chemical nanoparticle ceric oxide ceric oxide nanoparticle 2026-01-08T15:55:24Z CeO2 nanoparticle This is any condition in which the main influencing factor is a particle with a size between 1 and 100 nanometers composed of ceric oxide (CeO2). These particles can switch between Ce3+ and Ce4+ oxidation states, giving them catalytic, self-regenerating free radical-scavenging activity.
