Abstract:

This research reported the preparation of the graphitic carbon nitride (g-C₃N₄) microspheres without template via microwave heating method using melamine as precursor. The as-synthesized samples were characterized by powder X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), field-emission scanning electron microscopy (FE-SEM), ultraviolet-visible (UV-Vis) and photoluminescence (PL). Results showed that the g-C₃N₄microspheres were successfully synthesized. The diameters of the microspheres range from 800 nm to 1.5 μm, and the shell thickness is about 50 nm. UV-Vis absorption edge and PL peak of the g-C₃N₄were shown at 457 nm and 468 nm, respectively, indicating the intrinsic semiconductor-like absorption in the blue region of the visible spectrum. This was the first attempt to prepare g-C₃N₄microspheres without template via microwave heating approach, which was proved to be facile and effective.
