Graphitic carbon nitride (g-C₃N₄) has provoked wide research interests in heterogeneous catalysis and photocatalysis, owing to its special layered structure and related electronic properties. In this work, the g-C₃N₄ powder was treated by ultrasonic bath in both isopropanol (IPA) and IPA-H₂O solvents and then dispersed on various substrates including mica, HOPG and Au(111). With detailed atomic force microscopy (AFM) characterizations, It was found that after 10 hours of ultrasonic bathing, the g-C₃N₄ grains were exfoliated into planate particles as small as 100 nm and thin as 10 nm. However the expected g-C₃N₄ nanosheets were not formed. This is most likely due to the low crystallinity of the g-C₃N₄ powder produced by the thermal polymerization.
