In this study, TiO₂ nanostructured particles synthesized by hydrothermal method were characterized by X-ray diffraction and scanning electron microscopy. X-ray diffraction peaks of the samples were examined and rutile and anatase phases were observed. Morphological properties of the samples were examined in scanning electron microscopy images. These nanostructured particles were used in the application of degradation of waste water from dyestuffs. Methylene blue, melachite green and rhodamine b were used as dyestuffs, All samples were found to have high photocatalytic degradation. Particularly, it was observed that titanium dioxide nanostructured particles obtained by adding hexamethylene tetramine had a very high degradation of 94% and above on all dyestuffs.

本研究通过X射线衍射和扫描电子显微镜对水热法合成的TiO ₂纳米结构颗粒进行了表征。检查样品的 X 射线衍射峰并观察到金红石和锐钛矿相。在扫描电子显微镜图像中检查样品的形态学特性。这些纳米结构颗粒用于染料废水的降解应用。亚甲蓝、孔雀石绿和罗丹明b被用作染料，发现所有样品都具有高光催化降解。特别地，观察到通过添加六亚甲基四胺获得的二氧化钛纳米结构颗粒对所有染料具有94%及以上的非常高的降解。
