Preparation of multilayer carbon microspheres by using graphitic carbon nitride as precursor

Multilayer carbon microspheres were synthesized by using graphitic Carbon Nitride as precursor. The result of SEM and TEM showed that micrometer-sized multilayer spherical carbon structure had been prepared without the designed addition of any catalyst or template. The composition of the sample indicated that the sample was pure carbon materials. The result of XRD and Raman revealed low graphitization degree of carbon microspheres. FTIR and the analysis of theoretical spectra calculated by using GAUSSIAN 03 program indicated carbon microspheres structure model consisted of many five-member carbon rings. It also can be the cause of the low graphitized degree.
