TiO2-CdS Nanocomposites: Effect of CdS Oxidation on the Photocatalytic Activity

Figure 7

Effect of the CdS proportion on the photodegradation of benzoic acid under visible light irradiation. Curves correspond to the best nonlinear least square fitting of pseudomono- or pseudobiexponential functions to experimental data. The characteristic times ( and ) that best describe the photodegradation kinetics are shown in the inserted table.
