Pillarization of double layer hydroxides using H3[-PW12O40]nH2O: effect of pillarization time
Year: 2017
Type: article
Abstract: The pillarization of Mg/Al double layer hydroxides using polyoxometalate H 3 [α-PW 12 O 40 ]· n H 2 O by comparing the pillarization time i.e. 3 hours, 6 hours, 9 hours, 12 hours, 24 hours, 36 hours and 48 hours has been done. The product of a pillarization was characterized using an FT-IR spectrophotometer and XRD analysis. The result characterization of FT-IR spectrophotometer does not show the optimum of pillarization each time condition. Characterization using XRD shows the optimum pillarization process at 36 hours by showing the existence of double layer hydroxides material at diffraction angle 11.69 o deg, 18.30 o deg and 34.71 o deg. Diffraction in the 60 o -63 o deg indicates the existence of a pillarization double layer hydroxides. Keywords : Layered double hydroxides, pillarization, polyoxometalate H 3 [α-PW 12 O 40 ]· n H 2 O.
