Summary:[Display omitted] •ZnO and Mn doped ZnO nanoparticles are synthesized by using hydrothermal method.•Adsorption capacity and photocatalytic degradation of malachite green dye using ZnO and ZnO: Mn nanostructures as photocatalyst is verified.•Transition metal doping was varies the adsorption capacity of ZnO nanostructures since the presence of Mn affect the adsorption capacity (qt) of nanostructures.•Mn doped ZnO nanostructure shows higher photocatalytic activity of about 70% due to bandgap narrowing. The present study deals with the adsorption kinetics and photocatalytic dye degradation efficiency of hydrothermally synthesized Zinc Oxide (ZnO) and Manganese (Mn) doped ZnO nanostructures. The result shows that Mn doped ZnO possess higher photocatalytic activity than pure ZnO nanostructures for Malachite Green (MG) dye.
