In this research work, the degradation of Tartrazine pigment using a new nanocomposite of graphite nitride carbon with zinc oxide coated with zirconium particles has been investigated. First, graphite nitride carbon nanocomposite was synthesized with zinc oxide by co-precipitation method and then zirconium particles were decorated on g-C3N4@ZnO nanocomposite and its structure was examined using XRD, FT-IR, FE-SEM, SEM-Mapping, EDX, and DRS analysis. In the following, the photocatalytic activity of g-C3N4@ZnO-Zr in tartrazine degradation was studied. The influence of tartrazine concentration (10, 20 and 30 ppm), time of degradation and pH parameters on the photocatalytic properties of the nanocomposite was investigated. The results showed that tartrazine was degraded by more than 98% in 180 minutes in the presence of visible light and g-C3N4@ZnO-Zr photocatalyst under strong acid medium (pH=1). According to the obtained results, the increase of zirconium particles has a positive effect on the photocatalytic properties of g-C3N4@ZnO-Zr nanocomposite.
