Catalase-like hydrogen peroxide decomposition by GdVO4 :Eu3+ nanocrystals

Abstract

Hydrogen peroxide (H2O2) is a member of the reactive oxygen species family and plays a critical role in numerous redox metabolism reactions and cellular processes. It is considered a key component in the homeostatic metabolism of cells, mediating various physiological processes. However, the Fenton reaction between H2 O2 and Fe2+ ions is a major cause of biomolecule oxidation reactions, leading to the formation of highly reactive hydroxyl radicals (•OH). Therefore, there is significant interest in preventive antioxidants that can react with H2O2 without generating free radicals like •OH
