Abstract

A new candidate for photocatalytic degradating organic dyes, CdS carried by carbon nanotubes (CdS/CNTs), is reported. The degradation ratio curves of methyl orange in water phase show that the capability for degradating organic molecules of CdS/CNTs is obviously higher than that of separated CdS. The degradation capability enhances as the increase of the amount of net CdS catalyst, the ratio of carbon nanotubes to CdS, and the area of the template, and is influenced by the pH value and the temperature of aqueous solution. These results suggest that the photocatalyst of CdS/CNTs is very suitable for potential applications in organic waste removal from water.
