植酸修饰聚乙烯醇纤维膜负载钯催化剂的制备及其性能研究
Phytic acid modified poly (vinyl alcohol) fiber mats supported palladium catalyst and its catalytic performance
摘要
Abstract
Phytic acid modified poly (vinyl alcohol) fiber mat is prepared by electro spinning and used as the support‐ing materials of palladium catalyst .The fiber morphologies are recorded by scanning electron microscopy (SEM ) and the dispersion of palladium particles is analyzed by SEM‐Energy Dispersive Spectrometer (SEM‐EDS) .FT‐IR spectra are used to characterize the chemical structure of the fiber mat .The catalytic performance of this novel cata‐lyst is evaluated by Mizoroki‐Heck reactions .The results show that this catalyst is very efficient for the Mizoroki‐Heck reaction of aromatic iodides with yields being over 85% .Moreover ,the catalyst could be used four times with only little loss of catalytic activity .关键词
