Abstract

HNbWO₆/(Pt,Cd_0.8Zn_0.2S) nanocomposites have been fabricated by successive intercalation reactions of HNbWO₆ with [Pt(NH₃)₄]Cl₂ aqueous solution, with n-C₃H₇NH₂/n-heptane mixed solution, and the Cd(MeCO₂)₂-Zn(MeCO₂)₂ mixture in aqueous solution, followed by the reaction between Cd²⁺-Zn²⁺ and H₂S in the interlayer of HNbWO₆. The gallery height of HNbWO₆/CdS*, HNbWO₆/Cd_0.8Zn_0.2S*, HNbWO₆/CdS, HNbWO₆/Cd_0.8Zn_0.2S, HNbWO₆/(Pt, CdS) and HNbWO₆/(Pt,Cd_0.8Zn_0.2S) is less than 0.5 nm in each case. HNbWO₆/(Pt,Cd_0.8Zn_0.2S) series nanocomposites show a broad reflectance over ca. 380-580 nm and are capable of efficient hydrogen evolution under the irradiation of visible light in the presence of Na₂S as a sacrificial donor. The photocatalytic activities of HNbWO₆/CdS and HNbWO₆/Cd_0.8Zn_0.2S nanocomposites are superior to those of unsupported CdS and Cd_0.8Zn_0.2S and are enhanced by the the co-incorporation of Pt.
