Abstract

Photocatalytic activity of the CdS thin film depended very much on the film density, adhesion between the CdS and substrate, and whether effective electron path existed or not. We have proposed the formation of a bridging layer of Cd metal to improve the film density, adhesivity and the electron conduction path. Here, we report the results of the study undertaken to develop CdS/Cd (dendrite)/Ti film with enhanced photocatalytic property to decompose hydrogen sulphide. CdS/Cd (dendrite)/Ti photocatalyst showed the highest photocatalytic activity and photocurrent, which was 1.4 times higher than the traditional CdS/Ti photocatalyst.
