GdVO4:Eu3+ Nanocrystals as catalase mimics for hydrogen peroxide decomposition

Abstract

Hydrogen peroxide (H2O2) belongs to the family of reactive oxygen species and is vital for many redox metabolic reactions and cellular activities. It plays an important role in maintaining cellular homeostasis and influencing various physiological functions [1]. However, the reaction known as Fenton's reaction, which occurs between H2O2 and Fe2+ ions, is a significant contributor to the oxidation of biomolecules, resulting in the production of highly reactive hydroxyl radicals (•OH). This has led to increased interest in the development of preventive antioxidants that can interact with H2O2 without forming harmful radicals such as •OH
