Intercalation of H4[a-SiW12O40].nHO polyoxometalate on layered double hydroxide by comparison weight rasio of layered double hydroxide:H2[aSiW12O40].nH O polyoxometalate 1:1 has been done. The result of intercalated layered double hydroxide was characterized using FT-IR spectrophotometer and XRD analysis. Characterization using FT-IR were not showed the optimal intercalation process. The succes…
