Abstract: Tungstogallic heteropolyanion trisubstituted with transition metal cobalt was intercalated into ZnAl-NO3 type anion clay by means of hydrothermal ion-exchange for the first time.IR spectra show that Keggin structure of the intercalated hyteropolyanion was kept perfect. Powder X-ray diffraction confirms that the intercalation reaction takes place and the gallery height of intercalated product is 0.99±0.01 nm.Catalytical tests exhibit that the intercalated derivative shows a higher catalytic activity for the formation of DOP.

Key words: Transition metal, Trisubstituted heteropolyanion, Intercalation, Anion clay
