Preparative methods for reduction of simple and complex metal oxides with supercritical isopropanol (SCI) and laboratory procedures for efficient handling SCI are developed. The optimum reaction conditions (temperature, pressure) and SCI-to-oxide ratios are determined. Dispersed oxides covered by thin films of highly dispersed metals are obtained. Such systems are prospective catalytic materials. Simple method for manufacturing metal nanoparticles by in situ SCI reduction of nanosized metal oxides stabilized in polyethylene and synthetic SiO2 (opal) matrixes are developed.
