This study presents the combining g-C₃N₄ nanosheet (NSCN) with Ag₂MoO₄ and AgI semiconductors through facile precipitation method as ternary visible-light-driven photocatalysts. The photoability of the nanocomposites was evaluated via photodegradation of different aqueous contaminants under visible-light excitation. The results displayed that the contents of Ag₂MoO₄ and AgI has considerable impact on photoability of ternary nanocomposite and the NSCN/Ag₂MoO₄/AgI (30%) nanocomposite illustrated best activity in the removal of MB, RhB, fuchsine, and MO, which was about 109, 155, 55.9, and 51.8-times premier than the bare CN, respectively. In addition, the boosted ability of the ternary system is 27.4, 22.6, 22.9, and 23.7 times superior relative to the NSCN in removal of MB, RhB, fuchsine, and MO pollutants, respectively, whereas the ability is 7.2, 4.9, 3.7, and 3.4 times premier than that of the NSCN/Ag₂MoO₄ (20%) system. The improved photoability was assigned to the enhanced absorption of visible light owing to the existence of small band gap semiconductors and improvement of the segregation of the charges due to the construction of ternary nanocomposite. The reactive species scavenging results predicted that superoxide anion radicals are the essential involved species in the RhB elimination. In addition, by evaluating the electrochemical features, a suitable mechanism was offered based on the band energies to explain the increased charges segregation and movement, which led to admirable photoactivities in removals of several hazardous pollutants.

这项研究提出了通过便捷的沉淀方法将gC ₃ N ₄纳米片（NSCN）与Ag ₂ MoO ₄和AgI半导体结合起来作为三元可见光驱动的光催化剂。通过在可见光激发下不同水性污染物的光降解来评估纳米复合材料的光敏性。结果表明，Ag ₂ MoO ₄和AgI的含量对三元纳米复合材料和NSCN / Ag ₂ MoO _4的光敏性有很大影响。/ AgI（30％）纳米复合材料显示了在去除MB，RhB，品红和MO方面的最佳活性，分别是裸CN的109倍，155倍，55.9倍和51.8倍。另外，三元系统的去除MB，RhB，品红和MO污染物的能力分别比NSCN高27.4、22.6、22.9和23.7倍，而去除能力分别为7.2、4.9、3.7和3.7。是NSCN / Ag ₂ MoO _4的3.4倍（20％）系统。由于存在小带隙半导体，并且由于三元纳米复合材料的构造，电荷的改善改善了可光性，这归因于对可见光的吸收增强。反应性物种清除结果预测超氧阴离子自由基是RhB消除中必不可少的参与物种。此外，通过评估电化学特性，基于能带能提供了一种合适的机制来解释增加的电荷偏析和移动，从而导致去除某些有害污染物时具有令人赞叹的光活性。
