Synthesis of CdS Sensitized TiO₂ Photocatalysts: Methylene Blue Adsorption and Enhanced Photocatalytic Activities

Figure 9

(a) Profiles of photocatalytic degradation of MB with time and NLF of experimental data to the apparent pseudo-first-order kinetics model over the different photocatalysts (white section). (b) Comparison of apparent rate constants (blue plot) of photodegradation of MB with the band gaps (red plot) of the corresponding photocatalysts as a function of Cd : Ti molar ratio. Experimental conditions: 0.1 g catalysts,  K 35 W Xenon HID light irradiation.
