X-ray study of titania- and alumina-supported rhodium catalysts for the hydrogenation of hydrocarbons

An X-ray study of titaniaand alumina-supported rhodium catalysts for the hydrogenation of hydrocarbons is performed. Rhodium is shown to be present in the form of highly dispersed oxide, independent of the type of support. The atomic structure of alumina changes, while no change in the real structure of titanium oxide is observed.
