Product Features

1.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.

2.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.

3.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.

4.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 of Nitrogen-doped reduced graphene oxide powder:

1.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.

2.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.

3.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.

4.Sensors: High sensitivity and excellent electrochemical performance make them ideal materials in the field of sensors, which can be used to detect gases, chemicals, and biomolecules in the environment.

5.Biomedical applications: have broad application prospects in the biomedical field, including biosensing, drug release, tissue engineering, and bioimaging.

Nitrogen-doped graphene oxide powder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
