Novel preparation of metal-supported catalysts by colloidal microparticles in a water-in-oil microemulsion; catalytic hydrogenation of carbon dioxide

Abstract

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