A STUDY ON THE STRUCTURE OF POLYMETHYL PHENYL SILAZA-SILOXANE-Pd COMPLEX BY X-RAY PHOTOELECTRON SPECROSCOPY (XPS)
The structure of polymethylphenylsilaza-siloxane-Pd complex catalyst has been investigated by X-ray photoelectron spectroscopy (XPS). The experimental results indicated that the complex is formed by coordination of two lone pairs of electrons on two nitrogen atoms in polymethylphenylsilaza-siloxane to one palladium atom in palladium dichloride. The inactivation of the complex in the hydrogenation of olefines is due to the destroy of the complex and the reduction of Pd(Ⅱ) to Pd(0).
