New Type of Heterogeneous Catalyst with Isolated FE-RH Diatomic Sites

摘要

A totally new type of heterogeneous catalyst was created containing iron rhodium diad sites. These sites were totally different from traditional iron-rhodium alloy catalysts. They exhibited a constant selectivity and specific activity with the test reaction. These sites were prepared by the low temperature decomposition of an organometallic compound, (CO)3Fe(mu-C7H7)RhCOD, in a hydrogen atmosphere. The method of characterization employed involved the catalysts' selectivity towards the isomerization and hydrogenation of 1-butene. Catalysis was accomplished using a plug-flow differential microreactor at 30 C. These diad sites also appeared to be different from rhodium-only catalysts at monoatomic dispersions.
