摘要：

Pd(OAc)2 complex has been incorporated in cellulose acetate (CA) as a dispersion medium using cosolvent (THF). The interactions Pd(II) complexes and cellulose acetate are examined by infrared spectroscopy and thermal analysis (DSC). The chemical reactivities of Pd-CA films have been investigated by reacting Pd sites with CO, H-2, O2, and C2H4 in the temperature range 25-150-degrees-C and at the pressure of less than 1 atm. Two different Pd-carbonyls and a Pd(O)-hydride species formed in CA are characterized by their infrared spectra. Treatment of 10 wt % Pd-CA films with hydrogen (600 torr) at 70-degrees-C produces small Pd metal particles of ca. 30-60 angstrom in diameter in CA, which show catalytic activities under mild conditions in the reactions such as hydrogenation of C2H2 and oxidation of CO.
