Abstract

Cd0.8Zn0.2S pillars were constructed in the interlayer of H1-xCa2-xLaxNb3O10 (x = 0-0.75) by the stepwise intercalation reactions. The height of Cd0.8Zn0.2S pillar was less than 1 nm and the band gap energy of Cd0.8Zn0.2S pillar was slightly larger than that of normal crystalline one. Cd0.8Zn0.2S pillared compounds showed photocatalytic activity for hydrogen evolution in the presence of sacrificial hole acceptor such as Na2SO3 by the band gap irradiation. The photocatalytic activity of Cd0.8Zn0.2S incorporated was superior to that of unsupported one and was improved by doping La3+ ion in the host layer. The heterogeneous electron transfer from guest Cd0.8Zn0.2S to host Ca2-xLaxNb3O10 layer seemed to play an important role to enhance the photocatalytic activity.
