Inhibition of Adrenaline Autooxidation by Nanocrystalline Ceria

摘要

Nanocrystalline ceria CeO-(2-x) is a promising antioxidant [1]. Interest in this compound has especially increased after the discovery of its ability to inactivate reactive superoxide radicals [2], like superoxide dis-mutase (SOD). This process is driven by considerable oxygen nonstoichiometry of nanoceria [3-5] and the coexistence of Ce~(3+) and Ce~(4+) ions on the surface of CeO_(2-x) nanoparticles (reaction (1)).
