Carbon nitrides: A promising class of materials

Using a thermal decomposition process of an organic precursor (thiosemicarbazide) under an argon flow, a brown orange solid was prepared. Chemical analysis, X-ray diffraction and infrared spectroscopy characterizations reveal the formation of a well-crystallized bidimensional carbon nitride compound with a composition close to C3N4, Moreover, the availability of graphitic C3N4 in grain quantities, produced by low cost synthetic method, facilitates characterizations and further high pressure-high temperature phase transformations studies.
