Abstract

Preparation of nanomaterial based on polyoxometalate H3[a-PWi204o].nH20 with. Si02, Ti02, ZrOCl2, and TaCls was carried out to form H3[a-PWi204o].nH20-Si02, H3[a-PWi2O40].nH2O-TiO2, H3[a-PW,2O40].nH2O-ZrOCl2 and H3[a-PW]204o].nH20-TaCls. Nanomaterial from preparation was characterized through functional group analysis using FT-IR spectrophotometer, crystalinity analysis using XRD and surface photo analysis using SEM. The results show that nanomaterials H3[a-PWi204o].nH20-Si02 and H3[a-PW|204o].nH20-TaCls were the best nanomaterial from preparation. FT-IR spectrum shows specific wavenumber for nanomaterial H3[a-PW]204o].nH20-Si02 in the range 462-1620 cm"1 and H3[a-PWi204o].nH20-TaCls in the range 516-1620 cm"1. XRD pattem for nanomaterial H3[a-PW|204o].nH20-Si02 and H3[a-PWi2O40].nH2O-TaCl5 show there is a different between polyoxometalate H3[a-PW1204o].nH20, Si02 and TaCls. SEM photo analysis shows nanomaterial H3[a-PWi204o].nH20 and H3[a-PW|204o].nH20-TaCl5 has nanosize with homogeneous distribution size. FT-IR spectrum and XRD pattem of H3[a-PW|2O40].nH2O-TiO2 and H3[a-PWi204o].nH20-ZrOCl2 did not show the supporting of Ti02 and ZrOCl2 to polyoxometalate to form nanomaterial. Nevertheless SEM photoanalysis show homogeneous distribution and size of H3[a-PW12O40].nH2O-TiO2 and H3[a-PW|204o].nH20-ZrOCl2 and classified as nanomaterials.
