Large-scale synthesis of nitrogen-rich carbon nitride microfibers by using graphitic carbon nitride as precursor

One-dimensional structures of nitrogen-rich carbon nitride are synthesized via a thermal evaporation process. The C-N atomic rings (s-triazine and/or tri-s-triazine) present in the precursor remain stable during the thermal evaporation and vapor transfer. They act as basic building blocks during the microstructure assembly; thus ensuring a high nitrogen content in the final product.
