Investigation of the performance of carbon quantum dots as pseudoenzymaticcatalase in inhibiting hydrogen peroxide in the body.

Rerecently,The enzyme catalase is the main regulator of hydrogen peroxide metabolism.Hydrogen peroxide in high concentrations is a toxic agent, while in low concentrations it performssome physiological processes such as signalling in cell proliferation, apoptosis, carbohydratemetabolism and platelet activationI [۱]. Synthetic enzymes with high stability and performancehave attracted the attention of many scientists [۲]. In this project, we prepared carbon quantumdots (CQDs) by the hydrothermal method and their activity as catalase enzyme in thedecomposition of hydrogen peroxide into water and oxygen was investigated. The activity of theCQDs was measured by UV-visible spectroscopy. The prepared Catalase were identified usingEDS, FT-IR, PL, TGA, CHN and UV-vis spectroscopy.As a result, the CQDs could be used assynthetic catalase enzyme to inhibit the action of hydrogen peroxide in body cells.
