Nanosized TiO₂/ZrO₂=1:1 composites have been obtained by mechanochemical, ultrasonic, and coprecipitation methods. It is shown that mechanochemical and ultrasonic treatments of a TiO₂ and ZrO₂ mixture lead to size reduction of oxide particles, changes in X-ray diffraction spectra, the formation of a mesoporous structure of TiO₂/ZrO₂ samples, and an increase in their photocatalytic activity in the reaction of Gesagard (prometryn) herbicide destruction in an aqueous medium when compared to a mechanical TiO₂ and ZrO₂ mixture. It is found that the sample obtained by coprecipitation is X-ray amorphous with a well-developed surface, however, it is significantly inferior to samples obtained by alternative methods in terms of photoactivity.

纳米TiO ₂ /ZrO ₂ =1:1 复合材料已通过机械化学、超声和共沉淀方法获得。结果表明，TiO ₂和 ZrO ₂混合物的机械化学和超声处理导致氧化物颗粒尺寸减小，X 射线衍射光谱发生变化，TiO ₂ /ZrO ₂样品形成中孔结构，并增加与机械 TiO ₂和 ZrO ₂相比，它们在水介质中 Gesagard (prometryn) 除草剂破坏反应中的光催化活性混合物。发现通过共沉淀获得的样品是 X 射线无定形的，具有良好的表面，但是在光活性方面明显不如通过其他方法获得的样品。
