Product Name
Name:Nitrogen-doped graphene sheet spherical mixture
Product Overview
N-doped graphene is a graphene material that introduces nitrogen atoms into the graphene lattice through a specific method, thereby altering its electronic structure and properties. The following is about nitrogen doping
Nitrogen atoms mainly exist in the amorphous carbon layer of graphene, replacing some of the positions of carbon atoms.
The doping concentration and position of nitrogen atoms have a significant impact on the electrical and optical properties of nitrogen doped graphene.
In theory, nitrogen doping can introduce additional n-type impurity energy levels, which theoretically reduces the p-type energy gap accordingly.
The interaction between adjacent nitrogen atoms can introduce π - π transitions and non covalent n - σ transitions, further modifying the electrical properties of the material.
Nitrogen doped graphene has high thermal stability, mechanical strength, and oxidation resistance.
After nitrogen doping, the new adsorption sites on the surface of graphene can synergistically interact with gases, liquids, or biomolecules, which has good application prospects.

Product Features
Good conductivity: Nitrogen doping can theoretically increase the carrier concentration and significantly improve the conductivity of graphene, which is better than carbon black. However, as it is a sheet-like material, the combination of compound and conductive carbon black can better form a conductive network, and adjusting the potential value can also improve the conductivity to some extent.
Excellent thermal conductivity: Nitrogen doped graphene has better thermal conductivity than graphite, and the effect of large and continuous phases is better, but other materials need to be added vertically to conduct heat.
Existence of active sites: The introduction of nitrogen atoms can generate more active sites in graphene, which is crucial for its application in chemical reactions, such as as as catalysts in fuel cells, with low cost, high catalytic activity, and good stability.
Adjustable electronic structure: The doping of nitrogen atoms changes the electronic structure of graphene, which helps to open the bandgap and thus alter its physical and chemical properties.
Application Fields
Electronic devices: Nitrogen doped graphene exhibits high carrier mobility and excellent conductivity in electronic devices, and can be used in field-effect transistors, flexible electronic devices, and sensors.
Energy storage: widely studied as an electrode material for lithium-ion batteries and supercapacitors, it has attracted much attention due to its high conductivity and excellent electrochemical performance.
Catalyst: Nitrogen doped graphene has abundant active sites and high specific surface area on its surface, making it suitable for use as a catalyst promoter, electrocatalyst, and photocatalytic reaction.
