The Chemistry of Rhodium in Polysulfone : Reactions with Various Small Gas Molecules

摘要

RhCl [P(C6H5)3]3 complexes have been incorporated in polysulfone (PS) as a dispersion medium using cosolvent (THF). The interactions between Rh(グ) complexes and polysulfone polymer molecules are examined by infrared spectroscopy and thermal analysis. The chemical reactivity of Rh in PS films has been investigated by reacting Rh sites with CO, H2, D2, O2, NO, C2H2 and C2H4 in the temperature range 25-200 ∩. Various Rh-carbonyl, -hydride and -nitrosyl species formed in PS films are characterized by their infrared spectra. Rh complexes in PS film show interesting catalytic reactivities in the reactions such as hydrogenation of C2H2 and C2H4, oxidation of CO, and reduction of NO by CO or H2 gas under relatively mild conditions.
