Gold–ceria catalysts for low-temperature water-gas shift reaction
Nanostructured Au–ceria is a promising new catalyst for low-temperature water-gas shift (LTS). Preparation, characterization, and catalytic properties of this material are reported in this paper. Gold–ceria was prepared by deposition–precipitation (DP), coprecipitation (CP), and gelation methods. The gold loading was varied between 1 and 8.3 at.%, while lanthanum used as a dopant in ceria, was ...
متن کاملViability of Au/CeO2-ZnO/Al2O3 catalysts for pure hydrogen production via WGS
The production of H2 pure enough to use it in fuel cells requires the development of very efficient catalysts for the WGS reaction. In this study a series of gold catalysts supported on ZnO-promoted CeO2Al2O3 is presented as interesting systems for the purification of H2 streams via WGS. The addition of ZnO remarkably promotes the activity of a Au/CeO2/Al2O3 catalyst. This increase in activity ...

The composite system of nanostructured gold and cerium oxide, with a gold loading 5–8 wt%, is reported in this work as a very good catalyst for low-temperature water–gas shift. Activity depends largely on the presence of nanosized ceria particles. Various techniques of preparation of an active catalyst are disscussed. The presence of gold is crucial for activity below 300 ◦C. A dramatic effect ...
