Manganese Dioxide Nanosheets Dispersion

Product Overview

Manganese Dioxide Nanosheets are two-dimensional nanomaterials with redox-active properties, consisting of three atomic layers: one Mn atomic layer and two O atomic layers. These nanosheets exhibit a broad absorption spectrum, with a particularly strong absorption at 380 nm, and possess a high molar extinction coefficient. The unique structure and properties of manganese dioxide nanosheets make them valuable in various fields, especially in energy storage, electrochemical catalysis, sensors, and biomedical applications.

Key Features

• Antioxidant Activity: Manganese dioxide nanosheets possess a strong free radical scavenging ability and exhibit enzyme-like activity, mimicking the functions of superoxide dismutase (SOD) and catalase (CAT), providing catalytic actions in oxidative stress mitigation.
• Electrochemical Performance: In the field of electrochemical energy storage, their high surface area and excellent conductivity significantly enhance charge/discharge speeds and increase energy density.
• Catalytic Performance: Manganese dioxide nanosheets offer highly active surfaces for oxygen-reduction reactions, hydrogen production via water electrolysis, and other catalytic processes, accelerating reaction rates.

Applications

• Energy Storage: Used as electrode materials in supercapacitors and lithium-ion batteries, they help increase energy density and improve charge/discharge rates.
• Catalysts: Employed in oxygen-reduction reactions, water splitting for hydrogen production, and other catalytic processes, enhancing reaction speed and efficiency.
• Biomedical: Used as a nanocarrier for DNA enzymes, enabling gene silencing therapies. They also serve in dual-modal imaging (fluorescence/NMR) to monitor their cellular delivery efficiency.
• Sensors: Due to their unique electronic properties, manganese dioxide nanosheets are ideal for chemical sensors, capable of detecting gases, biological molecules, and other target substances.
