For the first time, pure Tb₂MoO₆ nanostructures were successfully fabricated using Tb(NO₃)₃.6H₂O and (NH₄)₆Mo₇O₂₄.4H₂O as a precursor by ultrasonic method and characterized by via X-ray powder diffraction (XRD), Fourier-transformed infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), and Energy-dispersive X-ray spectroscopy (EDS). The various parameters such as the type of capping agent, ultrasonic time and power were optimized to achieve the appropriate sample. The results showed that the type of capping agent, ultrasonic time and power can influence on the morphology, size, and purity of the products, respectively. In this work, pure Tb₂MoO₆ nanostructures observed by PVP as capping agent in ultrasonic time and power of 30 min and 80 W, respectively. Optical property of optimized product was investigated via diffuse reflectance spectroscopy (DRS). The photo-catalytic activity of proposed nanostructure was studied in the presence of various dyes such as Methylene blue, methyl orange, and acid blue 92 as the water pollutants under UV light illumination. At 0.05 g of nanostructure, Methyl orange pollutant destruction was higher than the two other dyes.

首次使用Tb（NO ₃）₃ .6H ₂ O和（NH ₄）₆ Mo ₇ O ₂₄ .4H ₂成功地制造了纯的Tb ₂ MoO ₆纳米结构。O是通过超声方法制成的前体，并通过X射线粉末衍射（XRD），傅立叶变换红外光谱（FT-IR），扫描电子显微镜（SEM）和能量色散X射线光谱（EDS）进行表征。优化了各种参数，例如封端剂的类型，超声时间和功率，以获取合适的样品。结果表明，封端剂的类型，超声时间和功率会分别影响产品的形态，尺寸和纯度。在这项工作中，纯Tb ₂ MoO ₆PVP作为封端剂在30分钟的超声时间和80 W的功率中观察到的纳米结构。通过漫反射光谱法（DRS）研究了优化产品的光学性质。在紫外光照射下，作为水污染物的亚甲基蓝，甲基橙和酸性蓝92各种染料的存在下，研究了拟议的纳米结构的光催化活性。在0.05 g的纳米结构下，甲基橙污染物的破坏程度高于其他两种染料。
