This research reported the preparation of the graphitic carbon nitride （g-C3N4） microspheres without template via microwaveheating method us- ing melamine as precursor.The as-synthesized sam- ples were characterized by powder X-ray diffraction （XRD） , fourier transform infrared spectroscopy（FT-IR） , field-emission scanning electron mi- croscopy （FE-SEM） . Results showed that the g- C3N4 microspheres were successfully synthesized. The diameters of the microspheres range from 800 nm to 1.5μm, and the shell thickness is about 50 nm.
