摘要
A series of diphenyl-sulfide(Ph;S)-immobilized Pd/C catalysts(Pd-Ph;S;/C) were prepared using the wetness-impregnation and immobilization method.Pd-Ph;S;w/C catalysts employed for the hydrogenation of o-chloronitrobenzene showed very high selectivity.The structure of Pd-Ph;S;/C with different molar ratio of ligand(x-values) was characterized by XPS and TG-DSC-MS.The results suggest a "saturated" surface ratio of Ph;S/Pd(about 0.3) was formed on the Pd-Ph;S;/C catalysts surface.The Ph;S immobilized on the Pd particle is quite stable,and the desorption of Ph;S or dissociative loss of phenyl group was only found at temperatures above 500 K.The possible catalytic mechanism of the Pd-Ph;S;/C catalyst was also discussed.
