Abstract

The catalyst is prepared by reaction of a rhodium-π-allyl complex, Rh(η3-C3H5)3, with surface OH groups of TiO2 and subsequent H2 treatments at different temperatures.

ChemInform Abstract

The catalyst is prepared by reaction of a rhodium-π-allyl complex, Rh(η3-C3H5)3, with surface OH groups of TiO2 and subsequent H2 treatments at different temperatures. Catalysts prepared by this method show higher catalytic activities for ethene hydrogenation and hydrogenolysis than conventional, impregnated Rh/TiO2 catalysts. In contrast to the impregnated catalysts, the new catalyst show no SMSI (strong metal-support interaction) phenomena.
