Abstract In this study, Zinc Oxide and Silver and Copper-doped Zinc Oxide nanorods were synthesized by a simple template-free precipitation technique. In addition, meso-tetrakis (4-sulfonatophenyl) porphyrin (TPPS4) was prepared and immobilized on ZnO nanorods (TPPS/ZnO). The synthesized photocatalysts were characterized by various techniques such as X-Ray Powder Diffraction (XRD), Scanning Electron Microscopy (SEM), UV-visible Spectroscopy, Diffuse Reflectance Spectroscopy (DRS), and Fourier Transform Infrared Spectroscopy (FT-IR). The potential of the obtained photocatalysts in the degradation of methylene blue was investigated under UV and visible light irradiation. The results revealed that the photocatalytic activity of TPPS/ZnO was higher than those of the pure ZnO and doped ZnO under visible light irradiation.

Synergic Effect

CdS/Ag2S/g-C3N4 ternary composites showed excellent photocatalytic performance toward H2 evolution. Their improved photocatalytic activity could be attributed not only to the synergic effect, but also to the introduction of Ag2S.
