abstract = {The surface chemistry of the Fischer-Tropsch catalytic
reaction over Co hasstill several unknows. Here, we report
an in-situ X-ray photoelectron spectro-scopy study of Co
0001$ð$ Þ and Co(1014), and in-situ high energy surface
X-raydiffraction of Co 0001$ð$ Þ, during the
Fischer-Tropsch reaction at 0.15 bar - 1 barand 406 K - 548
K in a H$_2$/CO gas mixture. We find that these Co
surfacesremain metallic under all conditions and that the
coverage of chemisorbedspecies ranges from 0.4–1.7
monolayers depending on pressure and tem-perature. The
adsorbates include CO on-top, C/-C$_x$H$_y$ and various
longerhydrocarbon molecules, indicating a rate-limiting
direct CO dissociationpathway and that only hydrocarbon
species participate in the chain growth.The accumulation of
hydrocarbon species points to the termination step
beingrate-limiting also. Furthermore, we demonstrate that
the intermediate surfacespecies are highly dynamic,
appearing and disappearing with time delays afterrapid
changes in the reactants’ composition.},
