Abstract

A series of Zn_xCd_1-xS solid solutions supported on Al₂O₃ were prepared, and investigated in the plasmainduced H₂S decomposition. Structural and optical properties of the as-prepared catalysts were characterized by XRD, N₂ physisorption, UV-vis, TEM and XPS techniques. All Zn_xCd_1-xS/Al₂O₃ catalysts showed relatively high activities for H₂S decomposition. The catalytic activity is found to increase gradually when the Zn concentration on catalysts increases from 0.2 to 0.6. Subsequent increase in the Zn fraction up to 0.8 leads to lower H₂S conversion. Variation in activity is discussed in terms of modification in the conduction band and light absorption ability of Zn_xCd_1-xS/Al₂O₃ derived from the changes in the Zn/Cd molar ratio.
