Abstract: g-C3N4/Ag/TiO2 ternary photocatalysts were successfully constructed by a mechanical agitation method with as-synthesized Ag/TiO2 hollow microspheres and g-C3N4 nanosheets as the raw materials. The photocatalysts were systematically characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS), and photoluminescence spectra (PL). The results showed that g-C3N4/Ag/TiO2 was assembled by Ag/TiO2 microspheres and g-C3N4 nanosheets. Compared with TiO2, the resultant g-C3N4/Ag/TiO2 heterojunctions possessed longer visible-light response range and faster photo-induced carrier separation rate. At room temperature, the visible-light photocatalytic activity of g-C3N4/Ag/TiO2 was investigated by photodegradation of rhodamine B (RhB). The results showed that the highest visible-light-driven photocatalytic efficiency of g-C3N4 (0.5%)/Ag/TiO2 with 180 min of light irradiation was 91.9%, which was nearly 7.5 and 1.8 times higher than pure TiO2 and two-component Ag/TiO2, respectively. The enhanced photocatalytic activity could be mainly attributed to the reasonably designed heterojunctions and the electrical conductivity of Ag.
