Absorption spectral changes of MB aqueous solution (15 mg/L) degraded by 1D CdS@ZnS core-shell nanocomposites with irradiation timet: 0, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, and 6 h (a). Visible-light Photodegradation of MB under different conditions. Curves: (1) with CdS@ZnS core-shell nanocomposites, (2) with CdS nanowires, (3) with commercial Anatase TiO2, (4) without any photocatalyst, and (5) with CdS@ZnS core-shell nanocomposites in dark (b)
