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.

包括密集的二氧化碳和/或水在内的多相反应培养基已用于氢化反应，光催化反应等。研究了这些反应的实际实用性，并研究了二氧化碳和水的物理和化学功能。所研究的反应包括硝化液的选择性氢化，苯酚的氢化，光催化水的分裂等。原位高压傅立叶型红外光谱法用于检查二氧化碳与有机底物与受支持的催化金属颗粒与反应物种之间的相互作用（由二氧化碳和氢，有机底物，水）之间的相互作用（一氧化碳形成）。在多相介质中，观察到反应速率的加速度，产品选择性的改变和/或抑制催化剂失活的抑制。二氧化碳和水的化学功能持续了所检查的化学反应。
