One-step synthesis of highly efficient TiO2-CdS-Ag nanocomposite for remove organic pollution

•TiO2-NiS2-Ag nanocomposite was prepared by using microwave method.•Effect of microwave parameters on morphology of products were investigated.•TiO2-NiS2-Ag nanocomposite shows highly photocatalytic activity.•The photocatalytic activity and water treatment performance of the synthesized nanocomposite were studied. Here, a one-step synthesis of TiO2-CdS-Ag nanocomposite by microwave method was reported for the first time. Besides, the effects of preparation parameters such as reaction time and microwave power on the size, morphology and photocatalyst activity of TiO2-CdS-Ag nanocomposite were studied by SEM. Structure and composition of the obtained products were characterized by X-ray diffraction (XRD), scanning electronic microscopy (SEM), spectra energy dispersive analysis of X-ray (EDS) and ultraviolet–visible (UV–vis) techniques.
