Abstract

Highlights

• Gd_2-xZn_xO_3-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                           Gd_2-xZn_xO_3-δ based nanophotocatalysts were studied and reported.
• It was observed that Gd₅₀Zn_0.50O_3-δ has shown 82% degradation efficiency of the dye solution which was further increased to 96% with increase in the catalyst loading.
