Crystallized nitrogen
WebNitrogen doping of carbon quantum dot results in improved fluorescence performance and a wider range of applications in photocatalysis, sensor and bioimaging, etc. Herein, a water-soluble and well-crystallized nitrogen-doped graphene quantum dot (N-GQD) has been obtained by using a MOF-derived carbon (ZIF-8C) as a new source of graphitic sheets. WebFeb 4, 2009 · In summary, through solvothermal reaction of C 3 N 3 Cl 3 and NaN 3 in CCl 4 at 180 °C for about 12 h, well-crystallized nitrogen-rich graphite-like carbon nitride has been successfully synthesized. TEM reveals the coexistence of spherical particles and crinkly lamellas at the nanometer scale in the samples prepared at the very mild conditions.
