Abstract:

Organic-anion-pillared layered double hydrotalcites such as Zn2AlTA(TA=terephthalate) are easily synthesized by using coprecipitation reaction of Zn2+ and Al3+ ions with terephthalic acid in NaOH solution. Exchange of this material under mild acidic conditions with the heteropolyanions proceeds smoothly to yield Zn2AlSiW11Co and Zn2Al-BW11Cu. Characterization has been carried out by elemental chemical analysis, powder X-ray diffraction and IR spectra. The results indicated that these materials possess exceptionally well-ordered gallery height of 0.98nm. It was found that this kind of pillared layered catalyst has high activity and selectivity for the oxidation of benzaldehyde to benzoic acid using H2O2 as oxidant in liquid-solid phase system.
