low hydrogen pressure (1–8 bar) over non-acidic catalysts, in particular platinum plus a second component on a

We have determined the surface composition of three different solid solutions (5 at.% Ni-Au, 4 at.% Pd-Au and 14 at.% Pt-Au) and two stoichiometric compounds (Ni 3 Sn and Pt 3 Sn), all of them selected because of their significance in current catalyt

Abrupt changes in the reaction ambient from 12 CO H 2 to 13 CO H 2 are utilized to obtain transientkinetic information regarding the causes of activity decline in the methanation over Raney nickel. From the responses we infer that the methanation pro

The interaction of O 2 , CO 2 , CO, C 2 H 4 and C 2 H 4 O with Ag(110) has been studied by low energy electron diffraction (LEED), temperature programmed desorption (TPD) and electron energy loss spectroscopy (EELS). For adsorbed oxygen the EELS and

An abrupt change in the reaction ambient from 12CO/H2 to 13CO/H2 leads to a gradual ingrowth of 13C in hydrocarbon chains. From the rate of 13C ingrowth we calculate C—C bonds to form on a time scale varying from ≤1 s (ruthenium) to ≥10s (cobal

An X-ray photoelectron spectroscopic study of the reducibility of Ptγ-Al2O3, Geγ-Al2O3, and Pt, Geγ-Al2O3 systems has shown that: (i) treatment with H2 at temperatures up to 650 °C leads to interaction between Pt and Ge, giving rise to the format

To assess the role of carbidic intermediates in hydrocarbon synthesis we have studied the incorporation of surface carbon into hydrocarbon products. To this end, supported transitionmetal catalysts (Ni, Co, and Ru) have been precovered with carbon, d

X-ray photoelectron spectra of the valence bands of NaCN, Li 4 Fe(CN) 6 , Li 3 Fe(CN) 6 , Ni(CN) 2 , Li 2 Pt(CN) 4 and LiSCN have been measured and interpreted. Normalization of the valence-band intensities by equalization of the nitrogen is intensit

Exchange of silicate anions into hydrotalcite-type materials leads to the ready formation of well-ordered two-dimensional silicate sheets. The combined evidence from diffraction, NMR, and IR allows for a global identification of the reaction product.
