A simple precipitation-decomposition method to prepared (Co and Ni-doped ZnO Nps) photocatalyst. The photocatalyst were characterized by various techniques such as Power-XRD, TEM, SEM and Optical spectra. The influence of dopants (Co/Ni) content on the optical properties was investigated. It has been found that the (Co/Ni) doping leads to the optical band gap reduction. Pure and (Co/Ni) doped ZnO nanoparticles possess improved photocatalytic activity and stability and reusability of catalyst are promising for potential performance in degradation of methylene blue dye under solar light irradiation.
