Silver iodide/graphitic carbon nitride nanocomposites have been successfully fabricated through sonication-assisted deposition-precipitation route at room temperature and hydrothermal method. Varied mass ratios and preparation processes can modify the structure, purity, shape, and scale of specimens. The purity of the product was confirmed by Energy Dispersive X-Ray Spectroscopy (EDS) and X-ray crystallography. The morphology and size of specimens could be observed with transmission electron microscopy (TEM) and field emission scanning electron microscopy (FESEM). The bandgap was evaluated around 2.82 eV for pure g-CN. The bandgap has reduced to 2.70 eV by increasing the quantity of silver iodide in the nanocomposites. The photocatalytic activity of AgI/CN has been studied over the destruction of rhodamine B (RhB) and methyl orange (MO) through visible radiation due to their suitable bandgap. The as-prepared AgI/CN nanocomposites photocatalyst revealed better photocatalytic behavior than the genuine AgI and CN which ascribed to synergic impacts at the interconnection of CN and AgI. Furthermore, these nanocomposites have great potential for being a great antibacterial agent.
通过室温下的超声辅助沉积沉淀法和水热法成功制备了碘化银/石墨相氮化碳纳米复合材料。不同的质量比和制备工艺可以改变样品的结构、纯度、形状和尺寸。通过能谱（EDS）和X 射线晶体学确认了产物的纯度。通过透射电子显微镜（TEM）和场发射扫描电子显微镜（FESEM）可以观察到样品的形貌和尺寸。纯 g-CN 的能带隙约为 2.82eV。通过增加纳米复合材料中碘化银的数量，能带隙降低到 2.70eV。由于具有合适的能带隙，AgI/CN 纳米复合材料在可见光辐射下对罗丹明 B（RhB）和甲基橙（MO）的破坏进行了光催化活性研究。所制备的 AgI/CN 纳米复合材料光催化剂表现出比纯 AgI 和 CN 更好的光催化行为，这归因于 CN 和 AgI 之间的连接产生的协同影响。此外，这些纳米复合材料具有成为一种优秀的抗菌剂的巨大潜力。
