摘要： Zirconium doped terbium nano oxides (ZrTb2O3). The nano oxides can have an average diameter ranging from about 17 nm to about 22 nm. The nano oxides can be used as a photocatalyst for photodegradation of organic dyes. In an embodiment, the organic dyes include textile wastewater dyes. In an embodiment, the textile wastewater dyes include methylene blue (MB) and/or Congo Red (CR). In an embodiment, the zirconium doped terbium nano oxides (ZrTb2O3) can be prepared by a dual co-precipitation and calcination method.
