In this paper, a turbostratic CN precursor was prepared by means of pyrolysis of melamine, then it was treated by high temperature and high pressure. The pyrolysis process of melamine, mechanism of hydrogen elimination and the effect of catalysts on pyrolysis of melamine were studied. The crystal structures, bonding states and chemical compositions of CN precursor obtained by pyrolyzing melamine are analyzed by X ray diffraction, burning spectrum, scanning elecron microscope and Fourier transform infrared Spectroscopy.

In this thesis, we concentrate on the development in theoretical prediction and experimental synthesis of CN compounds in the recent 10 years. By means of ion beam sputtering, treating melamine at high temperature and pressure, pyrolyzing melamine and treating pyrolysis products of melamine by impulsive discharge and high-speed impact, we explore the routes to synthesize carbon nitrides. The chemical compositions, crystal structures and bonding states of the CN films and powders obtained from the experiment are studied by the use of EDX, XRD, TEM, XPS and FTIR.

The results show that both of the "anaerobic" wastewater treatment and the sludge anaerobic digestion make the organic compounds in sludge so complicated that the organic compounds decomposition and release temperature becomes higher during pyrolyzing, and the "aerobic+anaerobic" process makes the organic compounds in sludge more complicated than the "anaerobic +aerobic" process. There is no influence on the combustion process and the burnout point, but can make the combustion temperature of sludge higher.
