The cubic crystalline structure is derived from XRD results and the existence of metal-oxide bond has been confirmed from FTIR studies. According to SEM and PSA analysis, the produced nanoparticles are found to be of nano size. The EDX data verified the presence of Gd, Zn, and O in the samples. Based on UV-visible spectroscopy, the band gap and λmax values were computed. In an aqueous medium and under UV light irradiation, the photodegradation of Rhodamine B over Zn doped Gd2O3 nanoparticles was studied. It was observed that Gd1.50Zn0.50O3-δ has exhibited 82% of photo-degradation of the dye solution which further increased to 96% because of increasing the catalyst loading. The effect of pH and the concentration of the dye are also reported. According to the kinetic analysis, the photocatalysis process followed a pseudo-first-order kinetic model. A radical scavenger technique was used to further examine and identify the function of photoactive species. Highlights Gd2-xZnxO3-δ (where x= where x=0, 0.1, 0.2, 0.3, 0.4 and 0.5) nanoparticles were prepared by simple one pot wet chemical precipitation method. Their physical characteristics were analyzed by XRD, FTIR, particle size analysis, SEM, EDAX, UV and PL studies. The photocatalytic degradation properties of Rhodamine B dye using                           Gd2-xZnxO3-δ based nanophotocatalysts were studied and reported. It was observed that Gd50Zn0.50O3-δ has shown 82% degradation efficiency of the dye solution which was further increased to 96% with increase in the catalyst loading. }, number={3}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Thaninki, Leena Vinolia and Nesaraj, Arputharaj Samson and Arunkumar, Manasai}, year={2023}, month={Dec.}, keywords={Zn doped Gd2O3 catalysts, Rhodamine B, Photodegradation, Co-precipitation method} }
