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.
