X-ray absorption study of ceria nanorods promoting the disproportionation of hydrogen peroxide

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.
