Nitrogen-doped graphene oxide, high purity n-type semiconductor

High quality 2D material and expert support available online


Nitrogen-doped graphene oxide (much like graphene oxide) is easily dispersed within solution, which allows it to be processed in high concentrations. Unlike standard graphene oxide, the doping with nitrogen transforms the material from a p-type material to an n-type material. By transforming the material into an n-type semiconductor, graphene oxide can be used in a wider variety of electronic device structures. In addition, nitrogen-doped graphene oxide can be used as a precursor for the formation of nitrogen-doped graphene.

Ossila currently stocks nitrogen-doped graphene oxide in a single flake size of 1-5μm.

What is Nitrogen-Doped Graphene Oxide?


N-doped graphene oxide (NGO) overcomes the disadvantages of graphene oxide (GO) by adding nitrogen doping into the process of GO synthesis to repair defects and improve the electronic structure of GO.

The introduction of the nitrogen group will not only modify the functionalities of graphene oxide, but it will also change the chemical, optical and electronic properties by substituting the oxygen groups with nitrogen groups in the graphene lattice. Firstly, with more functional groups embedded to the graphene structure, n-doped graphene oxide is more chemically active than graphene oxide. Secondly, replacing oxygen functional groups on graphene oxide sheets with nitrogen-containing groups transforms GO from a p-type into an n-type semiconductor. This can promote hole transport for certain applications, improvement of biocompatibility of carbon devices in biosensing, and enhancement of the performance of graphene-based supercapacitors.

N-doped graphene oxide (NGO) is also an intermediate for the synthesis of N-doped graphene/reduced graphene.

Dispersion Guide

Much like graphene oxide, nitrogen-doped graphene oxide has a high dispersibility; this allows for high concentrations. This can be done in a variety of polar solvents. At Ossila we have found that the most stable solutions can be produced using the following recipe:

  • Weigh out desired amount of material, this can go up to at least 0.5 mg.ml-1.
  • Add 1:1 ratio of deionized water to isopropyl alcohol.
  • Shake vigorously to break up material.
  • A short treatment in an ultrasonic bath will rapidly disperse the material.
