Journal ArticleDOI
Catalytic activity and poisoning of specific sites on supported metal nanoparticles.
Swetlana Schauermann,Jens Hoffmann,Viktor Johánek,Jens Hartmann,Jörg Libuda,Hans-Joachim Freund +5 more
TL;DR: This work presents first direct evidence for the different activity of coexisting sites on a well-defined supportednanoparticle system and chooses the decomposition of methanol on well-ordered Pd crystallites as a model reaction.
Journal ArticleDOI
A molecular beam/surface spectroscopy apparatus for the study of reactions on complex model catalysts
TL;DR: In this paper, a newly developed ultrahigh vacuum (UHV) experiment which combines molecular beam techniques and in situ surface spectroscopy is described, specifically designed to study the reaction kinetics and dynamics on complex model catalysts.
Journal ArticleDOI
The CO oxidation kinetics on supported Pd model catalysts: A molecular beam/in situ time-resolved infrared reflection absorption spectroscopy study
Jörg Libuda,Ingo Meusel,Jens Hoffmann,Jens Hartmann,Laurent Piccolo,Claude Henry,Hans-Joachim Freund +6 more
TL;DR: In this article, the authors studied the kinetics of CO oxidation reaction on an alumina-supported Pd model catalyst and determined the steady-state CO2 production rate as a function of the CO fraction in the impinging gas flux.
Journal ArticleDOI
The interaction of oxygen with alumina-supported palladium particles.
Ingo Meusel,Jens Hoffmann,Jens Hartmann,Michael Heemeier,Marcus Bäumer,Jörg Libuda,Hans-Joachim Freund +6 more
TL;DR: In this paper, a combination of molecular beam techniques and scanning tunneling microscopy (STM) under ultrahigh vacuum (UHV) conditions was used to study the interaction of oxygen with an alumina-supported Pd model catalyst as well as the influence of the oxygen pretreatment on the kinetics of the CO oxidation reaction.
Journal ArticleDOI
An improved single crystal adsorption calorimeter for determining gas adsorption and reaction energies on complex model catalysts
Jan-Henrik Fischer-Wolfarth,Jens Hartmann,Jason A. Farmer,J. Manuel Flores-Camacho,Charles T. Campbell,Swetlana Schauermann,Hans-Joachim Freund +6 more
TL;DR: A novel vibrational isolation method for the pyroelectric detector is introduced for the reduction of acoustic noise and the absolute accuracy in energy is within ∼7%-9%.
