Authors: Arakawa Hironori , Fukushima Takakazu , Ichikawa Masaru , Takeuchi Kazuhiko , Matsuzaki Takehiko , Sugi Yoshihiro 
Published: July 2006

Abstract
The behavior of adsorbed CO and reaction intermediates on Rh/SiO2has been observed at high pressure CO hydrogenation condition by in situ FT-IR spectroscopy. A good relationship exists between turnover frequency of CO conversion and the ratio of bridged-CO/linear-CO adsorbed on Rh/SiO2 at the reaction condition in terms of Rh dispersion of catalysts. Turnover frequency increases with the increase of this ratio as a general trend. Two kinds of acetate species as reaction products on SiO2 have been observed.

PHOTOGENERATION OF HYDROGEN FROM WATER WITH MIXED SEMICONDUCTOR CATALYST
Authors: Kobayashi Junya , Kitagushi Kenichi , Tsuiki Hideyasu , Ueno Akifumi , Kotera Yoshihide 
Published: July 2006

Abstract
Alumina-supported mixed semiconductor catalyst, ZnS·CdS/Al2O3, showed a significant rate of hydrogen generation from water under UV irradiation without an assistance of any noble metals. Singly supported catalyst, ZnS/Al2O3 or CdS/Al2O3, showed, however, less activity for photogeneration of hydrogen. The activity was not improved by physical mixture of ZnS/Al2O3 and CdS/Al2O3 although the amount of ZnS and CdS were the same as those in the ZnS·CdS/Al2O3 catalyst. This indicates that the intimate contacts between ZnS and CdS particles are necessary to photogeneration of hydrogen.
