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-C3N4. The bandgap has reduced to 2.70 eV by increasing the quantity of silver iodide in the nanocomposites. The photocatalytic activity of AgI/C3N4 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/C3N4 nanocomposites photocatalyst revealed better photocatalytic behavior than the genuine AgI and C3N4 which ascribed to synergic impacts at the interconnection of C3N4 and AgI. Furthermore, these nanocomposites have great potential for being a great antibacterial agent.

通过阳光和抗菌活性显着的光催化性能，可轻松制备碘化银/石墨化碳氮化物纳米复合材料。

通过室温下的超声辅助沉积和水热法成功地制备了碘化银/石墨化碳氮化物纳米复合材料。不同的质量比和制备过程会改变样品的结构，纯度，形状和规模。产物的纯度通过能量色散X射线光谱法（EDS）和X射线晶体学确认。样品的形貌和尺寸可以通过透射电子显微镜（TEM）和场发射扫描电子显微镜（FESEM）观察。对纯g-C3N4的带隙进行了评估，约为2.82 eV。通过增加纳米复合材料中碘化银的数量，带隙已降至2.70 eV。已经研究了AgI / C3N4的光催化活性，这是由于罗丹明B（RhB）和甲基橙（MO）通过合适的带隙通过可见光辐射而被破坏。制备的AgI / C3N4纳米复合光催化剂显示出比真正的AgI和C3N4更好的光催化行为，这归因于C3N4和AgI互连的协同作用。此外，这些纳米复合材料具有成为巨大抗菌剂的巨大潜力。
