This paper reports the synthesis, characterization and photocatalytic degradation of alizarin red S (ARS) on the novel new hetero-system ZnO-SnO2, The hetero-system, prepared by chemical route, was characterized by spectroscopy, energy dispersive spectroscopy (EDS) analysis, microscopy, diffuse reflectance and powder X-ray diffraction. Photo-degradation of ARSwas investigated on ZnO, SnO2 and ZnO– SnO2 hetero-system. The effect of catalysis dose, initial pH, initial concentration were investigated, the photocatalytic degradation was performed under sunlight irradiation, 84% of (20 mg/L) was degraded within 120 min for concentration. Batch kinetic experiments showed that the degradation follows a pseudo- first-order kinetic with a high correlation coefficient (0.994) according to the Langmuir- Hinshelwood model.
