Journal ArticleDOI
Surface and bulk properties of Cu–ZSM-5 and Cu/Al2O3 solids during redox treatments. Correlation with the selective reduction of nitric oxide by hydrocarbons
TL;DR: In this article, the redox properties of Cu ions implanted in ZSM-5 and supported on Al2O3, catalysts active in the selective reduction of NO by hydrocarbons such as propane, are investigated.
Journal ArticleDOI
Deactivation of nickel-based catalysts during CO methanation and disproportionation
TL;DR: In this paper, the complex process of deactivation of Ni-based catalysts during CO methanation and disproportionation is studied by means of coupled kinetic and in situ physical methods (magnetism and infrared spectroscopy).
Journal ArticleDOI
Catalytic combustion of methane over palladium supported on alumina and silica in presence of hydrogen sulfide
TL;DR: In the case of the silica support infrared spectroscopy shows that the poisoning species would be a sulfate group bonded to the palladium surface atoms as mentioned in this paper, and this technique allows to determine the variations of the amount of sulfur deposited after poisoning and after thermal treatment.
Journal ArticleDOI
Preparation and characterisation of high surface area stannic oxides: structural, textural and semiconducting properties
Nicolas Sergent,Nicolas Sergent,Patrick Gélin,Laurent Périer-Camby,Hélène Praliaud,Gérard Thomas +5 more
TL;DR: In this article, two different methods, nitric acid attack on metallic tin and neutralisation of SnCl4 solution by hydrazine, were used to extract cassiterite-type samples and their evolution as a function of the temperature of calcination in flowing oxygen up to 600°C has been studied.
Journal ArticleDOI
Role of the Nature of the Support (Alumina or Silica), of the Support Porosity, and of the Pt Dispersion in the Selective Reduction of NO by C3H6 under Lean-Burn Conditions
TL;DR: In this article, the influence of various parameters over a large range of initial metal dispersion was examined, including the nature of the support (silica or alumina), support porosity, presence of impurities (particularly chlorine or sulfur), and the Pt particle size distribution.
