ZnO / Cu2+nanoparticles were synthesized by sol gel method on granular porous natural scoria. Structure andmorphology of Cu2+/ZnO/Scoria nanocomposites were studied by X-ray diffraction and scanning electron microscopy.Particles of ZnO/Cu2+ on scoria by these analyzes were obtained mostly 70nm. Photocatalytic performance ofnanocomposites was examined for Acid Blue 113 removal from aqueous solution in a continuous open channel reactorunder visible irradiation. Acid Blue 113 decolorization was obtained 70.78%. Results reveal that Cu2+/ZnO/scoriananocomposite acts as a good photocatalyst in continues reactors under visible light.
