Photocatalyst (Eu–ZnO–Ag) was synthesized by precipitation-decomposition process. Thecharacterization catalyst by phase and size of catalyst by powder-XRD, morphology of catalyst by FE-SEM and optical properties by UV-visible and emission spectroscopy. The photocatalytic action of Eu–ZnO–Ag was investigated in the photodegradation of methylene blue dye in water under LEDs/ solar light. Eu–ZnO–Ag catalyst is indicating the excellent activity than Ag–ZnO, Eu–ZnO commercial ZnO/TiO2 nanoparticles. Co-dopants (Eu/Ag) shift the light absorbance of ZnO toward visible region. Factor affecting of photodegrdation study by dose, dye, solution pH on of methylene blue dye present solar/LEDs. The Eu–ZnO–Ag is established to be reusable photocatalyst. A potential photodegradation of methylene blue mechanism was discussed under illuminations LEDs/solar light.
