Equilibrium and Kinetics of NO and CO Chemisorptions on Nonstoichiometric Nickel-Copper Manganites.
The equilibrium and kinetics of adsorption of NO and CO on nonstoichiometric nickel-copper manganites have been investigated through volumetric measurements. The adsorption isotherms were satisfactorily fitted to the Freundlich equation. The equilibrium coverages at 298 K were found to depend closely on the chemical composition of the oxide; thus, a decrease in the coverage beyond a maximum cop...
متن کاملNew spinel materials for catalytic NO-CO reaction: nonstoichiometric nickel-copper manganites
Nonstoichiometric nickel–copper spinel manganites were found to be highly active for the reduction of nitric oxide by carbon monoxide at low temperature (300C). The activity increases with the level of nonstoichiometry of the oxides and almost linearly with their specific surface area. Moreover, this activity was found to depend strongly on the copper content, nickel manganites being almost ina...
متن کاملSurface Reaction Kinetics for Oxidation and Reforming of H2, CO, and CH4 over Nickel-based Catalysts
The catalytic conversion of hydrocarbons for the production of hydrogen and syngas (H2/CO) is of great interest in research and technology. Detailed heterogeneous kinetics can also provide a better understanding of the reactions involved during the catalytic processes commonly used in the synthesis gas production. The developed models can predict conversion and selectivity at varying operation ...
متن کاملAtomic-structural synergy for catalytic CO oxidation over palladium-nickel nanoalloys.
Alloying palladium (Pd) with other transition metals at the nanoscale has become an important pathway for preparation of low-cost, highly active and stable catalysts. However, the lack of understanding of how the alloying phase state, chemical composition and atomic-scale structure of the alloys at the nanoscale influence their catalytic activity impedes the rational design of Pd-nanoalloy cata...
متن کاملElectrocatalytic oxidation of formaldehyde on novel composite of nickel/triton-x100/poly(o-aminophenol-co-aniline)
Oxidation of formaldehyde (HCHO) is very important, owing to its use in fuel cells. Modification of electrodes surfaces is an excellent way to decrease the overpotentials as well as to increase the current density of the voltammetric response.pt as most efficient metal catalyst can easily be poisoned by product of oxidation and also it has high cost. In this work an efficient and low cost elect...
