Abstract	Abstract Cd 0.5 Zn 0.5 S/ZnO composite photocatalysts were synthesized using the precipitation method and characterized by XRD, UV-vis DRS, PL and FE-SEM. Photocatalytic activities of the materials were evaluated by measuring the degradation of rhodamine B under visible light irradiation. Contrary to ZnO, Cd 0.5 Zn 0.5 S/ZnO materials absorb visible light as well as UV and their absorption intensities in visible region increased with increasing the Cd 0.5 Zn 0.5 S amount. The increment in the Cd 0.5 Zn 0.5 S con-tent in Cd 0.5 Zn 0.5 S/ZnO also leads to reducing the particle size and consequently increasing the specific surface area. Cd 0.5 Zn 0.5 S/ZnO materials with the larger Cd 0.5 Zn 0.5 S content showed the higher activity in the photocatalytic degradation of rhodamine B under visible light irradiation. Therefore, the heterojunction effect between Cd 0.5 Zn 0.5 S and ZnO as well as the adsorption capacity seems to give important contributions to the photocatalytic activity of the Cd
