| Research Abstract |
Multiphase reaction media including dense phase carbon dioxide and/or water have been applied for hydrogenation reactions, photocatalytic reactions, and so on. The practical usefulness of those reactions was examined and the physical and chemical functions of carbon dioxide and water were investigated. The reactions studied include selective hydrogenation of nitriles to primary amines, hydrogenation of phenol, photocatalytic water splitting, and others. In situ high pressure Fourier transform infrared spectroscopy was used to examine the interactions between carbon dioxide and organic substrates and those between supported catalytic metal particles and reacting species (carbon monoxide formed from carbon dioxide and hydrogen, organic substrates, water). There were observed acceleration of reaction rate, modification of product selectivity, and/or suppression of catalyst deactivation for those reactions in the multiphase media. The chemical functions of carbon dioxide and water d pended on the chemical reactions examined.
