Nd2O3-doped ZnO nanocomposites were obtained by the Pechini method. The influence of the alloying additive content on the microstructure, morphology, optical properties and photocatalytic activity of the powders were examined. The properties of the nanopowders were studied using X-ray phase analysis, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy. Only one phase is present in the X-ray diffraction patterns of the obtained ZnO powders doped with Nd2O3. According to SEM, the synthesized powders have a conglomerate structure. It was established that the morphology of powder particles primarily depends on the content of Nd3+ in the material. The photocatalytic properties of ZnO powders doped with neodymium oxide was investigated using methyl orange as a model pollutant. The obtained results indicate that the produced powders are potential candidates for practical application in the photocatalytic degradation of organic compounds.
