What is Graphitic Carbon Nitride?
Graphitic Carbon Nitride
Graphitic Carbon Nitride (g-C3N4) is a layered carbon-nitride material for Catalysis, Energy Storage, and Carbon Dispersion, available as powder or dispersion with grade-dependent particle, sheet, surface-area, and colloidal-stability characteristics.

What It Is Not
- Graphitic Carbon Nitride is not graphite and is not a conventional carbon nitride ceramic; it is the layered g-C3N4 material family.
When Not to Use It
- Do not use Graphitic Carbon Nitride when the target reaction, electrode mechanism, or dispersion medium has not been validated.
Intrinsic Screening Summary
- Identity screen
- Graphitic carbon nitride; Yellow to yellowish-brown layered powder; ultrathin nanosheet dispersions are available
- Intrinsic feature
- The (100) and (002) XRD reflections assess the layered structure; UV-Vis/Tauc testing assesses the typical 2.6-2.85 eV optical band-gap range.
- Material-level integration
- Select powder or dispersion form by the required particle or lateral-sheet size, BET surface area, medium compatibility, solid content, pH, zeta potential, and settling tolerance. Confirm the selected grade using lot-specific test data before release.
