Abstract
The prospective ways of using water in sub- and supercritical states for th e preparation of nanocrystal oxide catalysts Ce0.5Zr0.5O2, Ce0.1YxZr0.9-O-x (2), Zr1-xYxO2, Zr1-xInxO2, La2CuO4, supported catalysts Pd/Rh/ZrO2 and Pd/ Rh/TiO2, and supports CeO2, ZrO2, TiO2 are discussed. The proposed techniqu e is characterized by high productivity. It is also ecologically friendly a nd enables one to obtain multicomponent oxide catalysts with chemical and p hase composition and properties that can be changed within large ranges. Th e physicochemical properties of sub- and supercritical water are discussed. A brief review of the present studies on the use of critical media in vari ous physicochemical processes is given.
