The nano-particle rare-earth substituted copper ferrites CuRExFe2-xO4 (where, RE = Nd, Sm and Ho and x = 0.1 and 0.2) have been synthesized by tartarate co-precipitation method. The preparation processes were monitored by thermal studies and FTIR. The thermal decomposition studies of the precursor’s show that all the complexes dehydrate and decompose in the temperature range 30 to 600oC to produce nearly nanometer sized ferrite materials. The bi-dentate linkage of tartarate group with metal was confirmed on the basis of the difference between the anti-symmetric and symmetric starching IR frequencies. The ferrite samples are characterized by chemical analysis, XRD, FTIR, SEM-EDAX and UV-DRS methods. X-ray diffraction analysis reveals the formation of cubic spinel structure in all the ferrites samples. Morphology of the samples was investigated by a SEM. Rare-earth substituted CuFe2O4 samples exhibit the average crystallite size of all ferrites powders ranges from 26.2 nm to 38.4 nm. The photo-catalytic activity of all the nano-ferrites was evaluated by the degradation of methylene blue (MB) dye and it was observed that the degradation of MB dye takes place at pH-10. Among the all doped copper ferrite best photo-catalytic activity towards the degradation of MB
