Journal ArticleDOI
Cobalt particle size effects in the fischer- : Tropsch reaction studied with carbon nanofiber supported catalysts
G. Leendert Bezemer,Johannes H. Bitter,H.P.C.E. Kuipers,Heiko Oosterbeek,Johannes E. Holewijn,Xiaoding Xu,Freek Kapteijn,A. Jos van Dillen,Krijn P. de Jong +8 more
TL;DR: X-ray absorption spectroscopy revealed that cobalt was metallic, even for small particle sizes, after the in situ reduction treatment, which is a prerequisite for catalytic operation and is difficult to achieve using traditional oxidic supports.
Journal ArticleDOI
A molecular beam study of the catalytic oxidation of CO on a Pt(111) surface
TL;DR: In this paper, the authors studied the reaction of carbon monoxide catalyzed by Pt(111) using reactive molecular beam-surface scattering and showed that at low coverage, the reaction proceeds with an activation energy E*LH =24.1 kcal/mole and a pre-exponential υ4 =0.11 cm2 particles−1
Journal ArticleDOI
A molecular beam study of the adsorption and desorption of oxygen from a Pt(111) surface
TL;DR: In this paper, the adsorption and desorption of O 2 on a Pt(111) surface have been studied using molecular beam/surface scattering techniques, in combination with AES and LEED for surface characterization.
Journal ArticleDOI
A molecular beam investigation of the interactions of CO with a Pt(111) surface
TL;DR: In this paper, the authors measured CO adsorbs on clean Pt(111) with an angular and temperature-independent sticking coefficient of 0.84 ± 0.05, where the coverage-dependence of the adsorption rate can be fitted by a precursor state model, where a weak adaption state for CO existing in the presence of pre-adsorbed CO plays the major role.
Journal ArticleDOI
Investigation of promoter effects of manganese oxide on carbon nanofiber-supported cobalt catalysts for Fischer–Tropsch synthesis
Gerrit Leendert Bezemer,P.B. Radstake,U. Falke,H. Oosterbeek,H.P.C.E. Kuipers,A.J. van Dillen,K.P. de Jong +6 more
TL;DR: In this article, the effects of the addition of MnO on a carbon nanofiber-supported cobalt catalyst were studied, and the results showed that MnO was associated with Co in both dried and reduced catalyst.
