Four-component calcium metasilicate (CaSiO3)-loaded Ag-AgX/TiO2 (X = Cl, Br, I) photocatalysts were fabricated by chemical precipitation, photoreduction and physical adsorption processes. Calcium metasilicate material was obtained in our previous work. This is first reported Ag-AgX/TiO2/CaSiO3 (X = Cl, Br, I) composites which were employed according our plans. The surface structure and morphology of as-prepared products were conducted by scanning electron microscope (SEM); the valence state of Ag element in Ag-AgX-TiO2 (X = Cl, Br, I) were confirmed by the analysis of X-ray photoelectron spectroscopy (XPS). The optical properties of Ag-AgX-TiO2/CaSiO3 (X = Cl, Br, I) were investigated by UV-vis spectrophotometer. The visible light photocatalytic for degradation of polycyclic aromatic hydro-carbonsmethyl (MO, sodium fluorescein (NaFI) and ethyl rhodamine B (ERB)), the experimental results showed that the Ag-AgX-TiO2/CaSiO3 (X = Cl, Br, I) possessed high activity for the three organics under visible light irritation (lambda > 400 nm). The novel composite photocatalysts have profound potential applications in dealing with environmental pollutants. (C) 2015 The Society of Powder Technology Japan.
