TL;DR: In this article, the impregnation step can be explained in terms of interfacial coordination chemistry, and the choice of solvent, metal salt, and of the carrier is of great importance in the degree of reduction that can be achieved at normal reduction temperatures and catalyst dispersion.

TL;DR: A thermodynamic analysis on the simultaneous oxidation and re-reduction of small metallic cobalt crystallites in the presence of water and hydrogen as a function of the crystallite diameter was performed as a model for catalyst deactivation in the Fischer-Tropsch synthesis.

TL;DR: In this article, the Fischer-Tropsch synthesis of carbon nanotubes supported iron catalysts was performed using three different preparation methods: incipient wetness, deposition/precipitation using K 2 CO 3, and urea.

TL;DR: In this article, the authors proposed a new rate equation based on the assumption that the rate of the reaction in the Fischer-Tropsch synthesis is governed by the rate for hydrogenation of surface carbon, and this rate equation was used successfully to describe the kinetics of the consumption of carbon monoxide for the formation of organic compounds for both iron and cobalt based catalysts.

TL;DR: In this paper, the role of the external surface of TS-1 in the phenol hydroxylation was investigated by inertization of external surface, using cycles of lowtemperature chemical vapor deposition (CVD) of tetraethoxysilane followed by high-temperature calcination.
