氰乙基化纤维素—Pd络合物加氢催化剂的X—射线光电子能谱研究

STUDIES ON X--RAY PHOTOELECTRON SPECTROSCOPY OF CYANOETHYL--Pd COMPLEX CATALYST

本文对氰乙基化纤维素—Pd 络合物加氢催化剂进行了 X—射线光电子能谱研究。证明其为络合物,并确定了催化剂中钯在催化前后的价态变化。

Cyanoethyl—Pd complex catalyst has been identified by X— ray photoelectron spectroscopy.This investigation showed that the complex was formed by transferring the lone—pair electron nitrogen atom of cyanoethyl to the palladium atom of pdCl_2 The oxidation state of palladium in the catalyst is 2^+ (pd^(2+)). It turned to zero (pd^0) in the used catalyst.
