Simple synthesis and characterization of Ag2CdI4/AgI nanocomposite as an effective photocatalyst by co-precipitation method

In present study, silver cadmium tetraiodide/silver iodide (Ag2CdI4/AgI) nanocomposites have been synthesized successfully by simple co-precipitation method. The effect of Ag+ molar ratio to Cd+ 2 and type of capping agent on morphology, size and purity of products was investigated. The obtained products were characterized by X-ray diffraction (XRD), field emission scanning and transmittance electron microscopy (FESEM, TEM), Raman and X-ray energy dispersive spectroscopy (EDS) analysis. The optical property of this product was studied by Ultraviolet-visible spectroscopy (UV-vis) and its band gap was estimated about 2.8 eV. Application of this product as photocatalyst through degradation of methyl orange (MO) under UV irradiation was investigated and degradation percentage of MO about 96.6% after 100 min was calculated.
