In diesem Beitrag wird versucht, die katalytische Aktivitat von Ammoniakkatalysatoren verschiedener Zusammensetzung in Zusammenhang zu bringen mit ihrer inneren Oberflache, ihrem Porengefuge und ihrer Fahigkeit, Kohlenmonoxyd und Kohlendioxyd zu chemisorbieren. Die Wirkungsweise der Aktivatoren Al2O3, CaO, K2O und SiO2 wir diskutiert.read more

Alkali Doping in Heterogeneous Catalysis
TL;DR: It has been estimated that approximately 60% of all commercial chemicals are now obtained using processes involving heterogeneous catalysis as discussed by the authors, and over 90% of new large-scale plants employ heterogeneous catalysts.
Journal ArticleDOI
Surface characterization of ammonia synthesis catalysts
TL;DR: In this paper, the composition and topography of the surfaces of unreduced and reduced industrial ammonia synthesis catalysts (BASF S6-10) were investigated by means of scanning Auger electron spectroscopy.
Journal ArticleDOI
Alkali Metal Control over N–N Cleavage in Iron Complexes
TL;DR: The accumulated results indicate that cleaving the triple N–N bond to nitrides is facilitated by simultaneous approach of least three low-valent Fe atoms to a single molecule of N2, and suggest that the size of the alkali metal cation can control the number of Fe atoms that can approach N2.

Cobalt Molybdenum Bimetallic Nitride Catalysts for Ammonia Synthesis
KojimaRyoichi,AikaKen-ichi +1 more
TL;DR: In this article, C-promoted cobalt molybdenum bimetallic nitride (Co3Mo3N) was synthesized by nitridation of cobalt mixture with ammonia at 973K and was stable and more active for ammonia synthesis (15 mmol h−1g−1) at 673 K under 3.1 MPa (N2 + 3H2).
Journal ArticleDOI
Coordination chemistry insights into the role of alkali metal promoters in dinitrogen reduction.
TL;DR: This review discusses the literature on alkali metal cations as promoters for N2 reduction, in the context of the growing knowledge about cooperative interactions between N2, transition metals, and alkali metals in coordination compounds.

The cross-sectional areas of molecules adsorbed on solid surfaces
TL;DR: In this paper, the cross-sectional area of adsorbed molecules on solid surfaces for 23 different molecules has been assigned to the values derived from the Brunauer-Emmett-Teller theory of physical adsorption.
