Abstract
Several phases with variable stoichiometry ZnxMn3−xO4(with x = 0.25, 0.85 and 1) and ZnOhave been obtained from the black mass, a widely generated residue of wasted alkaline bat-teries. The obtained samples have been characterized by X-ray diffraction (XRD) and Ramanspectroscopy showing results consistent with the stoichiometry obtained from chemicalanalysis. The study of the degradation of methylene blue (MB) and rhodamine B (RhB) underUV radiation demonstrates the photocatalytic behavior in all samples obtained, reachingdegradation percentages higher than 70% and 50%, respectively
