According to a study from the United States, "The interaction between an active oxide and an oxide support plays a critical role in controlling the reactivity of oxide-on-oxide catalysts. In the present study; the reactivity of a small ceria cluster (Ce(sic)O4) supported on the reducible monoclinic zirconia and the irreducible gamma-alumina was investigated using the first-principles density functional theory method."
"that the binding energies of the Ce2O4 cluster on the supporting ZrO2(111) and gamma-Al2O3(100) substrates are -5.32 and -4.06 eV, respectively, indicating a very strong interaction. On the basis of these oxide-on-oxide model catalysts, the effects ...
