Photocatalysis under visible light is a promising method for the removal of environmental pollution by solar energy. Nowadays, interest in metal oxides as photocatalysis is increasing. In the study, Ag@ZnO/TiO2 nanocomposite particles were synthesized using the hydrothermal method. Nanocomposite particles were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The photocatalytic effects of the synthesized samples on methylene blue, rhodamine B, and malachite green aqueous solutions under Xenon light were investigated. Photocatalytic degradation properties of the samples were evaluated by calculating the absorbance decreases in the UV–Vis absorption spectra (methylene blue 664 nm, rhodamine B 554 nm, malachite green 617 nm). It was observed that the photocatalytic effect of the zinc doped TiO2 composite sample in all applied dyestuffs was higher than in other samples. Furthermore, it was reported that zinc doped TiO2 nanocomposites had 99.85% degradation on methylene blue, 98.41% on the malachite green after 120 min, and 99.29% for rhodamine B at the end of 60 min.
