Abstract

A quasi in situ X-ray absorption study demonstrated that the disproportionation of hydrogen peroxide (H₂O₂) promoted by ceria nanorods was associated with a reversible Ce³⁺/Ce⁴⁺ reaction and structural transformations in ceria. The direction of this reversible reaction was postulated to depend on the H2O2 concentration and the fraction of Ce³⁺ species in ceria nanorods.
