Mechanism of ROS removal by CeO2 NPs (created with figdraw). Ce3+ on the surface transforms superoxide radicals into oxygen and H2O2, while Ce4+ scavenges H2O2 and generates oxygen and water, ultimately eliminating ROS. Due to the absorption of hydrogen electrons, Ce4+ is converted into the original Ce3+. The recyclable changes allow CeO2 NPs could be used as SOD mimetics and CAT mimetics as a logical therapeutic agents in treating ROS-induced inflammatory diseases
