| 英文摘要 | a series of heteropolyphosphatotungstate catalysts with different w/p ratio were prepared by different means. p-31 mas nmr spectra show every heteropolyphosphatotungstate contains several species with different w/p ratio. combined with propylene epoxidation results, it is shown that the band at chemical shift ca. delta = 5 ppm maybe corresponds to a catalyst precursor which can be the most efficiently converted to the structure {po4 [wo(o-2)(2)](4)}(3-). characterization results of icp show, the catalysts with low w/p ratio show a good reactivity for propylene epoxidation.
