Abstract
The room temperature decomposition of N2O over prereduced Rh-based catalyst s (Rh supported on ceria, zirconia and titania-alumina) is studied as a fun ction of the oxygen content in the feed. Results indicate that Rh supported on titania-alumina shows lower degree of inhibition by gaseous oxygen on t his reaction, attributed to the role of the metal particle-support interfac e region in the reaction. The effect of Rh loading and of the reaction temp erature are consistent with the hypothesis.
