Absorption spectral changes of 4CP aqueous solution (20 mg/L) degraded by 1D CdS@ZnS core-shell nanocomposites with irradiation timet: 0, 1, 2, 3, 4, 5, 6, 8, 10, and 12 h (a). Visible-light Photodegradation of 4CP 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)
