Abstract
Pure ZnO, Sb-doped ZnO, and ZnO:Sb/g-C3N4 nanocomposite were prepared using a simple wet chemical route. The XRD results showed the hexagonal wurtzite structure of synthesized nanoparticles. The inclusion of Sb and Graphitic carbon nitride (g-C3N4) changes the lattice parameters without affecting crystal structure. From TEM images, the morphology of the ZnO:Sb/g-C3N4 nanoparticle was found to be agglomerated spherical nanoparticles which are embedded over the nanosheets of graphitic carbon. The P.L. studies of ZnO:Sb/g-C3N4 nanocomposite exhibit reduced luminous intensity due to increased charge transfer among the ZnO:Sb and g-C3N4which improved the photocatalytic activity. A decrease in the optical energy band gap of ZnO:Sb/g-C3N4 nanoparticles from 3.3 to 3.26 eV was analyzed by Diffuse reflectance spectroscopy. The photodegradation of Methylene Blue dye was studied in the presence of photocatalysts. The degradation efficiency and rate constant values for ZnO:Sb/g-C3N4 are 86% and 0.037 min−1for 60 min.
