magnetic graphitic carbon nitride polymers: solvothermal synthesis as macroscopic samples (nano structure)

in order to prepare c3n4 as macroscopic sample, two synthesis attempts of the graphitic variety were carried out. the first consists on the condensation of melamine and cyanuric chloride (p d130 mpa, t d250±c) with triethylamine acting as solvent in supercritical conditions. the second one consists on the pyrolysis of melamine (p d2.5 gpa, t d800±c) in presence of hydrazine. the two routes led to a graphite-like carbon nitride; nevertheless, the first product is poorly crystallized and contains a larger amount of hydrogen as nhx due to a partial condensation .the sample was studied with uv/vis and ir and c nmr.
