Fabrication and Photocatalytic Properties of ZnSe Nanorod Films

Figure 6

Absorption spectrum of the MO dye solution in the presence of the ZnSe nanorod film (12 h) (a) and the ZnSe film (b) under ultraviolet light irradiation for various time durations. (c) Photodegradation curves of the MO dye solution under ultraviolet light in the presence of the ZnSe nanorod film (12 h), the ZnSe film, and no catalyst and under no ultraviolet light but in the presence of the ZnSe nanorod film (12 h). (d) Degradation change as a function of irradiation time (1.5 h and 3.0 h) over 5 cycles. The initial concentration was taken to be the same as in (a).
