N2 - The push to find new catalytic materials has intensified due to environmental concerns and the pressing issue of dye breakdown. In our research, we delve into the properties of ZrO2-doped LiTa0.5Nb0.5O3, a material made using a solid-state method. We extensively studied its structure, appearance, optical properties, dielectric areas, and surface conditions. Notably, Zr 5% composition exhibited an efficiently breaking down Rhodamine B (RhB) under simulated UV sunlight. In just an hour, it achieved a remarkable 98.2% degradation rate. This superior performance stems from active complexes forming on its surface and its impressive light absorption. Moreover, the degradation of RhB by this catalyst is boosted by the presence of reactive •O2¯ species generated during the process. Even after five rounds of testing, the catalyst retained an 81% efficiency rate. These results indicate the potential for creating efficient catalysts that can swiftly neutralize harmful dyes from water. Graphical Abstract: (Figure presented.)
