Nanocomposite of CdIn₂S₄ was synthesized by direct feeding microwave synthesis method, using indium nitrate, cadmium nitrate and thioacetamide as raw material, cetyltrimethyl ammonium bromide(CTAB) as surfactant. The crystal structure, morphology and the optical property of as-prepared sample were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM) and Fluorescence spectra. The results showed that the as-prepared nanocomposite is hexagonal CdIn₂S₄. The SEM showed that the shape of these nanoparticles is irregular and looks like flake/sphere with some aggregation. The size of most of the aggregate is 100 to 300 nm. The photocatalytic activity of the as-prepared samples was studied by using degradation of methylene bule under visible light. The results show that the photocatalytic activity of CaIn₂S₄ photocatalyst was very well. When the catalyst was 1.0 g/L, C(H₂O₂) was 3 mL/L, after 120 min of the irradiation, the degradation rate of CdIn₂S₄ for methylene blue of 20 mg/L reached 86.06%.
