Homoexchange reaction

O/ O homoexchange reaction (or equilibration reaction) on supported metal catalysts. In fact. Of O homoexchange is an overall measurement of the adsorption/desoiption rate. Recent results from our Group are presented hereafter. 

As a result, two types of reactions may be studied homoexchange and heteroexchange and two different levels of information are accessed. 

In most cases, this reaction is much more rapid on the metal than on the support. Those metals which cannot catalyse equilibration are poor X donors for exchange with the support. In what follows, we will consider the case where homoexchange occurs at a significant rate only on the metal. 

The mechanisms of homoexchange are similar to those of heteroexchange, where the atoms of the solid in the latter case are being replaced by-adsorbed atoms in homoexchange. Three mechanisms can occur according to the number of these adsorbed atoms involved in the reaction zero, one or two atoms.
