Low-content gold-ceria catalysts for the water–gas shift and preferential CO oxidation reactions
Low-content (<0.6 at.%) gold-ceria samples were prepared by one-pot synthesis by the urea gelation/co-precipitation method, and by sodium cyanide leaching of high-content (5 at.%) gold-ceria materials prepared by deposition–precipitation. These catalysts, containing cationic gold in ceria, are active for both the low-temperature water–gas shift (WGS) reaction and the preferential oxidation of C...
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 کاملSupport effect in high activity gold catalysts for CO oxidation.
In this work, we present a detailed study concerning the evaluation of the metal-support interaction in high activity gold catalysts for CO oxidation. Using the colloidal deposition method, model catalysts were prepared, which allow the isolation of the effect of the support on the catalytic activity. Prefabricated gold particles were thus deposited on different support materials. Since the dep...
متن کاملAu/CeO2 Catalysts: Structure and CO Oxidation Activity
In this comprehensive review, the main aspects of using Au/CeO2 catalysts in oxidation reactions are considered. The influence of the preparation methods and synthetic parameters, as well as the characteristics of the ceria support (presence of doping cations, oxygen vacancies concentration, surface area, redox properties, etc.) in the dispersion and chemical state of gold are revised. The prop...
متن کاملCompetition of CO and H2 for Active Oxygen Species during the Preferential CO Oxidation (PROX) on Au/TiO2 Catalysts
Aiming at an improved mechanistic understanding of the preferential oxidation of CO on supported Au catalysts, we have investigated the competition between CO and H2 for stable, active oxygen (Oact) species on a Au/TiO2 catalyst during the simultaneous exposure to CO and H2 with various CO/H2 ratios at 80 ̋C and 400 ̋C by quantitative temporal analysis of products (TAP) reactor measurements. It...
