N2 - In this study, we confirm a tetrahedral structure for a Co2+ complex in supercritical water instead of the octahedral structure in normal water. The absorption spectra of Ru2+ complexes were observed for only stable species such as [Ru(phen)3]2+ in supercritical water. The photochemistry of uranyl(VI)-tributylphosphate(TBP) complex in supercritical carbon dioxide (scCO2) was studied in the pressure range of 8-40 MPa and from 289 to 336K. In order to examine the hydrogen-bond structures and molecular motions of supercritical water and non-aqueous solvents, their 1H spin-lattice relaxation times were measured under sub- and supercritical conditions by using high-pressure NMR. NiMo/Al2O3 was chosen as a catalyst because of its catalytic activity for hydrocracking aromatic structures.
