A novel two-step pathway towards sulphur-doped graphitic carbon nitride (CN) was hypothesized and practically tested. As a result of that, three new materials with the different content of sulphur (up to 0.023 wt.%) were synthesized. These materials were characterized by X-ray diffraction (XRD), X-ray fluorescence (XRFS), Fourier transform infrared (FTIR) and Raman spectroscopy and UV-Vis diffuse reflectance spectroscopy (DRS) all of which were compared with materials coming from procedures

Furthermore, photocatalytic properties of gained materials towards the decomposition of acid orange 7 (AO7) were tested and compared to known materials as well. All of three materials show less S-enrichment than CN (SCN) obtained by established procedures from thiourea, on the other hand, they bear a remarkable photocatalytic properties in photodegradation of AO7.
