In the present work, conventional and sonochemical production of ternary reduced graphene oxide (rGO)-ZnO-TiO₂ nanocomposite photocatalyst was accomplished. XRD patterns of ternary nanocomposite indicated that it contained a combination of anatase and rutile phases of TiO₂ nanoparticles deposited over rGO sheet. TEM images revealed that ZnO and TiO₂ nanoparticles were evenly distributed on graphene sheet due to application of ultrasound. The photocatalytic degradation of crystal violet (CV) dye was performed to assess the photocatalytic activity of the sonochemically as well as conventionally prepared ternary nanocomposite. The beneficial effects of ultrasound were evident from the results as the nanocomposite synthesized using ultrasound assisted approach exhibited higher photocatalytic activity against the conventionally prepared nanocomposite.

在目前的工作中，完成了常规的和声化学的三元还原氧化石墨烯（rGO）-ZnO-TiO ₂纳米复合光催化剂的生产。三元纳米复合材料的XRD图谱表明，它包含锐钛矿相和金红石相的TiO ₂纳米颗粒沉积在rGO板上。TEM图像显示ZnO和TiO ₂由于超声的作用，纳米颗粒均匀地分布在石墨烯片上。进行了结晶紫（CV）染料的光催化降解，以评估声化学和常规制备的三元纳米复合材料的光催化活性。超声的有益效果从结果显而易见，因为使用超声辅助方法合成的纳米复合材料对常规制备的纳米复合材料表现出更高的光催化活性。
