Nitrogen Doped Graphene Description
Graphene is a new material with a monoatomic layer sheet structure composed of carbon atoms. It has excellent light transmittance and thermal conductivity. It is the thinnest, hardest, and least resistive material known.
Nitrogen-doped graphene (N-graphene) is obtained by exposing graphene to nitrogen plasma. N-graphene exhibits much higher electrocatalytic activity toward oxygen reduction and H2O2 reduction than graphene, and much higher durability and selectivity than the widely-used expensive Pt for oxygen reduction. The excellent electrochemical performance of N-graphene is attributed to nitrogen functional groups and the specific properties of graphene.

Nitrogen Doped Graphene Applications
1. Electrocatalysis: Nitrogen doping enhances graphene’s catalytic activity, making it a promising alternative to precious metal catalysts (like platinum) in fuel cells, metal-air batteries, and other energy conversion applications.
2. Energy Storage: NDG is used in lithium-ion, sodium-ion, and supercapacitor electrodes. The nitrogen atoms improve the material’s conductivity and energy storage capacity, contributing to faster charge/discharge rates and higher energy densities.
3. Sensors: Nitrogen-doped graphene is highly sensitive to various molecules, making it useful in gas and biosensors for detecting environmental pollutants, gases, or biological markers in medical diagnostics.
4. Photocatalysis: NDG has shown promise in photocatalytic applications, such as water splitting and CO₂ reduction, due to its enhanced light absorption and electron transfer properties, driven by nitrogen doping.
5. Biomedical Applications: In drug delivery and bioimaging, NDG's biocompatibility and surface functionality allow it to interact with biomolecules, making it useful for targeted drug delivery and biosensing applications.
6. Supercapacitors: NDG is used to create electrodes with higher surface area and conductivity for supercapacitors, enhancing energy storage capabilities and performance in power electronics.
7. Anti-Corrosion Coatings: The material can be applied as a coating to protect metals and other materials from corrosion, utilizing its chemical stability and protective surface properties.
8. Water Purification: Due to its enhanced adsorption properties, NDG can be used to remove heavy metals, organic pollutants, and other contaminants from water in filtration systems.
9. Solar Cells: NDG’s improved charge transfer and light absorption make it valuable in dye-sensitized and other types of solar cells, potentially boosting efficiency and stability.
