NOVEL PREPARATION OF METAL-SUPPORTED CATALYSTS BY COLLOIDAL MICROPARTICLES IN A WATER-IN-OIL MICROEMULSION - CATALYTIC-HYDROGENATION OF CARBON-DIOXIDE

A novel catalyst preparation method of employing microemulsions, and t he carbon dioxide hydrogenation activities of silica- or zirconia-supp orted catalysts loaded with colloidal rhodium microparticles in water- in-oil microemulsions are reported; the catalysts thus prepared exhibi t much higher activity than those prepared by classical methods.
