AgIn{sub 5}S{sub 8} powders were successfully synthesized by a microwave hydrothermal method for the first time. This method is a mild and highly efficient route involves no templates, catalysts, or surfactants. Therefore, it is very promising for the low-cost and large-scale industrial production. The samples were characterized by X-ray diffraction, UV-vis spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscopy. The photocatalytic activity of AgIn{sub 5}S{sub 8} nanoparticles was investigated through the degradation of methyl orange under visible light irradiation. Compared with TiO{sub 2-x}N{sub x}, AgIn{sub 5}S{sub 8} has exhibited a superior activity under the same condition. A liquid chromatogram-mass spectrometer was used to separate and identify the dye and degradation products generated during the reaction. According to the experiment results, a possible mechanism for the degradation of organic pollutant over AgIn{sub 5}S{sub 8} was proposed. - Graphical abstract: Compared with TiO{sub 2-x}N{sub x}, AgIn{sub 5}S{sub 8} has exhibited a superior activity under the same condition.
