N_2 Decomposition on Hydrotalcite Based Catalysts. A Mechanistic Approach

摘要

Catalysed N_2O decomposition has been studied on hydrotalcite like compounds. An important effect of the mixed oxide composition has been observed. Cobalt and, specially, rhodium, seem to have a decisive role in the catalytic activity of these samples. The reaction mechanism has been studied with the aid of the TEOM microbalance. The mass variation during reaction could be fitted to a model in which several adsorbed states of oxygen are considered.
