M. Daturi et al., INFLUENCE OF THE ACTIVATION CONDITIONS ON THE ELIMINATION OF RESIDUALIMPURITIES ON CERIA-ZIRCONIA MIXED OXIDES, Journal de chimie physique et de physico-chimie biologique, 95(9), 1998, pp. 2048-2060
A series of samples belonging to the ceria-zirconia solid solution has
been investigated from the point of view of surface impurities, via T
PO/TPD and FTIR spectroscopy. Species likely due either to the precurs
ors or to atmospheric contamination have been taken into account and t
heir stability has been studied following two different thermal treatm
ents. A complete cleaning treatment is proposed in order to obtain pow
ders of satisfactory quality for catalytic purposes.
