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
Supported Iron Nanoparticles as Catalysts for Sustainable Production of Lower Olefins
Hirsa M. Torres Galvis,Johannes H. Bitter,Chaitanya B. Khare,Matthijs Ruitenbeek,A. Iulian Dugulan,Krijn P. de Jong +5 more
TL;DR: A class of iron catalysts on relatively passive supports that robustly directed the FT process toward light olefins are demonstrated, using catalysts that constitute iron nanoparticles (promoted by sulfur plus sodium) homogeneously dispersed on weakly interactive α-alumina or carbon nanofiber supports.
Journal ArticleDOI
Generation, Characterization, and Impact of Mesopores in Zeolite Catalysts
TL;DR: In this paper, an overview is presented of the different approaches to generate and characterize mesopores in zeolite crystals and establish their impact on the catalytic action, and it is shown that electron tomography, a form of threedimensional transmission electron microscopy, is able to reveal the three-dimensional shape, size, and connectivity of the mesopore.
Journal ArticleDOI
On the origin of the cobalt particle size effects in Fischer-Tropsch catalysis.
J.P. den Breejen,P. B. Radstake,Gerrit Leendert Bezemer,Johannes H. Bitter,V. Frøseth,Anders Holmen,K.P. de Jong +6 more
TL;DR: The origin of the cobalt particle size effects in Fischer-Tropsch (FT) catalysis was studied and the surface-specific activity (TOF) quantitatively and the CH(4) selectivity qualitatively as a function of Co particle size for the FT reaction was studied.
Journal ArticleDOI
Electrocatalytic Activity and Stability of Nitrogen-Containing Carbon Nanotubes in the Oxygen Reduction Reaction
Shankhamala Kundu,Tharamani Chikka Nagaiah,Wei Xia,Yuemin Wang,Stefan Van Dommele,Johannes H. Bitter,M. Santa,Guido Grundmeier,Michael Bron,Wolfgang Schuhmann,Martin Muhler +10 more
TL;DR: In this paper, Nitrogen-containing carbon nanotubes (NCNTs) were prepared via pyrolysis of acetonitrile over cobalt catalysts at different temperatures to control the nitrogen content.
